HEAT-RESISTANT RESIN COMPOSITION CONTAINING BLENDED COLORANT HAVING EXCELLENT THERMAL STABILITY

摘要

PURPOSE:To obtain the titled composition having excellent thermal stability as well as extremely low degree of thermal discoloration at high temperatures, by blending a resin composition consisting of a resin containing imide groups, etc., with a specific amount of a specific colorant. CONSTITUTION:A composition obtained by blending 100pts.wt. resin composition consisting of (A) a resin containing imide groups in side chains or (B) the composition (A) and other thermoplastic resins and/or elastomers, e.g. polystyrene, maleic anhydride-styrene copolymer, etc., with (C) a colorant of C.I. Pigment Red 149 and, if necessary, (D) 0.0001-30pts.wt. one or more colorants selected from C.I. Pigment Red 101, C.I. Pigment Yellow 37, C.I. Pigment Blue 15, etc.
