Abstract

PURPOSE:To prepare microcapsules excellent in mechamical strength without impairing the physiological and chemical activity of a core material, by introducing a photosensitive hydrophobic group into a hydrophilic high molecular cpd. used as a capsule-forming polymer in order to photo-crosslink without using a crosslinking agent. CONSTITUTION:A photo-crosslinkable high molecular cpd. made by introducing a hydrophobic photosensitive group 9 (e.g., cinnamoyl group) into a hydrophilic high molecular base material such as PVA etc. is dissolved in a nonaqueous org. solvent (e.g., CHCl3). The conc. of the high molecular cpd. lies in the range 0.1- 3 wt.%, pref., 0.15-1.5 wt.%. To the soln. of the high molecular cpd. is added core material which is to be coated with capsules (e.g., pharmaceuticals, agricultural chemicals, chemicals), then the soln. is added to water or aq. soln. of emulsifying agent, and is stirred violently in order to emulsity it. The emulsion is irradiated with light in order to crosslink the high molecular cpd. through the photosensitive group so as to produce core-material-enveloping microcapsule which has been formed from high molecular cpd. with photocrosslinked shell.
