Abstract

PURPOSE:To form dense walls which are insoluble in water by dispersing a specific isocyanate compound into a polyvinylalcohol polymer soln. having a clouding point and elevating the temp. of the system to above the clouding point then hardening the same. CONSTITUTION:In the case of an aqueous soln., a polyvinylalcohol (PVA) polymer having a clouding point is used, and an isocyanate compound having two or more isocyanate groups in molecules is dispersed into this aqueous soln. Thence, the temp. of the entire part of the system is elevated to above the clouding point of tue aqueous PVA polymer soln. to deposit the concd. aqueous soln. of the PVA polymer around the core material as a dispersed phase, thereafter the capsule walls are cured by a compound having high crosslinking reactivity to PVA polymers. There are tolylene diisocyanate, hexamethylene diisocyanate, etc. as the isocyanate compound which is the capsule core material.
