ABSTRACT:
The present invention is a photographic element which includes a support having a first side and a second side, at least one light sensitive emulsion layer superposed on the first side of the support, a transparent magnetic layer superposed on the second side of the support. The transparent magnetic layer includes magnetic particles and a film forming binder. An outermost abrasive lubricant layer overlies the transparent magnetic layer. The outermost abrasive lubricant layer is formed from a non-aqueous coating composition of a composite wax particle, an abrasive particle and an organic solvent. The composite wax particle is composed of a wax phase having a wax having a melting point of greater than 30.degree. C. the wax being greater than 80% by weight of the wax phase and a non-crosslinked polymer phase free of chemically bonded acid groups.
