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, T² independently represent a chemical bond, —CONR¹— or —SO₂NR¹—; B¹, B² independently 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⁺R²R³ R⁴ R⁵ or a mixture of said cations; R¹ represents hydrogen; C₁–C₄-alkyl; phenyl or naphthyl which can be respectively substituted by C₁–C₁₈-alkyl; R², R³, R⁴, R⁵ independently 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, R⁸ independently 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.

Claims

1. 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

2. The solid pigment preparation as claimed in claim 1 in the form of granules having an average particle size from 50 to 5 000 μ

m and a BET surface area of ≦

15 m²/g.

3. The solid pigment preparation as claimed in claim 1, wherein component (C) is at least one additive selected from the group consisting of the alkylene oxide copolymers, the reaction products of alkylene oxides with alcohols, amines, aliphatic carboxylic acids or carboxamides, the acidic phosphoric, phosphonic, sulfuric and sulfonic esters of these alkylene oxide compounds, the salts of these esters, and alkylphenyl- and alkylnaphthalenesulfonic acids, the salts of these acids and their condensation products with formaldehyde.

4. A process for producing pigment preparations as claimed in claim 1, comprising wet-comminuting the pigment (A) in aqueous suspension which comprises additive (C) and, optionally, pigment derivative (B) and also, optionally prior or subsequent neutralization of the suspension with a base and then drying the suspension, after the rest of pigment derivative (B) and additive (C) has been added.

5. A process for coloration of macromolecular organic and inorganic materials, comprising incorporating pigment preparations as claimed in claim 1 in these materials by stirring or shaking.

6. The process as claimed in claim 5 for coloration of coatings, paints, inks, and finish systems, comprising a liquid phase, wherein the liquid phase comprises water, organic solvents or mixtures of water and organic solvents.

7. A process for coloration of macromolecular organic and inorganic materials with color-mixing systems, comprising utilizing pigment preparations as claimed in claim 1 as mixing components.

8. A process for coloration of plastics, comprising incorporating pigment preparations as claimed in claim 1 in the plastics by extruding, rolling, kneading or milling.
