Abstract

Procedimiento de obtención de microcapsulas para sistemas de copia, caracterizado porque comprende las etapas de dispersar una sustancia hidrofoba, que funde a una temperatura de 40 a 150 º C, en una solución acuosa de un polímero, hasta que la sustancia líquida hidrofoba tenga un tamñalo de particula de 5 a 50 micras de diámetro; y, a continuación, encapsular las gotitas de la sustancia hidrofoba, añadiendo productos de condensación de melamina-formaldehido solubles en agua, parcialmente metilado , a un pH de 4,5 a 5.
