Abstract

Elément d'enregistrement magnétique comprenant un support et un recouvrement contenant des particules magnétisables finement dispersées dans un liant à l'aide d'un dispersant. Le dispersant est constitué par le sel d'une amine et d'acide phosphorique qui est mono-estérifié ou di-estérifié à l'aide d'un alcool oléfinique supérieur comptant 12 à 22 atomes de carbone et pouvant être alcoxylé. A titre d'exemple un dispersant utile, on mentionne le sel d'oléylamine d'acide phosphorique estérifié à l'aide d'alcool oléylique éthoxylé comptant 5 à 18 groupes éthoxy. Les dispersants sont de nouveaux produits. Application : enregistrement magnétique.
