Abstract

A composition comprising (A) at least one nickel complex pigment and (B) at least one disperse dye of formula (1) or (2) wherein R 1 is hydrogen, hydroxy or a radical —NHCO—R 6 wherein R 6 is C 1 -C 6 alkyl or unsubstituted or C 1 -C 4 alkyl- or halo-substituted phenyl, R 2 is hydrogen, hydroxy or a radical W—R 7 wherein W is —NHCO— or —S— and R 7 is C 1 -C 6 alkyl or unsubstituted or C 1 -C 4 alkyl- or halo-substituted phenyl, R 3 is hydrogen, R 4 is hydrogen or hydroxy, R 5 is hydrogen, or R 3 and R 4 together form the radical of formula wherein the rings A and B, independently of one another, may carry further substituents, R 8 is hydrogen or —CO—C 2 -C 6 alkyl wherein the C 2 -C 6 alkyl radical may be substituted by carboxy, or a radical wherein R 11 is hydrogen, C 1 -C 4 alkyl, hydroxy, carboxy or halogen, R 12 is hydrogen, C 1 -C 4 alkyl or halogen and R 13 is hydrogen or C 2 -C 3 alkyl or, when R 10 is halogen, R 13 may be methyl, R 9 is hydrogen or halogen, R 10 is hydrogen or halogen, and n is a number 0, 1 or 2, with the proviso that R 9 , R 10 , R 11 , R 12 , and R 13 are not all simultaneously hydrogen, is suitable for the dyeing or printing of semi-synthetic or synthetic hydrophobic fiber materials and in the production of colored plastics or polymeric color particles.
