Abstract

Wäßrige Beschichtung von Durchschreibpapier auf der Basis einer porösen anorganischen Matrix, einem elastifizierend wirkendem organischem Polymer und der in den Poren einge­ schlossenen Farbpaste. Die anorganische Matrix besteht aus einem Zr⁴⁺-Polykondensat oder Zr-Al-Mischoxid-Gel, das vorzugsweise durch Zusatz von alkalilöslichen Polyacrylaten oder Polyvinylacetaten bzw. wasserlöslichen Polyvinylalkoho­ len elastifiziert wird und in den Poren die Farbpaste einge­ schlossen enthält. Zur Herstellung wird eine wäßrige Lösung bzw. Dispersion des Polymeren vorgelegt, unter Zugabe von Ammoniak ein pH von 8 bis 9 eingestellt, und anschließend die Farbpaste und eine wäßrige Lösung der Zr-Verbindung zuge­ mischt. Die Beschichtungsmasse wird in bekannter Weise auf ein Trägermaterial aufgetragen und getrocknet. Aqueous coating of carbonless paper on the base a porous inorganic matrix, an elasticizing acting organic polymer and the in the pores closed color paste. The inorganic matrix exists from a Zr⁴⁺ polycondensate or Zr-Al mixed oxide gel, the preferably by adding alkali-soluble polyacrylates or polyvinyl acetates or water-soluble polyvinyl alcohol len is elasticized and the color paste is inserted into the pores closed contains. An aqueous solution is used for the production or dispersion of the polymer, with the addition of Ammonia adjusted a pH of 8 to 9, and then the Color paste and an aqueous solution of the Zr compound added mixes. The coating composition is applied in a known manner a carrier material is applied and dried.
