A pigment composition is provided comprising (a) an organic pigment and (b) an adduct containing a compound of formula (I) or a tautomeric form thereof, wherein X is O or S; Y is O, S or NR 1 ; the group -A-B— is selected from the group consisting of —CR 2 ═CR 3 —, —CR 4 R 5 —CR 6 R 7 — —CY—CR 8 R 9 —, —CX—NR 10 —, —CR 11 ═N—, —CR 12 R 13 —NR 14 — and R 1 is hydrogen, C 1 -C 8 alkyl, C 3 -C 7 cycloalkyl, C 6 -C 10 aryl or C 7 -C 10 aralkyl; R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , R 13 and R 14 are independently of each other hydrogen, halogen, C 1 -C 8 alkyl, C 2 -C 8 alkenyl or C 6 -C 10 aryl, or R 2 and R 3 form a benzoannellated ring; and/or a melamine- or pyrimidine-based compound, which is optionally substituted. The pigment composition may be used as colorant in various applications, especially in coloring high molecular weight organic material, for example, coating compositions, paints, printing inks, liquid inks, plastics, films or fibers. |
