Pigment formulations and processes for their preparation

Claim 1

A pigment formulation comprising a) 99.5 to 80% by weight of at least one organic pigment selected from the group consisting of perylene pigments, perinone pigments, quinacridone pigments, azo pigments, benzimidazolone pigments, anthraquinone pigments and anthanthrone pigments, and b) 0.5 to 20% by weight of at least one pigment-dispersing agent having a formula ##STR12## in which R 1 is a hydrogen atom, hydroxyl, amino or an alkyl group having 1 to 8 carbon atoms, which is optionally substituted by 1 to 4 chlorine or bromine atoms, by a phenyl, cyano, hydroxyl, carbamoyl, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy group, or which is perfluorinated or partly fluorinated; R 2 and R 3 independently of one another are a hydrogen atom, a substituted or unsubstituted or partly fluorinated or perfluorinated alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted or partly fluorinated or perfluorinated alkenyl group having 2 to 20 carbon atoms, it being possible for the substituents to be hydroxyl, phenyl, cyano, chlorine, bromine, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy, or R 2 and R 3 , together with the N atom, form a saturated, unsaturated or aromatic heterocyclic ring, which optionally contains a further nitrogen, oxygen or sulfur atom in the ring; and n is a number from 1 to 6.

Claim 14

A method of pigmenting high molecular weight organic materials of natural or synthetic origin in a form selected from the group consisting of plastic compositions, melts, spinning solutions, coatings, paints, toners and printing inks, comprising the step of adding a pigment formulation to said materials wherein said pigment formulation comprises a) 99.5 to 80% by weight of at least one organic pigment selected from the group consisting of perylene pigments, perinone pigments, quinacridone pigments, azo pigments, benzimidazolone pigments, anthraquinone pigments and anthanthrone pigments, and b) 0.5 to 20% by weight of at least one pigment-dispersing agent having a formula ##STR16## in which R 1 is a hydrogen atom, hydroxyl, amino or an alkyl group having 1 to 8 carbon atoms, which is optionally substituted by 1 to 4 chlorine or bromine atoms, by a phenyl, cyano, hydroxyl, carbamoyl, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy group, or which is perfluorinated or partly fluorinated; R 2 and R 3 independently of one another are a hydrogen atom, a substituted or unsubstituted or partly fluorinated or perfluorinated alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted or partly fluorinated or perfluorinated alkenyl group having 2 to 20 carbon atoms, it being possible for the substituents to be hydroxyl, phenyl, cyano, chlorine, bromine, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy, or R 2 and R 3 , together with the N atom, form a saturated, unsaturated or aromatic heterocyclic ring, which optionally contains a further nitrogen, oxygen or sulfur atom in the ring; and n is a number from 1 to 6.

Claim 15

A method of pigmenting high molecular weight organic materials of natural or synthetic origin in a form selected from the group consisting of plastic compositions, melts, spinning solutions, coatings, paints, toners and printing inks, comprising the step of adding a pigment formulation to said materials wherein said pigment formulation comprises a) 99.5 to 80% by weight of at least one organic pigment selected from the group consisting of perylene pigments, perinone pigments, quinacridone pigments, azo pigments, benzimidazolone pigments, anthraquinone pigments and anthanthrone pigments, and b) 0.5 to 20% by weight of at least one pigment-dispersing agent having a formula ##STR16## in which R 1 is a hydrogen atom, hydroxyl, amino or an alkyl group having 1 to 8 carbon atoms, which is optionally substituted by 1 to 4 chlorine or bromine atoms, by a phenyl, cyano, hydroxyl, carbamoyl, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy group, or which is perfluorinated or partly fluorinated; R 2 and R 3 independently of one another are a hydrogen atom, a substituted or unsubstituted or partly fluorinated or perfluorinated alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted or partly fluorinated or perfluorinated alkenyl group having 2 to 20 carbon atoms, it being possible for the substituents to be hydroxyl, phenyl, cyano, chlorine, bromine, C 2 -C 4 -acyl or C 1 -C 4 -alkoxy, or R 2 and R 3 , together with the N atom, form a saturated, unsaturated or aromatic heterocyclic ring, which optionally contains a further nitrogen, oxygen or sulfur atom in the ring; and n is a number from 1 to 6.
