Abstract
1,251,712. Photographic light-sensitive silver dye-bleach materials. EASTMAN KODAK CO. Jan. 1, 1969 [Jan. 2, 1968], No.34/69. Addition to 1,131,238. Headings G2C. A photographic light-sensitive silver dyebleach material comprises a support and has coated thereon a light-sensitive layer of which the light-sensitive component is a silver compound of a cyanine or merocyanine sensitizing dye (as defined in Specification 1,131,238) and in the same layer or in a contiguous layer at least one dye which is imagewise bleachable by the silver dye-bleach process. The silver compound is usually coated at a coverage of 0À5 mg to 10 mg of heavy metal content per sq. ft. The coloured image is produced by forming silver image(s) by physical development of a material as defined above which has been imagewise exposed, and bleaching the dye or dyes associated therewith in accordance with The silver image(s). Specification 1,251, 711 is referred to.
