Document Type and Number:
WIPO Patent Application WO/2016/171194
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a film that absorbs specific ultraviolet radiation and does not undergo roll staining or bleed out by using a specific polycarbonate resin and a polycarbonate resin that contains a specific ultraviolet radiation absorber. The present invention relates to a polycarbonate resin film comprising: a polycarbonate resin composition that contains 100 parts by weight of a polycarbonate resin which contains structural units derived from a dihydroxy compound represented by formula (1); and more than 0.45 parts by weight but not more than 7 parts by weight, relative to 100 parts by weight of the polycarbonate resin, of an ultraviolet radiation absorber having a melting point of not less than 135ºC but less than 300ºC and a 5% weight loss temperature of greater than 240ºC. The light transmittance of the film at a wavelength of 380 nm is 0.001-15%, and the thickness of the film is 5-120 μm.
