Process to lower the viscosity of coating solutions for the production of light-sensitive reproduction materials

摘要

Process for lowering the viscosity of coating solutions containing a thixotropy-causing filler for the production of light-sensitive reproduction materials by adding at least one compound corresponding to one of the following formulas: (a) (b) or (c) wherein R is a linear saturated or unsaturated hydrocarbon chain having 2 to 12 carbon atoms, optionally substituted in which one or more carbon atoms can be replaced by N(R5), O, S, and/or an aromatic radial, or a 5 to 8 membered aliphatic ring. R1 to R4 are H, alkyl, aryl, and aralkyl, whereby R1 to R4 can be the same or different; R5 is R1 to R4; R6 and R7 are R1 to R4, -(CHR8)p-OH; p is 1 to 6; q and r are 1 to 6 and can be the same or different; R8 is H, alkyl; R9 and R10 are H, alkyl, -(CHR8)p-OH.
