Document Type and Number:
WIPO Patent Application WO/2017/188366
Kind Code:
A1
Abstract:
Provided are a novel polymer composition for obtaining a liquid crystal alignment film, a liquid crystal alignment film which uses the same, and a novel monomer. The present invention provides a polymer composition containing (A) a photosensitive-side-chain-type polymer exhibiting liquid crystal properties in a predetermined temperature range, and (B) an organic solvent, wherein the polymer composition is characterized in that a resin as component (A) contains a side chain represented by formula (a). (In formula (a): L is a C1-16 straight-chain or branched-chain alkylene; X represents CH2-CH2, CH=CH, or C≡C; Y1 each independently represents a phenylene group or the like; Y2 represents –COOH, -CR3=CR4-COOH, -CR5=CR6-CO-O-Y3, or –O-CO-CR5=CR6-Y3; R3, R4, R5, and R6 each independently represents a hydrogen atom or a methyl group, and Y3 represents a phenyl group or the like.)
