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.
L'invention décrit des compositions aqueuses d'une quantité efficace d'au moins un matériau photosensible et d'au moins un composant polymérisable qui sont adaptées pour former au moins partiellement des microparticules photosensibles ou au moins des microparticules polymères photosensibles réticulées. Les microparticules polymères photosensibles sont constituées d'une surface structurelle et de domaines internes ; au moins une des surfaces et/ou un des domaines internes sont photosensibles. L~invention décrit également des dispersions aqueuses de ces microparticules, des façons de produire de telles microparticules et des articles photosensibles tels que des éléments optiques qui incluent les microparticules polymères photosensibles.
