Abstract

Official abstract text for this publication.

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. Also provided are a polymer produced by polymerizing the polymerizable composition and an optically anisotropic body including the polymer. The present invention provides the compound represented by General Formula (I), a composition including the compound, a polymer produced by polymerizing the composition, and an optically anisotropic body including the polymer.
