US 2017/0362508 A1 · POLYMERIZABLE COMPOUND AND OPTICALLY ANISOTROPIC BODY

Abstract

A problem of the present invention is to provide a polymerizable compound and a polymerizable composition which cause little decrease in retardation and discoloration when a film-shaped polymer produced by polymerization is irradiated with ultraviolet/visible light for a long time at high temperature. A further problem is to provide a polymer produced by polymerizing the polymerizable composition and an optically anisotropic body using the polymer. As a result, a compound useful as a component of a polymerizable composition was obtained. An optically anisotropic body using a polymerizable liquid crystal composition containing the compound of the present invention is useful for application to an optical film and the like.
