Solid pigment preparations containing pigment derivatives and surface-active additives

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; T, Tindependently represent a chemical bond, —CONR— or —SONR—; B, Bindependently represent a chemical bond, C1–C8-alkylene or phenylene; X, Y independently represent similar or different groups —SO— Kaor —COO— Ka; m, n represent a rational number from 0 to 3, whereby 1=m+n=4; KaH, Li, Na, K, NRRRRor a mixture of said cations; Rrepresents hydrogen; C–C-alkyl; phenyl or naphthyl which can be respectively substituted by C–C-alkyl; R, R, R, Rindependently represent hydrogen; C–C-alkyl; C–C-alkenyl; C–C-cycloalkyl which can be substituted by C–C-alkyl; phenyl or naphthyl which can be respectively substituted by C–C-alkyl or C–C-alkenyl; a radical of formula —[CHR—CHR—O]x—R, wherein the repeating units —[CHR—CHR—O] for x >1 can vary; R, R, Rindependently represent hydrogen or C–C-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.
