Abstract
PURPOSE:To obtain excellent durability by using a vinyl copolymer having an epoxy group and polyurethane having a carboxyl group as a binder. CONSTITUTION:The vinyl copolymer having the epoxy group in the molecule and the polyurethane resin having the carboxyl group in the molecule are incorporated as the binder into a magnetic layer. The vinyl copolymer having the epoxy group to be used as the binder consists mainly of a vinyl compd. which is formed by copolymerization of the epoxy group 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 without being affected by moisture at the time of reaction and the excellent durability is obtd.
