Document Type and Number:
WIPO Patent Application WO/2021/241087
Kind Code:
A1
Abstract:
[Problem] To provide a material for forming a hard coat layer that has both excellent abrasion resistance and excellent stretchability, which are usually in a trade-off relationship. [Solution] A curable composition according to the present invention, which contains (a) 100 parts by mass of a urethane (meth)acrylate, (b) from 5 parts by mass to 70 parts by mass of silica particles which are surface-modified with a silane coupling agent that has at least one nitrogen-containing proton-donating group selected from the group consisting of an amino group, an amide group, a urea group, a thiourea group, a thiourethane group, a ureido group and a thioureido group, (c) from 0.05 part by mass to 10 parts by mass of a perfluoropolyether which has an active energy ray-polymerizable group at an end of a molecular chain that contains a poly(oxyperfluoroalkylene) group, and (d) from 1 part by mass to 20 parts by mass of a polymerization initiator which generates radicals by means of an active energy ray.
