WIPO Patent Application WO/2015/098775
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an optical resin composition having excellent transparency and being extremely low in both orientation birefringence and photoelastic birefringence even in a thick molded article such as an injection-molded article, as well as having excellent heat resistance or mechanical characteristics such as impact resistance including Izod strength; and a molded article of the optical resin composition, particularly an injection-molded article. An optical resin composition containing a thermoplastic resin and a polymer containing a crosslinked structure, the photoelastic constant of the polymer containing a crosslinked structure having the opposite sign from the photoelastic constant of the thermoplastic resin, and the haze of a molded article having a thickness of 2 mm being 6% or less.
