Abstract

POUDRE D'AGENT DE VIRAGE POUR LE DEVELOPPEMENT D'IMAGES ELECTROSTATIQUES. LA POUDRE EST COMPOSEE PAR DES PARTICULES COMPRENANT UNE RESINE THERMOPLASTIQUE ISOLANTE, UNE MATIERE COLORANTE ET, SI DESIRE, UN AGENT DE COMMANDE DE POLARITE A ACTION NEGATIVE. UNE PARTIE PRINCIPALE DE LA RESINE THERMOPLASTIQUE ISOLANTE EST CONSTITUEE PAR UNE RESINE EPOXYDE MODIFIEE AYANT UNE MASSE MOLAIRE DE L'EPOXYDE D'AU MOINS 8000, UNE VISCOSITE A L'ETAT FONDU, A 140C, COMPRISE ENTRE 2 ET 200000S.PA ET UNE TEMPERATURE DE TRANSITION VITREUSE COMPRISE ENTRE 45 ET 80C, PREPAREE A PARTIR D'UNE RESINE EPOXYDE AYANT UNE MASSE MOLAIRE D'EPOXYDE NETTEMENT PLUS FAIBLE, PAR BLOCAGE D'AU MOINS 5 DE SES GROUPES EPOXY AVEC UN ACIDE CARBOXYLIQUE, UN PHENOL OU UN DI-ARYL-SULFONAMIDE MONOFONCTIONNEL ET, FACULTATIVEMENT, JUSQU'A 95 DE SES GROUPES EPOXY BLOQUES SOIT PAR REACTION INTERMOLECULAIRE AVEC LES GROUPES ALCOOLIQUES DE LA RESINE EPOXYDE SOIT PAR REACTION AVEC UN DURCISSEUR D'EPOXYDE. APPLICATION, EN PARTICULIER, AUX REVELATEURS NEGATIFS.
