Abstract:
Described are non-aqueous dispersions of photosensitive polymeric microparticles, comprising: a) an organic continuous phase comprising an organic solvent; and b) photosensitive polymeric microparticles dispersed in the organic continuous phase. The microparticles comprise an at least partially polymerized component having integral surface and interior domains, wherein the surface domain comprises a polymeric material that is solubilized by the organic solvent, the interior domain comprises a polymeric material that is insoluble in the organic solvent, and the surface domain and/or interior domain is photosensitive. Also described are methods of producing such non-aqueous dispersions, curable film-forming compositions containing them, and photosensitive coated substrates.
