ABSTRACT:
A composition comprising a polymerizable compound of the formula (1) and a rod-shaped polymerizable liquid crystal compound:in-line-formulae description="In-line Formulae" end="lead"?P2-E2-X2-B2-A2-(G2)t-Y-(G1)s-A1-B1-X1-E1-P1  (1)in-line-formulae description="In-line Formulae" end="tail"?(in the formula (1), Y represents a di-valent group, s and t represent each independently an integer of 0 or 1, G1 and G2 when s and t are 1 represent each independently —CR1R2—, R1and R2represent each independently an alkyl group having 1 to 4 carbon atoms, halogen atom or hydrogen atom, A1 and A2 represent each independently a di-valent cyclic hydrocarbon group, di-valent heterocyclic group, methylenephenylene group, oxyphenylene group or thiophenylene group, B1 and B2 represent each independently a di-valent group, X1 and X2 represent each independently a di-valent group, E1 and E2 represent each independently an alkylene group having 2 to 25 carbon atoms, and P1 and P2 represent a hydrogen atom or polymerizable group, at least one of P1 and P2 being a polymerizable group.).
