MONO-CORE TYPE MICROCAPSULES AND PROCESS FOR PRODUCING THEM

摘要

Mono-core type microcapsules comprising core particles with a particle size from 5 mu m to 5 mm on which waxes are coated as a layer on the surface of the particles and/or penetrated to the inside of the particles, in which said wax coating is prepared by once melting the wax particles over the surface of the core particles and then re-solidifying them. …The core material of the microcapsule undergoes less thermal degradation and can be formed with a dense and thin membrane profiling the surface layer thereof with the use of lesser amount of waxes.
