Abstract
L'invention concerne la préparation de micro-capsules contenant une huile. Elle se rapporte à un procédé qui comprend la formation d'une solution aqueuse contenant deux matières colloïdales hydrophiles ayant des charges électriques opposées et des gouttelettes d'huile dispersées, puis la coacervation du systèmes aqueux à une température relativement élevée et le refroidissement de la suspension de coacervat, en présence d'une agitation correspondant à des conditions bien particulières. Application à la préparation de papier de copie sensible à la pression.
