  A photographic element containing a temporary barrier layer between reactants and polymeric compositions useful therein are disclosed. The compositions comprise a mixture of (1) from 5 to 95 percent by weight of a polymer comprising from 55 to 85 percent by weight of vinylidene chloride, 5 to 35 percent by weight of an ethylenically unsaturated monomer, and optionally from 0 to 20 percent by weight of an ethylenically unsaturated carboxylic acid, and (2) from 95 to 5 percent by weight of a polymeric carboxy-ester-lactone. A barrier formed from such composition is particularly useful as a process timing layer in color image transfer photographic elements.

  A photographic element for use in two-sheet diffusion transfer photography is described which contains a support, a neutralizing layer, a timing layer, a vinylidene chloride polymeric layer, a polymeric primer layer, and at least one silver halide emulsion layer having a dye image-providing material associated therewith. The vinylidene chloride polymeric layer and the polymeric primer layer prevent unwanted transfer of portions of the emulsion layer to the image-receiving layer when the receiving layer and photographic element are peeled apart. The polymeric primer layer can be either an ionic vinyl polymer or an ionic polyester.
