A sprayable, solvent-borne, primer composition for use as a first coat on li ght-sensitive, automotive plastic parts. The primer serves as a barrier to block ultraviole t light penetration to the underlying substrate and to prevent migration of substrat e degradation and by-products up into the topcoat finishes. The primer is a solvent blend of a film-forming crosslinkable polymer resin, a crosslinker for the resin, a catalyst, carbon black pigments surface modified with a polymer dispersant and an organic pigment derivative co-dispersant, crosslinked polymer microgel particles, and U.V. absorbers and optional anti oxidants. The surface modification on the carbon black pigments results in higher pigment loadings, which, in turn, imparts U.V. light protection at exceptionally low dry film builds. Furthermore, the microgel particles cause the primer to build in viscosity and set up a gel s tructure in its uncured state, which allows the primer to be overcoated wet-on-wet with auto motive ...
