摘要: This microcapsules are mono-core type microcapsules with particle size from 5 .mu.m to 5 mm on which waxes are coated as the 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 a use of lesser amount of waxes.
