LYOPHILIZED HOLLOW PARTICLE AND ITS MANUFACTURING METHOD, AND COMPOSITION CONTAINING HOLLOW PARTICLE AND TREATED ARTICLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To prevent scattering of hollow particles easy to scatter because of its light weight and hard to handle, and to provide lyophilized hollow particles having no problems on the manufacture and management at a factory in treating and processing and in danger of fire on storage for the treated articles caused by using a conventional flammable organic solvent, and no economical problems, and neither blocking during preservation nor contamination of containers caused by wetting by an organic solvent in operation sites. SOLUTION: The lyophilized hollow particulates are obtained by coating the surface of hollow particulates with a lyophilic hot melt organic substance solid at ordinary temperature. There are also provided a manufacturing method of the hollow particulates, a composition containing the hollow particulates, an article obtained using the same and an article treated with the same.
