This invention provides a photographic element containing a polymer layer which reflects a development inhibitor or its precursor released from a DIR compound thereby retarding the diffusion of the development inhibitor to another layer. The polymers used in the barrier layer contain from 1 X 10⁻⁵ to 4 X 10⁻³ ion forming functional groups. The preferred polymers comprise repeating units of the formula -(A)m-(B)n-with A derived from a hydrophobic monomer and B derived from an ionic hydrophilic monomer with the more preferred monomers being acrylates, methacrylates, acrylamides and methacrylamides. The invention also provides a method of processing a photographic element containing such a barrier layer.
