Abstract:
A polycarbonate resin composition capable of suppressing the deterioration of the weather resistance of the infrared shielding material fine particles, including: a composite tungsten oxide fine particle (A), a weather resistance improver (B), and a polycarbonate resin (C), wherein (A) is expressed by a general formula MxWOy, and (B) is any one of those containing a phosphite compound (B1), or containing the phosphite compound and one or more kinds selected from a hindered phenol-based stabilizer, phosphoric acid-based stabilizer and sulfur-based stabilizer (B2), or containing a hindered phenol-based stabilizer and one or more kinds selected from a phosphoric acid-based stabilizer and sulfur-based stabilizer (B3), and an addition amount of (B) is 0.1 parts by weight or more and 20 parts by weight or less, based on 1 parts by weight of (A), and provides a heat ray shielding molded body and a heat ray shielding lamination body produced using the composition.
