摘要
The invention relates to novel fine-particle pigment preparations comprising fine-particle C.I. Pigment Blue 15:6 as a base pigment and pigment dispersants of formula (II) wherein CPC is a radical of a copper phthalocyanine, n is a number between 0.1 and 4, preferably between 0.2 and 2; m is a number between 0.1 and 4, preferably 0.2 and 2; Kat is a cation from the group of alkali metals or H+; o is a number between 0 and 3.9, preferably between 0 and 1.8; and n = m+o; and R1, R2, R3, R4 independently represent hydrogen or a radical from the group comprising C1-C20 alkyl, C2-C20 alkenyl, C5-C20 cycloalkyl, C5-C20 cycloalkenyl, C1-C4 alkylphenyl, the previously cited radicals being optionally branched and optionally substituted by sulf-, carboxy, hydroxy and halogen, with the proviso that one, two or three of the radicals R1 to R4 is/are hydrogen. The invention also relates to the method for producing said pigment preparations.
