Zusammenfassung:	PURPOSE:To improve crosslinking property, to avoid problem such as cohesion, and to improve traveling property and durability by using a vinyl chloride resin having primary hydroxyl group with alkylene oxide chain on a side chain as a binder. CONSTITUTION:The magnetic recording medium consists of a nonmagnetic supporting body and a magnetic layer essentially comprising magnetic powder and a binder thereon. The binder contains such a vinyl chloride resin expressed by formula 1. In this formula, l, m, n are wt.% of each unit satisfying l+m+n=11, 4
