PATENT OFFICE PATENT SPECIFICATION No. 284880 class: 15 b 17/02 lnt. El.: B 41 m 5110 expenditure day 12 October 1970 THE NATIONAL CASH REGISTER COMPANY IN DAYTON (U.S.A.) DruckempfindIiches recording sheet announced on 31 October 1968 (A 10610/68); stressed priority “Pateutansprflche 1 - 5 and 9 from 2 November 1967 (680251), PatentamprUche 6, 7, 8 and from 2 July 1968 (770878) (registrations in the United States of America). Beginning of the patent continuous “15. Feber 1970. The invention concerns a pressure-sensitive “autogenous” recording sheet, which contains all necessary components, in order to produce when influencing pressure the Druekmuster appropriate colored indication. Bekalmte autogenous ckuckempfindliche Aufzeielmungsblätter consist of a carrier sheet, which exhibits a coating of bio caps, which a colorless Farhreagens solved in an oily solvent to contain and in their direct proximity see fine TeiIehen of the mineral Attapulgit to find, which causes as a sour adsorbtereudes reagent the transformation colorless color reagent into its colored condition. This Aufzeicbnungsblätter is very susceptibly more gegentlber during the handling the same unintentionally caused pressure. Since Attapulgit is a mineral insoluble in the oily solvent, a further disadvantage arises as a result of that the reagent is on the surface of the Attapulgitteilchen. In order to switch off the latter disadvantage, one suggested, replacing the Attapulgit by a sourly reacting öUösliches phenol. The phenol is loosened in dern solvents oily from the broken open caps released and forms a colored oily liquid, not by RST an adsorbent surface reaction, but by a acid base Reaküon, with the colorless reagent extremely easy flowing is permitted and thus a complete reaction with the Gcsamtmasse of the color reaction means, what there the case is not, where in oil a Ilichtlösliches material is used. It turned out however that such sheets do not respond correctly to pressure. The invention decreases the disadvantages mentioned, by planning a autogenous Aufzeiehnurtgsblatt with a double coating of the carrier sheet. The first, lower layer consists of a multiplicity Miktokapseln, which contains one or more normally colorless chromogene connections solved in solution in a solvent, from very short cellulose fibers and from a sourly reacting clay/tone, and the second, upper layer, which see in direct proximity to the first layer rules, contains at least a phenolic resin, kaolin and alternatively a salt of an element of the group of 95 9.B, an element of the group of 2A or a transition element, depending on, soft color or hue of the indication is wished. Everyone of the two neighbouring layers can contain a bonding agent, and zw. up to 20% of the entire solid quantity. It was shown that by this structure the sheet can be together-rolled and/or rolled up, without thereby a unerwtlnschte color reaction arises due to the relative motion between two of its winding situations, if rolling up seh closely effected and it nevertheless maintains its AmprechempfindLichkeit for during the writing and marking ausgeflbten pressure, so that it is suitable for example for the production of sets of forms. Such recording material, which exhibits on the one hand no “Versehmiereffekt”, on the other hand however a sufficient sensitivity possesses, is of special importance, where a such sheet material is handled by Papierbearboitungsmaschinen and Dmckmaschinen, DO t, where its treatment stands except control or where it unbe - is correct is, how many sheets for the production of a Mehrfachformularsatzes use finding see. Accordingly the invention a durckempfndliehes consisting of a carrier sheet plans recording material, which carries a multiplicity of by dirt aufbreehbaren lvlikrokapseln, of which everyone a solution from at least a normally colorless basic chmmogenen connection contains, which drink reagent, which is added to the bio caps, with Berflbxung with one become colored. The according to invention on eiclmungsmaterial is characterized by it that the citizen sheet two layers finding with one another in unmitthlbarem contact exhibits itself, of which the first, lower i0 layer from a mixture from Mikzokapseln, very short cellulose fibers and much purifies particles of sourly reacting kaolin exists and of a mixture of very fine particles of a sourly reacting ö1iösllchen phenolic polymers and sourly reacting kaolin consists the second, upper layer. In the following tables the best suitable components, like them in the compositions of the first, are untern layer as well as the second, upper layer available are mentioned, as well as of them zulässi s and most favorable KonTent2ationen.

