Abstract:
A polymerizable composition of the present invention has favorable solubility, and an optically anisotropic body using the polymerizable composition is unlikely to discolor and is excellent in heat resistance and light resistance. The problem to be solved by the present invention is to provide a polymer obtained by polymerizing the polymerizable composition and an optically anisotropic body using the polymer. The present invention relates to a polymerizable composition which includes a compound having at least one mesogenic group and satisfying an expression represented by Expression (1), and which satisfies an expression represented by Expression (2). 0.5≤YI/Δn≤500 Expression (2)
