Magnetic recording medium

A magnetic recording medium comprising a nonmagnetic support and a magnetic recording layer provided on the support, said magnetic recording layer comprising a binder and a ferromagnetic powder dispersed therein, which is characterized in that said binder is composed of a resin component comprising:

• a vinyl chloride copolymer containing a repeating unit having at least one polar group selected from the group consisting of --SO.sub.3 M, --OSO.sub.3 M, and --PO(OM').sub.2, wherein M is hydrogen or an alkali metal atom, and M' is hydrogen, an alkali metal atom or a lower hydrocarbon group, and a repeating unit having a epoxy group in an amount of from 1 to 30 mol%;
• and
• a polyurethane resin containing a repeating unit having at least one polar group selected from the group consisting of --SO.sub.3 M, --OSO.sub.3 M, and --PO(OM').sub.2, wherein M and M' have the same meanings as defined above;
• the ratio between the vinyl chloride copolymer and the polyurethane resin being in the range of from 85:15 to 10:90 by weight.
