Abstract
L'INVENTION CONCERNE L'INDUSTRIE CHIMIQUE ET CELLE DE L'ENREGISTREMENT MAGNETIQUE. UN MILIEU D'ENREGISTREMENT MAGNETIQUE AYANT UNE COUCHE AIMANTABLE EST CONSTITUE DE PARTICULES AIMANTABLES DANS UN LIANT FAIT D'UN LATEX AQUEUX CONSTITUE DE FACON TYPIQUE D'UN COPOLYMERE DE 100PARTIES D'ACRYLATE D'ALKYLE INFERIEUR, DE 14 PARTIES D'ACIDEMETHACRYLIQUE ET DE 9PARTIES DE METHACRYLATE DE GLYCIDYLE; LE LIANT EST AUTORETICULABLE, CE QUI PERMET D'OBTENIR UNE EXCELLENTE RESISTANCE A L'ADHERENCE DE CONTACT MUTUEL ET A L'USURE; LA NATURE AQUEUSE DU LATEX DU LIANT SUPPRIME LES DANGERS DE POLLUTION ET D'INCENDIE. APPLICATION NOTAMMENT AUX BANDES D'ENREGISTREMENT MAGNETIQUE SONORE ET VIDEO.
