Document Type and Number:
WIPO Patent Application WO/2017/203852
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an optical use polycarbonate resin composition which exhibits good fluidity, has a high refractive index, is inexpensive and exhibits impact resistance. This problem can be solved by an optical use polycarbonate resin composition that contains a polycarbonate resin (A) which contains a constituent unit represented by formula (1) and has an intrinsic viscosity of 0.320-0.630 dL/g, and polycarbonate resin (B) which contains a constituent unit represented by formula (2) and has an intrinsic viscosity of 0.320-0.600 dL/g, wherein the polycarbonate resin that contains a constituent unit represented by formula (2) is contained at a proportion of 45-75 mass%.
