ABSTRACT:
Described are optical elements made of a substrate and a curable film-forming composition applied to at least a portion of the substrate to form a coating thereon. The curable film-forming composition comprises:i) a resinous material comprising a monomer, oligomer, and/or polymer containing reactive functional groups;ii) a curing agent having two or more reactive functional groups that are reactive with functional groups in the resinous material of i); andiii) a material different from i) and ii), comprising a blocked isocyanate group blocked with a blocking agent capable of deblocking at a low temperature. The material of iii) is present in the curable film-forming composition at least in an amount sufficient to improve adhesion between the curable film-forming composition and the substrate and/or a superposed coating compared to a substantially identical optical element that does not comprise the material of iii) in the curable film-forming composition.
