Abstract

L'invention concerne la préparation de microcapsules contenant une huile. Elle concerne un procédé qui consiste à former une solution aqueuse d'au moins deux matières colloïdales hydrophiles ayant des charges électriques opposées. Des gouttelettes d'huile sont dispersées dans cette solution. Ces gouttelettes contiennent au moins un isocyanate polyvalent Le procédé consiste à provoquer ensuite une coacervation du système aqueux, à une température relativement élevée, et à refroidir la suspension de coacervat, sous agitation, dans des conditions particulières. Domaine application : préparation de papier autocopiant, de papier de copie sensible à la pression, etc.
