摘要： Provided is an aromatic polycarbonate resin composition which comprises 100 parts by mass of an aromatic polycarbonate resin and from 0.001 to 1 part by mass of an additional thermoplastic resin that differs from the aromatic polycarbonate resin in the refractive index by at least 0.001 and which is so designed that the ratio (X)/(Y) is at least 0.5 wherein (X) indicates the spectral transmittance at 320 nm through a sample plate of the resin composition having a thickness of 2 mm and (Y) indicates the spectral transmittance at 633 nm through it. Having realized further increase in the transparency of aromatic polycarbonate resin, the resin composition gives moldings of which the transparency is comparable to that of acrylic resin for optical use, and the resin moldings have good impact resistance and heat resistance.
