Title:
POLYMERIZABLE COMPOSITION AND OPTICALLY ANISOTROPIC BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/114253
Kind Code:
A1
Abstract:
Provided is a polymerizable composition that contains: a) a polymerizable compound having one or more polymerizable groups and satisfying formula (I): Re(450 nm)/Re(550 nm)<1.0; b) at least one photopolymerization initiator selected from the group consisting of alkylphenone compounds, acylphosphine oxide compounds, and oxime ester compounds; and c) a polymerization inhibitor. Also provided are an optically anisotropic body, a retardation film, an antireflection film, and a liquid crystal display device that are produced using a polymerizable liquid crystal composition of the present invention. The polymerizable composition is useful because the polymerizable composition has excellent solubility and good storage stability, by which deposition of liquid crystals does not occur, and, when a film-shaped polymerized product obtained by polymerizing the polymerizable composition is produced, the polymerized product maintains liquid crystal alignability and has excellent durability, and little unevenness occurs in the coating film surface.
