Abstract

PURPOSE:To improve durability by incorporating a vinyl copolymer having an epoxy group in the molecule and a polyurethane resin having a tertiary amine in the molecule as a binder into a magnetic layer. CONSTITUTION:The vinyl copolymer having the epoxy group in the molecule and the polyurethane resin having the tertiary amine in the molecule are incorporated as the binder into the magnetic layer. The vinyl copolymer having the epoxy group to be used as the binder consists essentially of the vinyl compd. which is formed by copolymerizing the epoxy group to be introduced therein in order to form a crosslinking structure and a monomer having double bonds copolymerizable with the vinyl compd. The good crosslinking structure is thereby formed and the binder having the extremely outstanding durability is obtd.
