Process for incorporating an inorganic substance into paper particles

PRINTING MEDIA SHEET

La présente invention a trait à une feuille support d'impression, utilisable dans un procédé de reproduction à pression, sensibilisée par un revêtement produisant une marque colorée lors du contact d'une solution huileuse avec un précurseur de colorant chromogène pratiquement incolore. Auparavant, ces revêtements étaient normalement constitués d'argile, telle que le kaolin, d'une résine phénolique soluble dans l'huile, telle qu'une résine phénol-formaldéhyde modifiée par un métal et d'un liant. Or, on a constaté, depuis, que l'addition audit revêtement de granules de particules agglomérées d'un pigment à base de résine urée-formaldéhyde reticulée, pratiquement insoluble dans l'eau, se traduisait par une plus forte intensité de l'image, une plus grande vitesse d'impression et un excellent contraste entre l'image et le fond. The present invention relates to a printing carrier sheet, suitable for use in a pressure reproduction process, sensitized by a coating producing a colored mark upon contact of an oily solution with a substantially colorless chromogenic dye precursor. Previously, these coatings normally consisted of clay, such as kaolin, an oil-soluble phenolic resin, such as a metal-modified phenol-formaldehyde resin, and a binder. However, it has since been observed that the addition to said coating of granules of agglomerated particles of a pigment based on crosslinked urea-formaldehyde resin, practically insoluble in water, resulted in a stronger intensity of the image. , faster printing speed and excellent contrast between image and background.

Abstract Process For The Production Of Record Material A colour developing material is produced by: a) gradually adding a metal silicate solution to a solution of an aluminium salt which is initially at a pH below 4 until the pH of the resulting mixture is approximately 4, thereby to induce some precipitation and to form a sol; b) gradually adding alkali to said sol to raise the pH to approximately 7, thereby to induce further precipitation and gel the sol or further gel the sol, said gelled sol being a hydrated silica/hydrated alumina composite: c) separating the gel from the aqueous medium and washing the resulting product to remove dissolved salts; and d) drying the washed product and reducing it in particle size. This colour developing material is then formulated into a coating composition, applied to a paper base and dried to produce a colour developing record material as used in pressure-sensitive (carbonless) copying paper sets.
