A pigment preparation comprising C.I. Pigment Yellowof formula (I) as base pigment and C.I. Pigment Yellowof formula (II) as pigment dispersant. 

Monoazo pigment preparations based on C.I. Pigment Yellow 74

The invention relates to the use of a pigment composition containing between 86.0 and 99.9 total mol % of C.I. Pigment Yellow 74 molecules and between 14.0 and 0.1 total mol % of at least one monoazo pigment of the formula (1) wherein Rrepresents Cl, OCH, OHor NOas a coloring agent for pigmenting ink-jet inks and color filters.

Use of a pigment composition comprising mixed crystals based on CI pigment yellow 74

The invention relates to the use of pigment preparations comprising C.I. Pigment Yellow 74 as base pigment and one or more pigment dispersants of the formula (I) wherein

Use of a pigment preparation based on C.I. pigment yellow 74

A method for the production of a diazo pigment, or a mixture of diazo pigments, according to formula (I) of the specification by azo coupling, wherein the azo coupling product is subjected to a finish in an organic solvent or in an agueous organic solvent with a neutral or alkaline pH.

Method for producing disazo pigments

The invention relates to a powdery dye composition consisting essentially of C.I. Pigment Red 170 (C.I. No. 12475) and barium sulfate, wherein the barium sulfate is added before or during the production process of the C.I. Pigment Red 170. The inventive addition of barium sulfate enables non-homogeneities and caking to be avoided in the mixture.

Dye composition for dyeing powder coatings

The invention provides novel pigment dispersants of the formula (I):in which Q is a radical of the formula (Ia):

Pigment dispersants based on diketopyrrolopyrrole compounds and pigment preparations

The invention provides novel pigment dispersants of the formula (I)in which Q is a radical of the formula (Ia)

The invention provides novel pigment dispersants of the formula (I)in which is a radical of the formula (Ia)s is a number from 0.1 to 4.0 andn is a number from 0 to 2.0;and provides pigment preparations comprising an organic base pigment and a pigment dispersant of the formula (I).

Diketopyrrolopyrroles of the formula (I):wherein

Diketopyrrolopyrrole pigments

This invention relates to azo pigments of general formula (I) wherein D represents the radical of a diazo component; Rand Rare the same or different and represent hydrogen, a C-Calkyl radical which is optionally substituted by hydroxy, amino, halogen or methoxy, or a (C-C) aryl radical which is optionally substituted by one, two or three substituents from the group C-Calkyl, C-Calkoxy, F, Cl, Br, CF, NO, OH, CONH, CONH(C-Calkyl), CON(C-Calkyl), COO(C-Calkyl), SONH, SONH(C-Calkyl) and SON(C-Calkyl), provided that Rand Rdo not simultaneously represent hydrogen; Rrepresents hydrogen, C-Calkyl, halogen, trifluoromethyl, C-Calkoxy, NO, or CN; and n represents 1, 2 or 3
