Transparent lubricious overcoat containing fluoropolymer microparticles for transparent magnetic recording layer for photographic element

摘要

The present invention is a photographic element which includes polyester film support and at least one light-sensitive silver halide layer on a front side of the support. An antistatic layer is superposed on the backside of the support. A transparent magnetic recording layer is superposed on the backside of the support. A protective lubricating overcoat layer is superposed on the backside of the support, the antistatic layer being closest to the support and the overcoat layer being furthest from the support. The protective lubricating overcoat layer includes fluorinated ethylene polymer particles having a mean particle size of from 0.01 to 0.5 mu m, abrasive particles having a Mohs scale hardness of 6 or more and a median diameter of from 0.1 to 0.4 mu m, and a transparent binder.
