Various methods for producing non-aqueous dispersions of photosensitive polymer particulates are described, wherein (a) preparing one or more aqueous dispersions of polymerizable components, at least one of which is photosensitive. Containing a substance, the polymerizable component comprising at least one hydrophilic functional group and / or at least one hydrophobic functional group; and (b) the dispersion of (a) to form microparticles Subjecting to sufficient conditions; (c) at least partially polymerizing the polymerizable component; (d) combining the dispersion with an organic continuous phase comprising an organic solvent; and (e) a non-aqueous dispersion. Removing the water from the dispersion so that the final water content of is less than 30 percent by weight, the step performed before or after (d); and (f) any acid functionality on the surface of the microparticles Group, anti And a step of reacting with sexual material. |
