Described are various methods of producing non-aqueous dispersions of photosensitive polymeric microparticles, comprising: (a) preparing one or more aqueous dispersions of a polymerizable component, at least one of which contains a photosensitive material and, wherein 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 microparticles; (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; wherein e) is performed before or after d); and (f) reacting any acid functional groups on the surface of the microparticles with a reactive material having at least one epoxy functional group, at least one thiocarbonylthio functional group, at least one alkoxyamine functional group, or at least one halide functional group.