The solved chromogenen materials become in totally enclosed the Verwöndung according to invention. Generally at least 1 thread in that solvent should grant - % preferably of the chromogenen material existing in a surplus of L o and an appropriate quantity of a phenolic poI ymeren material to be soluble, thereby! 0 an effective reaction comes off. In the preferential Ausfllhrungsbeispiel the solvent should be however in the situation solving a surplus of the polymere material in order to use the existing chromogene material as completely as possible and to thus guarantee the maximum colour in a reaction place. In the following examples are mentioned fflr suitable oil-soluble basic photo chrome connections, but are not the invention not on the use of these connections limit Arylphthalide, like 8, 3 - to - (p-Dimethylaminophenyl) -6 - dimethylaminophthalid (Kristallviolett Lakton); 8, 8 - to (p-DL - methylaminophenyl) - phthalid (Malachitgrün Lakto); 9-Diäthylami o-spiro (12-H-benzo xanthen -12, l' phthalid); 3, 3-bis (1 - Äthyl-2-methylindol-3-yI) - phthalid; Leucauramine, how from N-Halopheny! -, in particular n (2,5-Dichlorophenyl) - leucauramin; Ecyl aura mine, like N-Benzoylauramin and N-Acetylauramin; Aura mine, like N-Phenylauramin; insatiated a-0 - Arylketone, like DianisyIidenaceton, Dibenzylidenaceton and Anisylidenaceton; basic Monoazofarbstoffe, like p-Dimethylaminoazobenzol-o-carbonic acid (methyl red), 4-Aminoazobenzol (oil yellow AAl]), and 4-Phenylazo -1-naphthylamin; Rhodamin B lactams, like n (p-Nitro-phenyl) - Rhodamin B lactam; Polyarylcarbincle, as to (p-Dimethylaminophenyl) - methanoI (Michler HydroD, KristalIviolettcarbinol and Malachitgrtlncarbinol; 8 ' - Methoxybenzoindolinospiropyrane, like 8 ' - Methoxybenzoindolinospiropyran, 4, 7, 8 ' - - Trimethoxy benzolndolinospiropyran, 6 ' - Chloro-8' methoxy benzoindolinospiropyran; Aminostyrylchinoline, like p-Dimethylaminostyrylchinolin; Fluorane, like 2-Chloro-6-diäthylamino-3-methyl - fluoran. Although a g can find oße number more oil-solubly, i.e. in organic Lösungsmifieln of soluble phenolic resins in this invention use, the sour phenolic reagent consists mainly of a permanently fusible, linear, oil-soluble condensate of an aldehyde, e.g. an aliphatic aldehyde, like formaldehyde, or an aromatic aldehyde, like Benzaldehyd, and one or more parasubstituierten Phenolen, whereby the condensate mentioned normally contains in the Dv.rchschnitt three to eight repetitive phenolic units. If the condensate is applied as aqueous dispersion on the paper, it should exhibit a softening point of at least 60oc, preferably of %oc. One receives the softening point for a given condensate as follows: Resin particles become on a gradue! l staff warmed up from 50 to 110oC aufgestäubt. After 1 min by means of an air flow those particles, which do not stick to the bar, are blown away. The temperature of that point at the staff, to which the resin particles begin to stick first, is the softening point mentioned. The Parasubstituenten knows c1 to c1 z, normal, ISO, tertiary or Cyclo alkyl, aryl, Aralkyl and alkene aryl as well as e.g. p-substitutes phenol with different p-Substiülenten to be, from those. Mixtures with the same aldehyde to be condensed can. If p-Alky! - to be used, the p-alkyl-Subsfituent normally contains substituted Phe - nole in such condensates 4 to 9 carbon atoms. AI suitable p-substituterte phenol, which can be condensed with formaldehyde and used in this invention, is mentioned in the following some examples " p-Methylpheno1; P-Äthylphenel; P-n-Propylphenol; P-n-Isobutylphenol; P-t-Butylphenol; pn amyl phenol; P-n-Hexylphenol; P-Cyclohexylphenol; P-n-Heptylphenol; P-n-Octylphenol; p-ISO-octylpheno! ; polarize, 1.3, 3-Tetramethyl-butylphenol; P-n-Nonylphenol p-Decylphenol; P-Undecylphenol; P-Phenylphenol; P-Benzylphenol; P-Tolylpheno!: Isomers the phenol mentioned and mixtures, which contain 7 in each case, wei or several the above phenol or their isomers. The preferential softening point mentioned of 73°G and over it is selected, in order to avoid a softening of the resin during drying the upper layer in usual Beschichtungsvorrichümgen. A such softening or causes difficulties behn for meals and with further processing steps, there the resin e.g. at warm Meta! loberfächen would cling. In addition the danger exists when that the resin particles flow together and in such a way form resin agglomerates, which are not as well effective regarding the Farberzeugnng as the individual particles. the one which can be planned, consisting of individual particles, in the paper-manufacturing industry kaolin is general under the designation China Clay " well-known and is unequalled as in the coating, in oil and water insoluble oil-adsorbing material. White kaolin is used, which represents an ideal a material due to its white color, its blättchenförmigen particles, which lend unequalled coating characteristics in an aqueous mash to it, its frequent occurrence, to its general use in Papierherstellungsund Papie working on industry and its low costs. Naturally there are many other materials of mineral condition, which in place of kaolin use will can and also einemVergieich with this regarding its