Abstract:
A curable, powder-based coating composition for coating a substrate, having a first color effect, with a film layer wherein application of the film layer to the substrate produces a second color effect different from the first color effect of the substrate, said powder-based coating composition comprising:(A) a powder-based binder comprising the reaction product of; (I) a resin having a functional group, and (II) a cross-linking agent reactive with said functional group of said resin; and (B) pigment consisting essentially of a color effect-providing pigment comprising; (I) a pigment substrate having first and second substantially parallel and planar surfaces, and (II) an inorganic coating disposed on at least one of said first and second substantially parallel and planar surfaces of said pigment substrate (B)(I), said inorganic coating (B)(II) having an index of refraction of 1.8 or less; wherein said inorganic coating (B)(II) and said pigment substrate (B)(I) of said color effect-providing pigment (B) interact with the first color effect of the substrate to produce the second color effect upon application of the film layer of the powder-based coating composition to the substrate.
