| titleOfInvention | PROCEDURE TO PREPARE MICROCAPSULES BY COACERVATION. |
| abstract | A process for preparing microcapsules by coacervation using a solution containing at least two hydrophilic colloids having opposite electric charges at least one of said colloids being gellable, comprising emulsifying or dispersing a hydrophobic oil or dust in said solution, causing coacervation of said colloids to form a coacervate wall, gelling said coacervate wall, and hardening said coacervate wall, the improvement which comprises on hardening the coacervate wall, at a temperature not higher than the gel point of said gellable colloid, adding an aqueous solution of (1) a high molecular weight electrolyte having an anionic function group and (2) a condensate represented by the following general formula WHEREIN R1 and R2 each represent a hydrogen atom or an alkyl group having from 1 to about 18 carbon atoms so long as at least one of R1 and R2 is an alkyl group, X represents a hydrogen atom or an alkali metal atom and n is a positive integer, is disclosed. |
