FILM USING POLYMERIZABLE LIQUID CRYSTAL COMPOSITION CONTAINING PEELING PREVENTIVE AGENT

摘要

A problem is, in a liquid crystal film in which an alignment layer and a liquid crystal composition layer having homogeneous alignment are formed on a support substrate, to improve adhesion between the alignment layer and the liquid crystal composition layer, and durability under a severe environment such as high temperature and high humidity. A solution is a non-liquid crystalline polymerizable compound having a radically polymerizable group and a cationically polymerizable group in a molecule is simultaneously used as an antistripping additive in a polymerizable liquid crystal composition layer having homogeneous alignment.

主权项

1. A film comprising at least an alignment layer and a liquid crystal composition layer in the order on a support substrate,
wherein the liquid crystal composition layer is obtained by immobilizing alignment of a polymerizable liquid crystal compound contained in the polymerizable liquid crystal composition layer, and an alignment state thereof includes homogeneous alignment, and the polymerizable liquid crystal composition layer contains one kind or two or more kinds of antistripping additives having a radically polymerizable group and a cationically polymerizable group in a molecule.
