Abstract
A coating composition having excellent antifogging property, good abrasion resistance, improved adhesion to the substrate and good water resistance, which comprises an epoxy functional organosilane or the hydrolysate or condensate thereof; an amino functional organosilane or the hydrolysate or condensate thereof; a hydrophilic (meth)acrylate monomer, or a copolymer of two components selected from the hydrophilic (meth)acrylate monomer, another hydrophilic monomer and an organosilane and/or a terpolymer of the three components; a curing catalyst; and, optionally, a multi-functional (meth)acrylate monomer having at least two (meth)acryl groups and a radical polymerization initiator.
