BENZIMIDAZOLONE-BASED PIGMENT COMPOSITION AND METHOD FOR PRODUCING COLORED PLASTIC MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a pigment composition comprising C.I. Pigment Yellow 151 and carrying out coloring with excellent heat resistance and to provide a method for producing a colored plastic molded product using the pigment composition. SOLUTION: The benzimidazolone-based pigment composition comprises an aluminum soap (B) in an amount of 0.75-10 pts.mass based on 1 pt.mass of the C.I. Pigment Yellow 151 (A). The method for producing the colored plastic molded product comprises mixing the C.I. Pigment Yellow 151 (A) with the aluminum soap (B) in an amount of 0.75-10 pts.mass based on 1 pt.mass of the C.I. Pigment Yellow 151 (A) and a thermoplastic resin (C) and hot-molding the resultant mixture. COPYRIGHT: (C)2008,JPO&INPIT
