摘要： A process for preparing silicate shell microcapsules comprises adding a water reactive silicon compound to an oil in water emulsion, thereby condensing and polymerizing the water reactive silicon compound to form silicate shell microcapsules having a core comprising the oil phase of the said emulsion. The water reactive silicon compound comprises a tetraalkoxysilane and an alkoxysilane having an amino or quaternary ammonium substituted alkyl group.
