Anti-fogging compositions and anti-fogging products

Abstract

This invention provides an antifogging composition comprising a copolymer (A), colloidal silica (B), and a glycidyl-containing compound (C). The copolymer (A) is a (meth)acrylate copolymer obtained from a monomer mixture comprising at least one monomer (a-1) represented by general formula (1), and the glycidyl-containing compound (C) is a glycidyl-containing compound represented by general formula (2). This antifogging composition can form an antifogging coating with excellent transparency, initial antifogging properties, initial adhesion, and resistance to water stains. Even when a low-temperature cured coating is exposed to high temperature and humidity for an extended period, its adhesion will not decrease.
