The present invention aims to provide a polymerizable compound that has high storage stability without causing crystal precipitation when added to a polymerizable composition and to provide a polymerizable composition containing the polymerizable compound. A polymer film produced by polymerization of the polymerizable composition has a low haze, high thickness uniformity, low occurrence of nonuniform orientation, high surface hardness, high adhesiveness, and good appearances and fewer orientation defects even after ultraviolet irradiation. The present invention also aims to provide a polymer produced by polymerization of the polymerizable composition and an optically anisotropic body produced from the polymer.

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.

The present invention provides a polymerizable composition containing a polymerizable liquid crystal compound represented by Formula (I) and an oxime compound,
