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.

Polymerizable compound and optically anisotropic object

There is provided a polymerizable composition, by which discoloration or alignment defects are less likely to occur when a filmy polymer, which is obtained by adding a polymerizable compound to the polymerizable composition and polymerizing this composition, is irradiated with ultraviolet light. There are also provided a polymer obtained by polymerizing the polymerizable composition, and an optically anisotropic body using the polymer. The present invention provides a polymerizable low-wavelength dispersive or polymerizable reverse-wavelength dispersive compound having a partial structure represented by Formula (Z-0). Further, the present invention provides a composition containing the compound; a polymer obtained by polymerizing the composition; and an optically anisotropic body obtained by using the polymer. 

Polymerizable compound and optically anisotropic body

In light of requests to reduce or reverse the wavelength dispersion of the birefringence of a phase-retardation film in order to increase the viewing angle of a liquid crystal display, the present invention provides a polymerizable compound that reduces, for example, the likelihood of crystals precipitating in a polymerizable composition including the polymerizable compound and enables the polymerizable composition to have high preservation stability and a polymerizable composition including the polymerizable compound which reduces the likelihood of inconsistencies being formed in a film-like polymer produced by polymerizing the polymerizable composition. Another object of the present invention is to provide a polymer produced by polymerizing the polymerizable composition and an optically anisotropic body including the polymer.

It is an object of the present invention to provide a polymerizable compound having a good liquid crystal property, a good alignment property, sufficient solubility in solvents, high preservation stability in a solution state, and high optical stability; a composition including the polymerizable compound; a polymer produced by polymerizing the polymerizable compound, such as a resin produced using the polymerizable compound; an optically anisotropic body including the polymer; and a liquid crystal display element and an organic EL device that include the optically anisotropic body. As a result of conducting intensive studies in order to achieve the above object, the compound represented by General Formula (I) is developed.
