Abstract
Radiator-Curable coating compositions which form transparent, abrasion-resistant, tintable coatings upon curing by exposure to high intensity irradiation, such as ultraviolet light or electron beam irradiation. The coating composition comprises a combination of effective amounts of (a) colloidal silica, (b) the hydrolysis product of a silane compound having a polymerizable functional group such as acryloxy-functional silanes or glycidoxy-functional silanes or mixtures of both, (c) polyfunctional, polymerizable, non-acrylate-functional ethers, (d) at least one radiation sensitive initiator and, preferably, (e) a monofunctional monomer. When the surface of a substrate coated with the cured coating composition is immersed in a colored dye bath for a sufficient period of time, the coating absorbs or transmits to the substrate a desired amount of dye.
