Abstract
Articles are disclosed wherein a color-imparting non-hiding coating layer is deposited on a surface thereof. The coating layer is deposited from a protective coating composition comprising color-imparting particles having a maximum haze of about 10% and a film-forming resin. Methods of using the coatings, and the substrates coated therewith, are also disclosed.
Claims31
A multi-layer coating comprising:
- (a) a color-imparting, non-hiding coating layer deposited from a protective coating composition comprising an aqueous dispersion comprising color-imparting particles stably dispersed in aqueous medium in admixture with one or more polymers, and
- (b) a clear coat layer deposited over at least a portion of the color-imparting, non-hiding layer.
A method of forming and aqueous dispersion of color imparting particles comprising:
- (a) admixing the color-imparting particles with
- (1) one or more polymerizable ethylenically unsaturated monomers, or
- (2) a mixture of one or more polymerizable, ethylenically unsaturated monomers with one or more polymers, or
- (3) one or more polymers to form an admixture;
- (b) subjecting the admixture to high stress, shear conditions to particularize the admixture into microparticles;
- and
- (e) polymerizing the ethylenically unsaturated monomers when present
- (f) dispersing the particles in aqueous medium.
