  • Patent number: 6645705
    Abstract: The present invention is a photographic element which includes a support, at least one silver-halide emulsion layer superposed on the support and a processing-solution-permeable overcoat overlying the silver-halide emulsion layer that becomes water-resistant in the final product, without requiring lamination or fusing. The presence, in the coating composition, of a compound comprising a blocked copolymer of ethylene oxide and propylene oxide has been found to improve wet durability, prevent the retention of iron, and improve the conversion of the overcoat to a water-resistant layer during processing. The present invention is also directed to a method of making a photographic print involving developing the photographic element.

  • Patent number: 6586165
    Abstract: The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflective layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.

  • Patent number: 6572677
    Abstract: The present invention relates to the use of fine metal particles for the recovery of silver from a silver-bearing photographic waste solution. In particular, the metal particles are encapsulated in a hydrophilic colloid that allows for the permeability of water and silver ions. When contacted with the silver-bearing photographic waste solution, the hydrophilic colloid will imbibe water and swell. At the same time, the silver ions can permeate the colloid matrix and come into contact with the metal particles, preferably iron particles, at which point a metal—metal exchange reaction takes place.
