Abstract
A polymerizable liquid crystal composition excellent in storage stability and UV curing property and a polymer thereof are provided. The polymerizable liquid crystal composition contains a compound represented by formula (1) as a component (A), an optically active compound represented by formula (2) as a component (B), and a mixture of a photopolymerization initiator and a photosensitizer as a component (C), and a ratio of the component (A) is from 77 to 98% by weight, a ratio of the component (B) is from 1 to 15% by weight, and a ratio of the component (C) is from 1 to 8% by weight, based on a total weight of the composition:wherein Z independently represents a single bond or alkylene having from 1 to 10 carbon atoms; Y1 independently represents a single bond or —O—; R1 represents methyl or ethyl; A1 and A2 each independently represents 1,4-phenylene or 4,4′-biphenylene; Y2 represents —COO— or —OCO—; Q represents a single bond or oxyalkylene having from 1 to 10 carbon atoms; and p represents 0 or 1.
