ABSTRACT:
Pressure-rupturable, oil-containing microcapsules are produced by admixing a water-immiscible, oily material containing an oil-soluble, cross-linking agent, which is either a polyfunctional isocyanate or an orthoester of a group IV element with an aqueous solution of an emulsifying agent comprising starch having ether-linked aralkyl groups, to cross-link the emulsifier and form a capsule wall at the oil/water interface of the resulting oil-in-water emulsion around the oil droplets. The emulsifying agent is the sole co-reactant for the oil-soluble cross-linking agent.
