Abstract:
The present invention relates to: a polymerizable compound represented by a formula (I); a polymerizable composition comprising the polymerizable compound and an initiator; a polymer obtained by polymerizing the polymerizable compound or the polymerizable composition; and an optically anisotropic article comprising the polymer [in the formula, Y1 to Y8 are a chemical single bond, —O—, —O—C(═O)—, —C(═O)—O—, or the like; G1 and G2 are a divalent aliphatic group having 1 to 20 carbon atoms, or the like; Z1 and Z2 are an alkenyl group having 2 to 10 carbon atoms, or the like; A1 is a tetravalent aromatic group, or the like; A2 and A3 are a divalent alicyclic hydrocarbon group having 3 to 30 carbon atoms, or the like; A4 and A5 are a divalent aromatic group having 4 to 30 carbon atoms, or the like; Ax1 and Ax2 are an organic group having 2 to 30 carbon atoms that includes an aromatic ring, or the like; Ay1 and Ay2 are a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or the like; Q1 and Q2 are a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or the like; and m and n are 0 or 1]. According to the present invention, a polymerizable compound, a polymerizable composition, and a polymer that have a practical low melting point, exhibit excellent solubility in a general-purpose solvent, can be produced at low cost, and can produce an optical film that achieves uniform conversion of polarized light over a wide wavelength band, and also provide an optically anisotropic article.
