The infrared ray transmitted filter null which was formed from the infrared ray permeable resin composition and this resin composition

摘要

PURPOSE: To obtain an infrared-transmitting resin composition and an infrared- transmitting filter which consist mainly of an aromatic polycarbonate resin excellent in flowability, heat resistance, impact resistance, frictional and wearing resistance, and infrared transmission. ;CONSTITUTION: This composition consists substantially of 100 pts.wt. aromatic polycarbonate resin (A) and 0.03-1.0 pt.wt. dyes (B) consisting of an anthraquinone green dye (b-1), a perinone red dye (b-2), and quinophthalone yellow dye (b-3). It is characterized in that the weight ratio of (b-1)/(b-2)/(b-3) is (20-35)/(40-60)/(0.1-3).;COPYRIGHT: (C)1997,JPO
