Abstract: A photographic imaging element comprising a support having on a front side thereof a silver halide imaging layer and an outermost protective overcoat layer comprising a film-forming binder, and on the backside thereof an outermost protective backcoat layer comprising a film-forming binder; the protective overcoat and backcoat layers each comprising a lubricant present in an amount of at least 5 mg/m 2 and permanent matting agent having a T g of at least 40 °C and an average particle size of from 0.5 to 3 micrometers; and at least one of the protective overcoat layer or the protective backcoat layer further comprising crosslinked elastomeric polymer matte particles that have a T g of 20 °C or less and an average particle size of at least 90 % of or greater than that of the permanent matting agent particles in an amount which is less than the total level of permanent matting agent particles.
