Title: Thermosetting resin composition comprising an [(2,3-epoxypropoxy)alkyl]trialkyloxysilane

Abstract: A novel thermosetting resin composition comprising at least one [(2,3-epoxypropoxy)alkyl]trialkoxysilane and at least one selected from polymers, prepolymers, copolymers and coprepolymers of epoxy-group-containing vinyl monomers, which may further contain at least one selected from polymers, prepolymers, copolymers and coprepolymers of vinyl monomers containing no epoxy group, is disclosed. This composition is cured by heating with addition of a ring-opening polymerization catalyst and remarkably improves surface hardness, abrasion resistance, weathering resistance, chemical resistances, heat resistances, etc. of acrylic resins and many other plastic materials without imparing the inherent transparency and other optical properties of these materials when it is applied on the surface of them and cured.
