Abstract
The present invention relates to a polymerizable compound represented by a formula (I). The present invention provides a polymerizable compound, a polymerizable composition, a polymer, and an optically anisotropic article that are capable of obtaining an optical film having a low melting point, having excellent solubility, capable of being manufactured at low cost, and capable of uniform polarized light conversion across a broad wavelength region. [In formula: Yto Yare independently a chemical single bond, —O—, —O—C(═O)—, —C(═O)—O— etc.; Gand Gare independently a divalent C1-C20 aliphatic group etc.; Zand Zare independently C2-C10 alkenyl group that is substituted with a halogen atom etc.; Ais a C2-C30 organic group that includes at least one aromatic ring selected from a group consisting of an aromatic hydrocarbon ring and an aromatic hetero ring; Ais a hydrogen atom, a C1-C20 alkyl group, a C2-C20 alkenyl group, a C3-C12 cycloalkyl group etc.; Ais a trivalent aromatic group etc.; Aand Aare independently a divalent C6-C30 aromatic group etc.; and Qis a hydrogen atom, or a C1-C6 alkyl group etc.]
