    摘要: The present invention is also directed to a method of photoprocessing a photographic imaging element having a processing-solution-permeable overcoat that comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble hydrophilic polymer. During photoprocessing, a surface-active water-soluble hydrophilic polymer is leached into a photoprocessing solution. However, foaming due to the hydrophilic polymer in the photoprocessing solution is prevented by the presence of a non-ionic surfactant having an HLB of less than 12.
