ABSTRACT:
Solid pigment preparations containing the following ingredients as substantial components: (A) 60–85 wt. % of at least one organic pigment, (B) 0.1–15 wt. % of at least one pigment derivative of general formula I wherein the variables have the following meanings: P is the radical of the parent substance of an organic pigment; T1, T2independently represent a chemical bond, —CONR1— or —SO2NR1—; B1, B2independently represent a chemical bond, C1–C8-alkylene or phenylene; X, Y independently represent similar or different groups —SO3— Ka+or —COO— Ka+; m, n represent a rational number from 0 to 3, whereby 1=m+n=4; Ka+H+, Li+, Na+, K+, N+R2R3R4R5or a mixture of said cations; R1represents hydrogen; C1–C4-alkyl; phenyl or naphthyl which can be respectively substituted by C1–C18-alkyl; R2, R3, R4, R5independently represent hydrogen; C1–C30-alkyl; C3–C30-alkenyl; C5–C6-cycloalkyl which can be substituted by C1–C24-alkyl; phenyl or naphthyl which can be respectively substituted by C1–C24-alkyl or C2–C24-alkenyl; a radical of formula —[CHR6—CHR7—O]x—R8, wherein the repeating units —[CHR6—CHR7—O] for x >1 can vary; R6, R7, R8independently represent hydrogen or C1–C6-alkyl; x is a whole number =1, and (C) 14.9 39.9 wt. % of at least one surface active additive from the group of non-ionic polyethers containing no primary amino groups, the acidic phosphoric acid esters, phosphonic acid esters, sulphuric acid esters and/or sulfonic acid esters thereof, the salts thereof and the condensation produces thereof with formaldehyde.
