Optical Compensatory Film, Process for Producing the Same, and Polarizing Plate and Liquid Crystal Display Employing the Same
摘要：
A novel optical compensatory sheet comprising an optically anisotropic layer comprising at least one liquid crystal compound, at least one cellulose ester, and at least one polymer A comprising at least one repeating unit derived from a monomer having a fluoro-aliphatic group, and at least one repeating unit having a group selected from the group consisting of carboxyl group (—COOH) or a salt thereof, a sulfo group (—SO3H) or a salt thereof and a phosphonoxy group {—OP(═O) (OH)2} or a salt thereof, is disclosed. A novel optical compensatory sheet comprising an optically anisotropic layer comprising at lest one liquid crystal compound at least one polymer C, having a weight average molecular weight of not less than 5000 and less than 20000, represented by a formula (1b), and at least one polymer D, having a weight average molecular weight of not less than 20000, represented by a formula (1b), is also disclosed. In the formula, “A” represents a repeating unit having a group capable of hydrogen bonding, “B” represents a repeating unit having a polymerizable group, and “C” represents a repeating unit derived from an ethylene-type unsaturated monomer. -(A)ai-(B)bj-(C)ck-   Formula (1b)
