Abstract
Microcapsules having controlled structural integrity are produced by a process which involves admixing a thermosetting condensation polymer-containing oily solution and a polymer-containing aqueous solution and causing a chemical reaction between the polymers at the resulting oil/water interface. The so-formed microcapsules have excellent water resistance and may be employed in the formation of opacifying agents in coatings and particularly in paint films.
