Abstract

L'invention concerne un procédé de préparation de microcapsules. Une solution de capsules est préparée en polymérisant de l'urée et du formaldéhyde en présence de gomme arabique pour former une paroi en résine urée-formaldéhyde autour d'une solution huileuse hydrophobe. L'utilisation de la gomme arabique réduit la viscosité de la solution. Application notamment aux papiers copiants sensibles à la pression.
