Anthraquinone compound-containing liquid crystal composition for controlling light, photocured product thereof, and light-controlling element

Abstract

The present invention pertains to: a liquid crystal composition for controlling light that contains, as a dichroic dye, an anthraquinone compound having a specific structure; and a light-controlling element that contains a cured product of said liquid crystal composition for controlling light and exhibits excellent contrast, light-blocking performance, lightfastness, and heat tolerance during current supply. More specifically, the present invention pertains to: a liquid crystal composition for controlling light that contains a compound represented by formula (A) (in the formula, R1 represents a C4-12 alkyl group or a C4-12 alkoxy group, and each R2 independently represents a C6-12 alkyl group), a liquid crystal material, a photocurable compound, and a photoinitiator; and a light-controlling element that is formed by sandwiching a photocured product of said composition between a pair of substrates.
