Abstract: The invention creates a selective oxygen barrier around individual coupler or other photographically active particles by surrounding each particle with a layer of water applicable oxygen barrier polymer such as polyvinyl alcohol (PVA), which will also act as a steric barrier to coalescence of the particles. Photographic products formed with such materials are more dye stable.

Abstract: A photographic element is disclosed comprised of a support and at least one layer containing a photographic imaging dye or its precursor. The imaging dye is chosen to have an absorption peak below 590 nm. An azomethine dye having an absorption peak above 700 nm is associated with the imaging dye or its precursor within the photographic layer. The azomethine dye reduces the rate of fading of the imaging dye upon exposure to visible light. A process for stabilizing a photographic dye image is also disclosed.
