Injection molding partially crystalline plastics can be pigmented with distortion producing pigments without distortion of the molded products or alteration of their chemical properties by the use of a colorant combination. The partially crystalline plastics are colored in bulk using a pigment containing at least one CO and one NH group, bonded as CONH or conjugated, and a colorant of formula (I). R1-R4 = H, halogen, R6, OR6 or SR6; R5 = H, linear or branched 1-12C alkyl, benzyl or phenyl; and R6 = an unsubstituted or singly or multiply substituted with halogen, or a 1-6C alkyl apolar group; with the proviso that when R5 = H, R1-R4 = R6 or SR6. Independent claims are also included for: (1) a composition comprising a pigment containing at least one CO and NH group bonded or conjugated as above, and a colorant of formula (I) is used; (2) a compound of formula (III); and (3) a process or composition in which the pigment is of formula (II). R11-R14 = H, R16, OR16 or SR16; R15 = linear or branched 1-12C alkyl, benzyl or phenyl; R16 = unsubstituted, or halogen or O(1-6C alkyl) substituted apolar group; At least one of R11-R14 = R16, OR16 or SR1 and; R7-R10 = H, cyano, carbamoyl, 1-4C alkyl or phenyl. |
