The present invention also is a photographic element which includes a support, at least one silver halide emulsion layer; and at least one layer containing a binder and polymer particles. The polymeric particles are prepared by the process of mechanically forming droplets having a size less than 400 nm of an ethylenically unsaturated monomer having a logP.sub.(calc) greater than 4, preferably greater than 6, and polymerizing said droplets so that the polymerized droplets have a size of less than 400 nm.

A hydrophilic colloid is added to the aqueous medium in an amount sufficient to render the polymer partice compatible with the hydrophilic binder. The droplets are polymerized to a size of less than 400 nm. The present invention is also a photographic element which includes a support, at least one silver halide emulsion layer, and a light-insensitive protective overcoat. The light insensitive protective overcoat includes a hydrophilic binder and polymer particles having a glass transition temperature of at least 70.degree. C.
