Title:
RESIN COMPOSITION FOR WATER-REPELLENT LENS PROTECTION FILM AND METHOD FOR PROTECTING WATER-REPELLENT LENS
Document Type and Number:
Japanese Patent JP2022057609
Kind Code:
A
Abstract:
To provide a resin composition for a water-repellent lens protection film that has controlled coating property and adhesion to a lens subjected to super water-repellency which can be uniformly coated to a lens having high water repellency and can be cured even with an LED light source having a peak wavelength of 395 nm.SOLUTION: A resin composition for a water-repellent lens protection film contains (A) polyfunctional (meth)acrylate having a weight average molecular weight of 200-30,000, (B) a photopolymerization initiator, and (C) a nonionic surface active agent. The resin composition for the water-repellent lens protection film can be uniformly coated to even the whole of a water-repellent lens that has water-repellency and is difficult to be coated to the surface, and a protective film formed of the resin composition for the water-repellent protection film prevents axis deviation at the time of lens circumference processing, and can be easily peeled without a residue in peeling.SELECTED DRAWING: Figure 1
