Abstract:
A photographic element is disclosed comprising a support bearing at least one light sensitive silver halide emulsion layer comprising a dispersion of a dye-forming coupler and a water-insoluble polymer, wherein the polymer has a glass transition temperature of less than 75. degree. C. and is formed from at least 30 wt % monomer units which provide the polymer with functional groups that are hydrogen bond donors. The combination of such relatively low T. sub. g polymers with couplers in photographic elements leads to both decreased pressure sensitivity and improved image-dye light stability, as well as a decreased tendency toward dye smear or thermal induced change. The advantages of the invention are particularly useful for yellow coupler dispersions used in photographic color paper elements on reflective supports, although they will also be useful for motion picture print film and other projection or display films on transparent or diffuse supports.
