  • Patent number: 6482579
    Abstract: Color negative photographic elements can be effectively processed to provide negative color images using bleaching or bleach-fixing compositions in which the primary bleaching agent is a ferric complex of 1,3-propylenediaminetetraacetic acid or a salt thereof. Any potential precipitation of the bleaching agent is inhibited by the presence of at least 0.005 mol/l of an organic polyphosphonic acid, an aminopolysuccinic acid, or a polycarboxylic acid containing at least one hydroxy group as a compound. This compound can be added directly to the bleaching or bleach-fixing composition or introduced from carryover from a previous photoprocessing step.
    Type: Grant
    Filed: February 5, 2001
    Date of Patent: November 19, 2002
    Assignee: Eastman Kodak Company
    Inventors: Jon A. Kapecki, Harry J. Price, David M. Braitsch
  • Patent number: 6479223
    Abstract: A method of producing a photographic image in an imagewise exposed photographic material comprising one or more silver halide emulsion layers comprises applying to the material in an imagewise manner a developer solution containing a silver halide developing agent wherein the amount of solution applied depends on the image density to be produced, removing unreacted developing agent from the material or inactivating unreacted developing agent in the material by means other than immersion of the material in a liquid in a tank.

  • Patent number: 4782012
    Abstract: Photographic elements and processes are described which employ compounds capable of releasing, as a function of silver halide development, a deactivatable development inhibitor to provide a combination of desirable sensitometric results. The deactivatable development inhibitor has the structure: ##STR1## wherein X is alkylene of 1 to 3 carbon atoms;R is alkyl of 1 to 4 carbon atoms; andthe sum of the carbon atoms in X and R is 5 or less.

  • Patent number: 4414307
    Abstract: Sparingly-soluble alcohols, such as benzyl alcohol, which function to enhance photographic coupling efficiency are incorporated in photographic color developing solutions by the use of solid water-soluble alcohol-precursor compounds. The solid precursor compounds, which can be advantageously utilized as components of an all-solid photographic processing kit, comprise a solubilizing group which is cleaved by the alkaline environment of the color developing solution to form the sparingly-soluble alcohol. Examples of such solid precursor compounds which are especially advantageous in the preparation of color developing solutions are the alkali metal monobenzylcarbonates and the alkali metal monobenzylsulfites.
