Abstract
Transparent resin composites comprising a substrate of a transparent plastic material coated with a cured film of at least one [(2,3-epoxypropoxy)alkyl]trialkoxysilane or of at least one [(2,3-epoxypropoxy)alkyl]trialkoxysilane and at least one transparent polymer compatible with said silane are provided. The resin composites have excellent abrasion resistance, surface hardness, heat resistance, chemical resistance, weathering resistance, etc. well retaining the transparency and other optical characteristics of the substrate resin. These resin composites can be used as transparent plastic panels, lenses, etc.
