PHOTOGRAPHIC RECORDING MATERIAL CONTAINING POLYMERS WHICH COORDINATE WITH METAL IONS

摘要

Photographic recording material containing polymers which coordinate with metal ions, complexes produced thereby and novel polymers are disclosed. The recording material comprises a support, a photosensitive silver halide emulsion layer, an image dye or dye-forming material and a layer containing a dye mordant. The mordant layer has associated therewith a source of metal ions and a polymer which is capable of forming a complex with metal ions. The complex provides improved light stability to image dyes. The image dyes are preferably dye ligands or dye ligand forming materials.
