Abstract:
1. A method of forming a transparent coating on a substrate, the transparent coating having a color effect, resistance to UV light-induced degradation and/or scratch resistance, comprising: applying a curable clear coat composition comprising a first nanoparticle precursor, wherein the curable clear coat composition comprising a first nanoparticle precursor is substantially free of undissolved first nanoparticle precursor; and curing the curable clear coat composition to form a transparent coating comprising a polymer selected from the group consisting of: aminoplasts, melamine formaldehydes, carbamates, polyurethanes, polyacrylates, epoxies, polycarbonates, alkyds, vinyls, polyamides, polyolefins, phenolic resins, polyesters, polysiloxanes; and combinations of any of these; and a plurality of in-situ formed nanoparticles having an average particle size in the range of about 1-100 nanometers, inclusive, wherein the plurality of nanoparticles confers a color effect, resistance to UV light-induced degradation and/or scratch resistance to the transparent coating.
