Abstract

PURPOSE:To provide a magnetic recording medium having excellent durability by using a resin having an epoxy group as a binder and forming a magnetic layer essentially consisting of the binder crosslinked by polythiol and ferromagnetic powder on a nonmagnetic base. CONSTITUTION:The binder used in the magnetic recording medium constituted by forming the magnetic layer 2 essentially consisting of the ferromagnetic powder and the binder on the nonmagnetic base 1 contains the resin having the epoxy group and is crosslinked by the polythiol. The resin contg. the epoxy group is prepd. by polymerizing a monomer having the epoxy group and copolymerizable double bonds and other copolymerizable monomer. A compd. having the epoxy group is coated as the binder on the magnetic layer and thereafter, the compd. having the epoxy group is crosslinked by using the polythiol, by which the durability as the binder is extremely improved. The magnetic recording medium having the excellent durability is provided by using such binder.
