Title:
CURABLE COMPOSITION FOR FLEXIBLE COATING
Document Type and Number:
WIPO Patent Application WO/2020/008937
Kind Code:
A1
Abstract:
[Problem] To provide a curable composition, with which it is possible to form a hard coat layer that is extremely scratch-resistant and stretchable and furthermore can also be wear-resistant. [Solution] Provided are: a curable composition including (a) 100 parts by mass of an oxyethylene-modified polyfunctional monomer that has at least three active energy beam-polymerisable groups, the average oxyethylene modification amount of said monomer being less than 3 mol in relation to 1 mol of said polymerisable groups, (b) 0.1-10 parts by mass of a perfluoropolyether that has an active energy beam-polymerisable group at both ends of the molecular chain, which includes a poly(oxyperfluoroalkylene) group, with a urethane bond therebetween (excluding a perfluoropolyether having a poly(oxyalkylene) group between the poly(oxyperfluoroalkylene) group and the urethane bond), and (c) 1-20 parts by mass of a polymerisation initiator that produces radicals by means of an active energy beam; and a hard coat film comprising a hard coat layer formed by said composition.
