ADHESIVES INCLUDING MCIRO CAPSULE

摘要

Microcapsule-contg. adhesive(I) of chemical reaction or solvent- activated hardening type is prepd. Thus, very fine liq. particles of at least one component of the (I) is dispersed in aq. soln. of aminoplast components and acid catalyst is added so that aminoplast prepolymers undergoes polycondensation. A modifying agent(II) is added to aq. dispersion during polymerization so that microcapsules are formed which enclose at least one component of (I) within the membrance consisting substantially of the (II)-modified aminoplast. The microcapsules are collected, dried, and dispersed in other components which form the (I) with microcapsules.
