A polymeric binder system useful for a magnetic recording medium, the polymeric binder system and comprising a hard resin component comprising a nonhalogenated vinyl copolymer and a soft resin component comprising a polyurethane having a phosphonate diester group. The binder system is useful for preparing the magnetic layer and/or backside coating of magnetic recording media, in order to provide media that demonstrate an improved combination of such as modulus, Tg, and smoothness. |
