FtlrdieHerstellung of Zweikomponentendiazotypiematerial, which contains a Diazoverbindung and a one to the Knpplung with this qualified connection, and by which borrowing breaks with red and braunmten colours can be manufactured after the Tmekenveffahren, to have as Diazoverbindungen diazotierte p-Phenylendiamine with tertiary Sticl toffatom and as clutch components of amides of the 3, 5-Dihydroxy-bermoesäure (Resorcylsäure) works satisfactorily. To the Verbauerung of the water firmness of the breaks manufactured with this material one suggested to see 3, 5-Dihydmxy-benzoesäureatylamide, to e.g. 3, 5-Dihydmxy-benzoes ureanilid. The use of these connections for the production of the photo-sensitive layers from aqueous Lööungen is however difficult by their bad water solubility. It winds now found that this disadvantage is to be repaired and - on use in the Diazotypie common Diazoverbindungen - much it strengthens Lich ausen with red colours is producible, if in liehtempfindlichenSclüeht as clutchable connection, if necessary as salt available, substituted 2 [3 ', 5 ' - Dihydroxyphenyl] - benzimidazol the general forms! HO [OH I I I I blank or a mixture of several of these connections is present, whereby in the formula g 1 hydrogen, a low Alkylgmppe or a substimierte low Alkylgtuppe, RZ hydrogen, a low alkyl group, a low alkoxy group or a halogen atom with a Atomgewieht of highest 80, and Rn hydrogen or bromine mean. Blank is prefers an alkyl group with highest 3 Kohlensmffatomen. If blank is substituted, one or more amino groups are appropriate for hydroxyl group or substituted amino groups forwards as substituents prefer. Suitable ones substituted Aminograppen are particularly low alkylated amino groups, in addition, dialkTIierte Aminagruppm, in those the two allyl groups over a KoMemtoff, Sauerstoffbzw. Is, as for example the Pyrrolidino, Piperidinooder Morpholinogruppe preferably interconnects nitrogen atom to one to 8oder 6-gliodrigen ring. Blank represents prefers methyl, Methoxyoder Äthoxygruppe or as halogen atom a chlorine atom. The formulas of some according to invention used of the 2 [3 ', 5 ' - Dihydroxyphenyl] - benzimidazole are the Tabolle to be taken. The connections are again and draw by grolle stability both in substance and in solution and in the photo-sensitive layer to. In form of its salts this substituted Benzimidazele is water soluble. The salt screen end group of X0 is in the heterocyelischen ring. The basicity of this ring can be strengthened by the substituents specified above ftir the remainder of blanks, because a further salzbfldende group is then present. For the Salzbildung are suitable see natural both anorganiseh¢ acids, and hydrochloric acid and sulfuric acid, and organic acids, like vinegar, äure, Zirronemäure or Weimäum or also mixtures dieser8äuren. It is not necessary always to isolate the salts. .qie forms for example also with addition of the free bases to the Semibilisierungflösungen containing the Diazoverbindungen, which contain acids as Stabflisatorcn llberschtlssigc. To the production according to invention of the used of the 9 - [3 ', 8 ' - Dihydroxyphenyl] - bermimidazole one can do of the underlying acylierten, usually aoetylierten 3, 5-Dihydrexy-benzoesäureehloriden to go out. These can substitute on the two following because of into the gewtlmchten Benzimidazole to be over-granted: a) One semt the acylierten 8 halogenmbstituierten if necessary, 5-Dihydroxy-benzoe äurechlorid “with o-Phenylendiaminen over, in which the substituents blank are already present tmd blank, soaps the aeylierten Hydmxygruppen, for example with diluted caustic soda solution, and verkoeht the received 8, 5-Dihydmxybenzoesäure-o-aminophenylamide with center more tarker to more strongly, for example about 30% iger SalzeS acid, whereby under Wasserabspaltung of the Benzimidazolring one forms. If necessary kölmen the Entacylierung and the Ringschlußreaktion with strong Salzsäme in a stage to be durchgeftthrt. b) One converts the acylierten 3, 5-Dihydroxy-benzoesäurechloride with o-Nirxanilinen, halogemubstituierten if necessary, in which the substituents blank and blank are already present, and reduces DL “received O-acylierten 3, S-Dihydroxy-benzeesäure-o-nitmphenylamide to the concerned -, set free into this through soaping with verdilnntcr caustic solution, usually caustic soda solution, dic both hydroxyl groups o-aminophenylamiden and close then the Imidazolring appropriately by cooking with glacial acetic acid in presence of small quantities more concentrated. %hwefelsäum. A specification of these two Herstellnngsmethoden is given to 1 in example for the method A and in example 3 of the method b. Suitable p-Phenylendiamine, di “in diazotierter form as well as the 9 the according to invention - [3 ', 5 ' - Dihydmxyphenyl] - to be used, are primarily such benzimidazolen, at the nitrogen atom two low Alkylbzw p-constant to the Diazogruppe. Hydroxyall lgmppen contained, whereby also here the Alkylgmppen over a Kohlemtoff, Sauerstoffbzw. Nitrogen atom zn one 5oder 6-gliedrigen ring to preferably be connected know. Diazotierte p-Phenylendiamine with tertiary nitrogen atom, which additionally still contains two z each other in the core or preferably p-constant low alkoxy groups, particularly Methoxyoder Äthoxygruppen, is particularly suitable. Genarmtseien for example the salts of X-Diazo-4-diäthylaminobenzol, I-Diazo-4-dipropylamino-bermol, 1-Diazo-9-äthoxy-4-diäthylamino-benzol, 1-Diazo, 4 [hydroxyäthyl äthylamino] - benzene, 1-Diazo-2, 5-dimethoxy-4-inorpholino-benzol, 1-Diazo-9, 5-diäthoxy-4-morpholino-benzol. According to invention used the 2 [3 ', 5 ' - Dihydroxyphenyl] - benzimidazole are suitable together with genarmtcn the diazotiertenp Phenylendiaminen both for the Semibilisierung of normal Lichtpampapiere and for the production of photo-sensitive layers on Tramparentpapieren and foils. In the first case one brings the subsrätuierte Benzimidazol from purely aqueous solutions on the carrier, in the latter case is the use of L'Osungsmitteln, in particular to low aliphatic alcohols, preferably Impropylalkohol, necessary. In the solutions can be used into the Diazotypie usual additives, which increase the stability of the layers and cause a antivergilbenden effect. The greater technical importance is attached to the Diazotypicmatcrial manufactured with transparent slow-acting one. Panen manufactured of it shows in practice desired saving. One uses such copies for colored projections, for example for Lehrzweoke, particularly in the school teaching. They are further suitable for the production of well visible zwischenoriginalen intended for the Weiterpanen. In the latter case it is necessary to along-use a second Azokomponeme which results in a yellow coloring material with good cover strength against fnr the exposure the used kind of light. The invention becomes by the following examples and the table erll'tnterr. In the table r of the formula of the substimierten Benzimidazols concerned is the Hemtellungsmethode A) and/or, b) (see above) as well as the point of decomposition indicated in °C. The Formelunmmein indicated in the Beispinlen corresponds to those the table. In the examples 1 valley is considered as unit volume, if as Gewichrseinheit 1 g is taken. Example I: On, which is provided Polyvinylacerat, a solution of 4 thread - parts of Zitmnensäure 2 thread - becomes more l.ächrpauspapter parts of O, 5 VOL. - Parts of 4 thread - parts of 3 thread - parts of 1 thread - Teü 2 thread - parts of 100 VOL. - T flen me a pre-coating of colloidal silicic acid and boric acid konz.
