The present invention 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 hydrophobic groups, the hydrophobic groups having a logP.sub.(calc) greater than a logP.sub.(calc) of the ethylenically unsaturated monomer by at least 1 unit, and polymerizing said droplets so that the polymerized droplets have a size of less than 400 nm. 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.
