METHODS FOR PRODUCING PHOTOSENSITIVE POLYMERIC MICROPARTICLES

摘要

PROBLEM TO BE SOLVED: To provide a method for producing non-aqueous dispersion of photosensitive polymeric micro-particles.SOLUTION: Described are various methods of producing non-aqueous dispersion of photosensitive polymeric micro-particles, comprising the steps of: (a) preparing one or more aqueous dispersion of a polymerizable component, at least one of which contains a photosensitive material and, where the polymerizable components comprise at least one hydrophilic functional group and/or at least one hydrophobic functional group; (b) subjecting the dispersion of (a) to conditions sufficient to form micro-particles; (c) at least partially polymerizing the polymerizable component; (d) combining the dispersion with an organic continuous phase comprising an organic solvent; (e) removing water from the dispersion such that the final water content of the non-aqueous dispersion is less than 30 percent by weight; where e) is performed before or after d); and (f) reacting any acid functional groups on the surface of the micro-particles with a reactive material.
