Abstract

Process for forming low porosity microcapsule films, characterized in that a water soluble or dispersible heterocyclic amine is chemically or ionically bonded with a microcapsule film forming material or by depositing said heterocyclic amine alone or a material insoluble in water formed by reaction with said amine on the film of microcapsules.
