Title:
CURABLE COMPOSITION FOR HARD COAT
Document Type and Number:
WIPO Patent Application WO/2022/034733
Kind Code:
A1
Abstract:
[Problem] To provide a material for forming a hard coat layer that has both excellent sliding properties and excellent durability characteristics such as abrasion resistance and wear resistance, which are usually in a trade-off relationship. [Solution] A curable composition which contains (a) an active energy ray-curable polyfunctional monomer, (b) a perfluoropolyether which has an active energy ray-polymerizable group at an end of a molecular chain containing a poly(oxyperfluoroalkylene) group (excluding a perfluoropolyether (c) described below), (c) a perfluoropolyether which has a molecular weight of 1,000 or more, while having a group represented by formula (1), formula (2) or formula (3) at an end of a molecular chain containing a poly(oxyperfluoroalkylene) group, and (d) a polymerization initiator which generates radicals by means of an active energy ray. (In the formulae, R1 represents a trifluoromethyl group, a fluoro group, a trifluoromethoxy group or a nitro group; in cases where R1 represents a trifluoromethyl group, a trifluoromethoxy group or a nitro group, m represents an integer from 1 to 5; in cases where R1 represents a fluoro group, m represents an integer from 2 to 5; R2 represents a methyl group or a methoxy group; n represents 1, 2 or 3; R3 represents an alkyl group having from 3 to 10 carbon atoms; and * represents a bonding hand bonded to a molecular chain containing a poly(oxyperfluoroalkylene) group of the perfluoropolyether (c).)