favourable characteristics withstand. Other kinds out of the individual particles existing and essentially colorless, in water and ÖI unsolvable sourly reacting minerals, which exhibit the necessary adsorbent characteristics and of those some Bentonite are, are considered than equivalents of kaolin, although they are regarded from the theological point of view not as good as kaolin. In eister line from Kao! in and pheno! ischem resin existing upper layer in accordance with this invention can be sensitized with metal salts, for example with Zinkchlorid. The Hinzufolgen of these salts increases the Farbaktiviemngsn igung the mixtures from kaolin and phenolic resin and increases also the Widerstanddähigkeit opposite color chwund the colored form of the normally colorless chromogenen connections. As metal salts such are suitable, dis a Werttgkeit of 2 exhibit. After their meaning there is salts of the 2B-Metalle, i.e. from zinc, cadmium and mercury, the 2A-Metalle, i.e. from calcium, magnesium and strontium, and the transition metals, i.e. from manganese, cobalt and nods!. The effective metallic connections, which are helpful for the production of the layer composition in accordance with the invention as well as for the production of kaolin and phenolic resin containing Papterbeschichtungen, are the halides, nitrates, sulfates and acetates of metals from that zinc, cadmium, mercury, calcium, magnesium, strontium, Barinm, manganese, cobalt and nickel comprehensive group. in a11gemeinen through derL additive of salts of the metals of the groups of 2B, 2A and the transition metals results into the coating mass a larger Inte consisting of kaolin and organic resins ität the printing and a increased ruggedness of the printing in relation to light and warmth. Of that selection managing specified of materials a number of different Zusammensetaungen can be made on dry phloem, from which an aqueous mash is then prepared. With this mash a finished paper sheet or one can still hates paper web during their production to be coated. Further this mash can do also as a Dispersionsbeschichtuug on sequential 88 filma a tige course from synthetic organic polymers, from which recording sheets, - volumes or - touches be manufactured can, or also on arbitrary other carriers in the most favorable in each case and/or desired thickness to be laid on. The aqueous dispersion out of the individual Tei! - chen existing material can for example of 30 to 80 thread - % water and 70 to 20% firm reaction means consist. Still another adhesive is added to the coating mass, in order to achieve the necessary adhesion of the particles at the carrier. However no such Klehernittel is to be used, which is inclined to cover the particles. Also should be admitted no more adhesives, than for achievement the desired adhesion necessarily, since otherwise the color reaction activity was decreased unnecessarily. In connection with liquid Austauschund additives also silica-gel must be mentioned, since it is capable of the presently/immediately strong colouring of oil solutions from normally colorless chromogenen materials and represents a good oil receptor for oil coloring materials. Always then, if the particles of kaolin and sourer polymere material exhibit a leiohte delay of the color reaction due to their situation in the carrier sheet, the additive of silica-gel is in a quantity up to that drinks polymere material due to its Eigenschai%en specified above appropriately, but is not necessary its use for the invention in its simplest form. The expression “acid” used in the description includes completely generally also Lewis acids and is bescbxänkt in no way on a special definition. The autogenous recording material according to invention provided on a side with two layers can be on its back provided with a dmckempflndlichen transmission layer, over e.g. to produce a copy of the printing on an underlying sheet. Suitable fibrous substrate can be made easily of a liquid, generally aqueous mash or a wet mass of arbitrary paper-forming fibers, which form an even fibrous course, whereby the most common fibers are cellulose fibers from rags and wood, which are usually used for the production of paper. Other intermittent, arbitrarily oriented fibers as well as mica panels and panels from synthetic mica or other fiber screen end of solids (e.g. Fibers from Polyacrylnitrüen, polyesters and PP, which can be processed in a paper trade machine from a mash to an even document from fibrous material) to be able to be used likewise. Example 1 " a preferential example of a autogenous recording sheet, which results in a black pressure in the case of breaking the caps open according to the influencing Drackmuster, consisting of two layers, is described in the following: Composition of the first layer: Thread - % in the Bestandtelle dry layer a solution from Kristallviolett Lakton and 6 ' - Chloro-8' methoxy indolino benzopyry! ospiran containing micro caps cellulose fiber of very small length, in the Hande! as “Solka Floc” available and by the manufacturer, the company Brown CO, Berlin, New Hampshire, the USA as BW-200 designation very fine particles of calcinierten kaolin (e.g. of the Fkma Englehard of mineral and Chemica!
