PURPOSE:To provide a colorant for resins, which exhibits excellent solubility in resins, Gas excellent resistance to migration and gives colored moldings which are transparent and excellent in resistance to light, heat and chemicals, consisting of a triazine compd. contg. a dye residue. CONSTITUTION:A colorant for resins consists of a compd. of formula I (wherein D is a residue of a condensed polycyclic dye; A is alkyl, allyl; m is 0, 1; X is O, NH; R<1>, R<2> are each -NR<3>R<4>, -OR<5>; R<3>, R<4>, R<5> are each H, alkyl, cyanoalkyl, hydroxyalkyl, alkenyl, aryl, aralkyl, etc.; R<3>, R<4> may form a five- or six- membered nitrogen-contg. heterocyclic ring when combined together) such as compds. of formulas II and III (wherein Cy is a group of formula IV). The colorant exhibits excellent solubility in thermoplastic resins such as PS, PVC and polymethyl methacrylate, has excellent migration resistance and gives colored moldings which are transparent and excellent in resistance to light, heat and chemicals.
