Title:
CURABLE COMPOSITION FOR HARD COAT
Document Type and Number:
WIPO Patent Application WO/2022/190937
Kind Code:
A1
Abstract:
[Problem] To provide a homogeneous curable composition that is free of suspended matter and sediment, and is capable of forming a hard coat layer provided with high-standard characteristics, both in durability and in smoothness, as well as high liquid repellency when actual use thereof is assumed. [Solution] Provided is a curable composition that includes: (a) 100 parts by mass of an active energy ray-curable polyfunctional monomer having two or more (meth)acryloyl groups per molecule; (b) 0.05 -2 parts by mass of perfluoropolyether having, via a poly(oxyalkylene) group, an active energy ray-polymerizable group only in one end of a molecular chain which includes a poly(oxyperfluoroalkylene) group, and having a weight average molecular weight of 1500-3500; and (c) 1-20 parts by mass of a polymerization initiator which generates radicals due to active energy rays.
