Patent ID: 7198667

Claim:
A solid pigment preparation comprising: (A) from 60% to 85% by weight of at least one organic pigment, (B) from 0.1% to 15% by weight of at least one pigment derivative of the general formula I where P is a core structure of an organic pigment selected from the group consisting of quinophthalone and phthalocyanine pigments; T 1 and T 2 are independently a chemical bond, —CONR 1 — or —SO 2 NR 1 —; B 1 and B 2 are independently a chemical bond, C 1 –C 8 -alkylene or phenylene; X and Y independently represent identical or different groups —SO 3 − Ka + or —COO − Ka + ; m and n are each a rational number from 0 to 3 subject to the proviso that 1≦m+n≦4; Ka + is H + , Li + , Na + , K + , N + R 2 R 3 R 4 R 5 or a mixture thereof; R 1 is hydrogen; C 1 –C 4 -alkyl; unsubstituted or C 1 –C 18 -alkyl-substituted phenyl; or unsubstituted or C 1 –C 18 -alkyl-substituted naphthyl; R 2 , R 3 , R 4 and R 5 are independently hydrogen; C 1 –C 30 -alkyl; C 3 –C 30 -alkenyl; C 5 –C 6 -cycloalkyl, unsubstituted or C 1 –C 24 -alkyl-substituted; unsubstituted or C 1 –C 24 -alkyl- or C 2 –C 24 -alkenyl-substituted phenyl; unsubstituted or C 1 –C 24 -alkyl- or C 2 –C 24 -alkenyl-substituted naphthyl; a radical of the formula —[CHR 6 —CHR 7 —O] x —R 8 where the repeat units —[CHR 6 —CHR 7 —O] can vary for x >1; R 6 , R 7 and R 8 are independently hydrogen or C 1 –C 6 -alkyl; x is an integer ≧1, and (C) from 14.9% by weight to 39.9% by weight of at least one surface-active additive selected from the group consisting of the nonionic polyethers comprising no primary amino group, said polyethers' acidic phosphoric, phosphonic, sulfuric and/or sulfonic esters, the salts of these esters, and alkyl- and alkylarylsulfonic acids, the salts of these acids and their condensation products with formaldehyde.
