  • Patent number: 6395462
    Abstract: Specific aromatic compounds having an extended planar &pgr; system are useful as spectral sensitizing dye stain reducing agents in photographic processing compositions and methods for providing color or black-and-white images in various photographic silver halide materials. These compounds are devoid of diaminostilbene fragments or fused triazole nuclei. They are particularly useful in fixing and bleaching compositions in the processing of color photographic silver halide materials, but can also be used in various other processing compositions.

  • Patent number: 6248511
    Abstract: Color reversal photographic films are processed using a reversal solution comprising stannous ion and a quaternary ammonium compound as the sole microbial control agent, to reduce formation of visible biogrowth. The quaternary ammonium compound is present at very low concentrations of 1 to 20 ppm, and is preferably myristyltrimethyl ammonium bromide because it avoids precipitates with components that may leach out of some processed films.
