PIGMENTARY FORMULATIONS ON THE BASE OF DICETOPIRROLOPIROL PIGMENTS WITH PIGMENTARY DISPERSIVE AGENTS OF BASIC CHARACTER.

摘要

Pigment formulation, characterized by a content of: a) at least one diketopyrrolopyrrole pigment or a mixed crystal containing a diketopyrrolopyrrole pigment, and b) at least one pigmentary dispersing agent of the ** formula **, in which the two radicals Z are the same or different, and Z has the meaning of Z3 or Z4, with the proviso that both radicals Z do not mean simultaneously Z4, and in which Z3 is a radical of the formula (Ic), in which that R2 and R3 are the same or different and represent a hydrogen atom, a substituted or unsubstituted alkyl group, or partially fluorinated or perfluorinated, with 1 to 20 carbon atoms, or a substituted or unsubstituted alkenyl group, or partially fluorinated or perfluorinated, with 2 to 20 carbon atoms, the substituents may be hydroxy, phenyl, cyano, chloro, bromine, C2-C4 acyl or C1-C4 alkoxy, or R2 and R3 in common with the N atom, form a saturated, unsaturated heterocyclic ring or o aromatic, which eventually contains another nitrogen, oxygen or sulfur atom in the ring; and X means a branched or unbranched C2-C6 alkylene radical, or a C5-C7 cycloalkylene radical, which may be substituted with 1 to 4 C1-C4 alkyl radicals, hydroxy radicals, hydroxyalkyl radicals with 1 to 4 atoms of carbon and / or with 1 to 2 additional C5-C7 cycloalkyl radicals; Z4 is hydrogen, hydroxy, amino, phenyl, (C1-C4 alkyl) -phenyl or C1-C20 alkyl, the phenyl ring and the alkyl group may be substituted with one or more substituents selected from the group consisting of Cl, Br, CN, OH, C6H5, carbamoyl, C2-C4 acyl and C1-C4 alkoxy, the phenyl ring may also be substituted with NR2R3, or the alkyl group is perfluorinated or partially fluorinated.
