Inhibitor barrier layers for photographic materials |
摘要 |
A photographic element comprises a support, a silver halide emulsion layer and a layer containing a polymeric scavenger for development inhibitors. The movement of development inhibitor anions from layer to layer in a film, out of the film, or into the film from processing solutions, can be controlled by the presence of the polymeric scavenger layer.
