Abstract

Provided are a polymerizable liquid crystal composition, a coating material, a medium, and a polarizing device each produced using a polymerizable liquid crystal compound and a colorant and each capable of producing polarized light suitable for polarizing devices, and also a novel naphtholactam derivative, a novel coumarin derivative, a novel Nile Red derivative, and a novel anthracene derivative each suitable for use as the colorant. Specifically provided are a polymerizable liquid crystal composition containing (A) at least one liquid crystal compound having a polymerizable functional group, (B) at least one colorant, and (C) a polymerization initiator, and a novel naphtholactam derivative of formula (IV′), a novel coumarin derivative of formula (VI′), a novel Nile Red derivative of formula (VII′), and a novel anthracene derivative of formula (VIII′) each suitable for use as the colorant (B).
