ABSTRACT:
A flexible magnetic recording media having superior peel strength is disclosed. The magnetic recording media comprises a primer coated polyester film which has been overcoated with a coating comprising ferromagnetic particles dispersed in a polymeric binder. The primer coating is preferably sodium oleate which has been in-line coated onto polyethylene terephthalate film. The ferromagnetic particles are preferably chromium dioxide particles. The polymeric binder is preferably a polyurethane reaction product of (A) a hydrolytically stable difunctional alcohol, (B) a chain extender, and (C) an aromatic diisocyanate.
