ABSTRACT:
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 about 1.times.10.sup.-5 to about 4.times.10.sup.-3 ion forming functional groups. The preferred polymers comprise repeating units of the formula --(A).sub.m -(B).sub.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.
