  The present invention provides a polymerizable compound having high storage stability without causing crystal precipitation when added to a polymerizable composition. The present invention also provides a polymerizable composition containing the compound. When the filmy polymer produced through polymerization of the polymerizable composition is irradiated with UV light, it hardly discolors or peels from substrate. Further, the present invention provides a polymer produced through polymerization of the polymerizable composition and an optically anisotropic body using the polymer.

  3-benzodithioles as candidates for new electron donors. The oxidation potential of monosilyl-substituted 1,3-benzodithiole was found to be significantly less positive than that of the parent 1,3-benzodithiole. The introduction of the second silyl group caused further decrease of the oxidation potential. Compounds composed of two 1,3-benzodithiole units linked by a silyl group were also synthesized. These

  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.
