Patent ID: 8680188

Claim:
A solid pigment preparation comprising (a) 5% to 99% by weight of at least one pigment, (b) 1% to 95% by weight of a copolymer consisting of the following structural units: 0 to 20 mol % of structural unit A 0 to 20 mol % of structural unit B 1 to 79 mol % of structural unit C 1 to 79 mol % of structural unit D and 20 to 80 mol % of structural unit E wherein R 1 and R 2 are each independently hydrogen, methyl or methylene, a, b are each zero or one and a+b is one, R 3 is C 8 -C 30 -alkenyl, benzyl or N-propylene imidazole, X and Y are each independently —OH, —O—C 1 -C 30 -alkyl, NR 4 R 5 or —O − N + H 2 R 4 R 5 , R 4 and R 5 are each independently hydrogen, R 3 or R, R is Z is C 2 -C 4 -alkylene, n is a number between 1 and 1000, R 6 is hydrogen, C 1 -C 30 -alkyl, C 5 -C 12 -cycloalkyl or C 6 -C 30 -aryl, R 7 is hydrogen or C 1 -C 4 -alkyl, R 8 is hydrogen or C 1 -C 4 -alkyl, and R 9 is C 1 -C 60 -alkyl or C 6 -C 10 -aryl; and (c) 0 to 10% by weight of an auxiliary selected from the group consisting of fillers, flame retardants, preservatives, photoprotectants, pigmentary dispersants, nonpigmentary dispersants, surfactants, antioxidants, defoamers, resins, antistats, each based on the total weight of the pigment preparation.
