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.
