摘要： The present invention provides a compound represented by the general formula (I), and a polymerizable composition containing the compound. When the polymerizable composition containing the compound represented by the formula (I) is used to form a filmy product, the resulting filmy product exhibits less change over time in phase difference and reverse wavelength dispersion and when the filmy polymer is irradiated with UV light, peeling from a substrate is unlikely to be caused. Further, the invention provides a polymer obtained through polymerization of the polymerizable composition and an optically anisotropic body obtained using the polymer.

摘要： 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.
