Patent ID: 8796366

Claim:
A solid pigment preparation comprising (A) from 5% to 99% by weight of at least one pigment other than C.I. Pigment Blue 15:3, (B) from 1% to 95% by weight of at least one water-soluble dispersing additive based on copolymers consisting of the following structural units: (i) from 1.0 to 50 mol % of structural unit B1 (ii) from 50 to 99.0 mol % of structural units B2 and B3 in a total whereof from 0 to 100 mol % of said structural unit B2 and from 0 to 100 mol % of said structural unit B3 can be present, (iii) from 0 to 49 mol % of structural unit B4 where R 1 , R 4 , R 6 and R 8 are each independently hydrogen or C 1 -C 4 -alkyl, R 2 is a covalent bond, C 1 -C 4 -alkylene, C 1 -C 4 -alkylene-C 6 -C 12 -arylene, C 6 -C 30 -arylene or the radical R 3 is hydrogen, Na + , K + or N(R 1 ) 4 + , R 5 and R 7 are each independently C 1 -C 40 -alkyl, C 5 -C 30 -cycloalkyl, C 1 -C 4 -alkylene-C 6 -C 12 -aryl or C 6 -C 30 -aryl, and R 9 is hydrogen, C 1 -C 40 -alkyl, C 5 -C 30 -cycloalkyl, C 6 -C 30 -aryl, C 1 -C 4 -alkylene-C 6 -C 12 -arylene, —F, —Cl, —Br, —OH or —CN, and wherein the aryl optionally substituted with C1-C4-alkyl; (C) from 0% to 30% by weight of an auxiliary selected from the group consisting of fillers, flame retardants, preservatives, photoprotectants, pigmentary dispersants, nonpigmentary dispersants, surfactants, antioxidants, defoamers, resins and antistats, all based on the total weight of the pigment preparation, and wherein the sulfonate group content of (B1) is greater than 1 μmol and less than 100 μmol per gram of solid pigment preparation.
