CURABLE COMPOSITION FOR FLEXIBLE HARD COAT

WIPO Patent Application WO/2020/162326

A1

[Problem] To provide a curable composition capable of forming a hard coat layer having extremely high scratch resistance, hardness, stretchability, bendability, and stain resistance. [Solution] Disclosed are: a curable composition comprising (a) 100 parts by mass of an active energy ray-curable non-oxyethylene-modified polyfunctional monomer, (b) 30 parts by mass to 150 parts by mass of an active energy ray-curable oxyethylene-modified polyglycerin polyfunctional monomer, (c) 0.05 parts by mass to 10 parts by mass, per 100 parts by mass in total of the component (a) and the component (b), of a perfluoropolyether including a poly(oxyperfluoroalkylene) group and having, on both terminals of the molecular chain thereof, an active energy ray-polymerizable group with an urethane bond interposed therebetween (excluding perfluoropolyethers having a poly(oxyalkylene) group between the poly(oxyperfluoroalkylene) group and the urethane bond), and (d) 1 part by mass to 20 parts by mass, per 100 parts by mass in total of the component (a) and the component (b), of a polymerization initiator that generates radicals by active energy rays; and a hard coat film including a hard coat layer formed by the composition.
