Abstract
Paint compositions and coatings having improved overall visual appearance, richness or depth of color and aesthetic properties such as for spraying-painting automobiles, boats, aircraft and home appliances. The present paint compositions are high solids content, heat-curable, transparent or translucent compositions containing embedded light-refractive colorless and/or tinted transparent glass beads preferably between about 10 to 20 microns diameter, and one or more color-enhancing agents such as pigments, dyes, aluminum flakes, mica, opaque glass beads, holographic flakes, and similar conventional light-enhancing agents. The present bead-containing refractive paint compositions may be based upon volatile organic solvents, water or may be solvent-free powder compositions, but in all cases the resinous binder material is cross-linkable at the baking temperature of the paint, or upon exposure to ultraviolet radiation, to cure as a hard, translucent, chip-resistant paint.
