MICROCAPSULE PROVIDED WITH HEAT RESISTANCE AND ITS PRODUCTION

摘要

PURPOSE:To produce microcapsules capable of fulfilling the objective function without deteriorating the included core substance and the wall material even when used after heat treatment at a high temp. such as melt kneading in resin or baking finish. CONSTITUTION:Heat resistant fine particles are dispersed in the continuous liq. phase of a dispersion liq. contg. microcapsules including a core substance and the liq. phase is dried to coat the surfaces of the walls of the microcapsules with the fine particles. The objective heat resistant microcapsules are produced.
