Abstract

L'invention est relative à une bande magnétique d'enregistrement et à son procédé de fabrication. Une couche intermédiaire formée par une résine époxydique à polymérisation cationique pour la couche aimantable d'une bande magnétique d'enregistrement à support formé par un ruban de polyester agit comme barrière contre l'extraction et la migration des composants de bas poids moléculaire du ruban de support en polyester, composants qui sinon auraient tendance à se cristalliser sur la surface de la couche aimantable. Ces bandes évitent l'accumulation de composants provenant de leur ruban de support sur les têtes d'enregistrement et de reproduction.
