CURABLE COMPOSITION FOR FLEXIBLE HARD COATING

WIPO Patent Application WO/2020/162323

A1

[Problem] To provide a material for forming a hard coat layer having excellent abrasion-resistance and stretchability. [Solution] The present invention pertains to: a curable composition containing (a) 100 parts by mass of an active energy ray-curable polyfunctional monomer selected from the group consisting of (a-1) active energy ray-curable oxyethylene modified polyfunctional monomers and (a-2) active energy ray-curable lactone modified polyfunctional monomers, (b) 0.05-10 parts by mass of a perfluoropolyether including a poly(oxy perfluoro alkylene) group, (c) 10-65 parts by mass of silica particles having respective surfaces thereof modified with a silane coupling agent including a nitrogen-containing proton-donating functional group, and (d) 1-20 parts by mass of a polymerization initiator that generates radicals by active energy rays; and a hard coat film provided with a hard coat layer formed by said curable composition.
