Title:
PHOTOCURABLE COMPOSITION CONTAINING FLUORINE POLYMER
Document Type and Number:
WIPO Patent Application WO/2018/212263
Kind Code:
A1
Abstract:
Provided is a photocurable composition which has excellent transparency and wear resistance, and which is useful as a protective coating agent for optical members such as eye glasses and sunglasses, or for displays of portable electronic devices. A photocurable composition which contains (A) a fluorine polymer, (B) a urethane (meth)acrylate and (C) a photopolymerization initiator, and wherein: the fluorine polymer (A) contains a constituent unit A-1 that is derived from a fluorosilsesquioxane having one addition polymerizable functional group in each molecule and a constituent unit A-2 that is derived from an addition polymerizable monomer and has a group having a polymerizable unsaturated bond in a side chain; and the constituent unit A-1 is derived from a fluorosilsesquioxane represented by formula (1). (In the formula, each of Rf 1-Rf 7 independently represents a fluoroalkyl group having 1-20 carbon atoms, wherein an arbitrary methylene group may be substituted by an oxygen atom, a fluoroaryl group having 6-20 carbon atoms, wherein at least one hydrogen atom is substituted by a fluorine atom or a trifluoromethyl group, or a fluoroarylalkyl group having 7-20 carbon atoms, wherein at least one hydrogen atom in the aryl group is substituted by a fluorine atom or a trifluoromethyl group; and A1 represents an addition polymerizable functional group.)
