Abstract
Abstract A thermosetting resin composition comprising (A) the hydrolysate of an alkoxysilane represented by either of the general formulas: ##STR1## wherein R 1 and R 2 are respectively a divalent group, R 3 is a lower alkyl and R 4 is R 3 or OR 3 and (B) a polymer or copolymer of monomers represented by the general formula ##STR2## wherein R is a hydroxyalkyl and X is hydrogen or methyl is provided. This composition forms a transparent anti-fogging abrasion-resistant coating on the surface of glass, metals and synthetic resins.
