Abstract
PURPOSE:To improve the dispersibility of magnetic powder and to improve wear resistance and durability by introducing acidic groups, epoxy group and hydroxyl group into the binder resin of a magnetic layer. CONSTITUTION:This disk-shaped magnetic recording medium is formed by kneading and dispersing ferromagnetic material particles together with a binder resin soln. and coating the dispersion thereof on a nonmagnetic material. A vinyl chloride resin having at least one kind of the acidic groups or the acid groups forming the salts thereof as well as the epoxy group and hydroxyl group is incorporated into the binder resin of said magnetic layer. Ester which consists of alcohol of >=6C having a branch and fatty acid of >=12C and ester which is solid at ordinary temp. are further incorporated into this magnetic layer. The dispersibility of the fine particle magnetic powder is thereby improved and the disk-shaped magnetic recording medium having the good wear resistance, surface lubricity or durability is thereby obtd.
