ABSTRACT:
The polymerization and copolymerization of photographically useful vinyl monomers can be effected by dissolving such monomers in an isotropic oil-in-water microemulsion or in an isotropic water-in-oil microemulsion, each comprising monomers or comonomers, surfactants and/or cosurfactants, water, and optionally electrolytes. The microemulsion may be characterized as transparent or nearly transparent to the eye at 1% (w/w) or greater monomer, ultrafine in particle (droplet) size (typically in the range of 30 to 900 .ANG. in diameter), and spontaneously formed upon combining all the components with moderate stirring. The polymerization process is subsequently initiated with free radical initiators or with ultraviolet light. The components are chosen so that photographically useful polymers or photographically useful latexes are obtained, and said polymers or latexes may be coated in a photographic element.
