POLYMERIZABLE COMPOSITION CONTAINING POLYMERIZABLE LIQUID CRYSTAL COMPOUND, FILM, AND METHOD FOR PRODUCING FILM
Document Type and Number:
WIPO Patent Application WO/2017/047673
Kind Code:
A1
Abstract:
Provided are: a polymerizable composition that contains a polymerizable liquid crystal compound represented by formula (I) and a urethane(meth)acrylate monomer containing a urethane bond and at least three (meth)acryloyl groups (in the formula, A represents a cyclic divalent group (at least one of which is a divalent saturated hydrocarbon ring group); L represents -C(=O)O-, -OC(=O)-, or the like; m represents an integer from 3 to 12; Sp1 and Sp2 represent alkylene or the like; and Q1 or Q2 represents a polymerizable group); a film containing a layer obtained by curing the polymerizable composition; a film adjacently containing a layer obtained by curing a polymerizable composition containing a polymerizable liquid crystal compound represented by formula (I), and a layer obtained by curing a composition containing a urethane(meth)acrylate monomer; and a method for producing the film. The polymerizable composition contains a liquid-crystalline polymerizable liquid crystal compound having a low birefringence, and can yield a highly-durable optical film.
