Abstract:
A coating photoreactive composition comprising a hydrolyzed epoxy-silane and other active ingredients is able to provide an organic dye-tintable abrasion resistant coating without the use of traditional dye-tinting enhancing agents such as polymerizable ethers or polymerizable diethers. The compositions exhibit consistently higher abrasion resistance without significant impact on tintability.
