ABSTRACT:
A near infrared absorbent polycarbonate resin composition comprising a polycarbonate resin and a diimmonium type near infrared absorber. In this resin composition, not only the diimmonium type near infrared absorber shows a near infrared absorptivity but also its thermal stability is improved; therefore, the resin composition can be used in such applications as the heat resistance of near infrared absorbent material is required, and can withstand long-term use as compared with conventional near infrared absorbent materials containing a diimmonium type near infrared absorber.
