Abstract
Described are aqueous compositions of an effective amount of at least one photosensitive material and at least one polymerizable component that are adapted to at least partially form photosensitive microparticles or at least partially crosslinked photosensitive polymeric microparticles. The photosensitive polymeric microparticles are made of integral surface and interior domains wherein at least one of the surface and/or interior domains is photosensitive. Also described are aqueous dispersions of such microparticles, ways of producing such microparticles and photosensitive articles such as optical elements that incorporate the photosensitive polymeric microparticles.
