    摘要: A color image forming process comprising processing a photographic element having silver image-wise distributed therein in the presence of a specific type of complexing agent, an oxidizing agent which is peroxo acid or salt thereof, and a dye or dyes, to oxidatively bleach the dye or dyes. By the process of this invention, color images which are stable to light, heat and moisture are obtained using photosensitive materials containing a reduced amount of silver salt or silver without using chemicals causing pollution problems for the processing.

    摘要: Disclosed herein are aqueous and nonaqueous photographic bleaching solutions and photothermographic elements comprising stable free radical nitroxyl bleaching agents. These agents are capable of bleaching preformed of developed metals, such as silver, in both aqueous and nonaqueous photographic materials. They do not adversely affect the photographic properties of radiation sensitive emulsions and can be thermally activated in a dry photothermographic process.

    摘要: A method of preparing a bleached phase hologram comprising bleaching a silver image of an amplitude hologram formed in a silver halide photographic material with a bleaching solution comprising a liquid medium capable of swelling the gelatin and/or modified gelatin hydrophilic colloid of the silver halide photographic material to an extent of from about 150 to 400% and containing iodine, so as to bleach the silver image by the reaction of the iodine with the silver and the silver image of the amplitude hologram is formed by exposing a silver halide photographic material so as to form a hologram and development and fixing processing the exposed silver halide photographic material.

    摘要: A METHOD FOR EXTENDED DYNAMIC RANGE PROCESSING OF PHOTOGRAPHIC FILM IN WHICH THE EXPOSED FILM IS WEAKLY DEVELOPED IN A DILUTE SOLUTION OF SURFACE DEVELOPER. THE EMULSION SURFACE OF THE FILM IS THEN BLEACHED WITH A DILUTE SOLUTION OF BLEACH FOR A SHORT PERIOD OF TIME AND CLEARED WITH A SALT SOLUTION. THE EMULSION IS THEN DEVEL-

    OPED WITH FULL STRENGTH PHOTOGRAPHIC DEVELOPER AND STOPPED FIXED, WASHED, AND DRIED IN THE CONVENTIONAL MANNER TO PRODUCE A NEGATIVE HAVING AN EXTENSION OF THE EXPOSURE LATITUDE OF THE FILM FROM 3 ORDERS TO ABOUT 6 ORDERS.

    摘要: A bleach or bleach/fixing solution for processing photographic silver halide materials which, relative to the silver halide content of the unprocessed material, exhibit prior to the bleaching step a content of silver arising from development of at least 65 mol %, in particular for processing color reversal materials, characterized in that the solution contains at least one iron complex of propylenediaminetetraacetic acid or of &bgr;-alaninediacetic acid or a mixture of these complexes and the total concentration of the stated iron complexes in the solution is at least 0.045 and at most 0.25 mol/l and a process for processing, in which such a solution is used, is characterized by a small introduced quantity of iron complexes, a low residual silver content, a low bleaching fog value, elevated resistance to precipitation and in that the bleach solution may be rejuvenated.
