Title:
RESIN COMPOSITION FOR OPTICAL MATERIAL, OPTICAL FILM, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/046360
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a resin composition which experiences little change in birefringence due to external force, and which is suitable for use in production of an optical member; an optical film obtained using the resin composition; and a liquid crystal display device employing the same. This resin composition for an optical material contains a polycarbonate resin (X), and a polyester resin (Y) represented by the following general formula (1): B-(G-A)n-G-B (1) (wherein B represents a C6-12 aryl monocarboxylic acid residue or a C1-8 aliphatic monocarboxylic acid residue; G represents a C2-12 alkylene glycol residue or a C4-12 oxyalkylene glycol residue; A represents a C2-12 alkylene dicarboxylic acid group or a C6-12 aryl dicarboxylic acid residue, and n is an integer from 0 to 9), and having number-average molecular weight of 200-2,000.
