METHOD FOR SEPARATION OF MICROCAPSULES AND PREPARATION OF PRINTING INKS

摘要

A method for forming microcapsules which comprises the steps of: preparing a slurry of microcapsules containing an ionic or polar emulsifier; adding a de-emulsifier to said slurry under such conditions that said de-emulsifier coulombically interacts with said emulsifier and said slurry separates into an aqueous phase and a microcapsule rich phase; and separating said microcapsules from said slurry.
