ABSTRACT:
A magnetic coating composition for use in the production of a magnetic recording material is described. The composition is comprised of at least ferromagnetic metal powder and/or ferromagnetic alloy powder and nitrocellulose having an average degree of polymerization of from 10 to 55, or at least ferromagnetic metal powder and/or ferromagnetic alloy powder, nitrocellulose having an average degree of polymerization of from 10 to 55, and at least one polymeric binder. This magnetic coating composition has excellent dispersibility of the magnetic powder, and can provide a magnetic recording material which has excellent surface smoothness and orientation ratio, as well as excellent durability.
