Abstract

La présente invention est relative à la formation d'image par électrophorèse. Le procédé suivant l'invention consiste à soumettre des particules 4, contenant au moins de la trans-épindolidione comme colorant jaune, à un champ électrique appliquée entre deux électrodes 1 et 5, et à exposer ces particules à un rayonnement de manière à former une image de colorant sur au moins l'une de ces électrodes. Application à l'obtention d'images par électro-phorèse présentant une excellente tonalité jaune.
