ABSTRACT:
A magnetic recording medium which comprises a magnetic layer is prepared by a dispersion of a powder of a ferromagnetic material in a binding material which is a macromolecular compound comprising an epoxy group, followed by addition to the dispersion of a silane compound comprising an amino group or a thiol group. A low viscosity magnetic coating material in which a fine powder of magnetic material is dispersed with excellent stability can thus be prepared. The recording medium prepared by using the coating material exhibits excellent magnetic characteristics, excellent durability and excellent running properties under variety of environmental conditions with desirable stability.
