Document Type and Number:
WIPO Patent Application WO/2022/071446
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a resin composition for water-repellent lens protective films, that can be uniformly applied in particular even in the case of an ultra-water-repellent lens having a high antifouling performance. In order to solve the problem, a resin composition for water-repellent lens protective films is provided that comprises (A) a polyfunctional (meth)acrylate having a weight-average molecular weight of 200-30,000, (C) a photopolymerization initiator, and (D) a nonionic surfactant. The present invention can thereby provide a resin composition for water-repellent lens protective films, that can be uniformly applied in particular even in the case of an ultra-water-repellent lens having a high antifouling performance.
