Yellow dye-containing developing composition and its use in two-stage processing of roomlight handleable black-and-white photographic elements

摘要

Roomlight processing of black-and-white photographic elements comprises processing an imagewise exposed black-and-white photographic silver halide element with an aqueous black-and-white developing composition in a process container, and then adding a fixing composition to the container. A black-and-white image is provided by: (A) processing an imagewise exposed black-and-white photographic silver halide element with an aqueous black-and-white developing composition in a process container. The developing composition has: (i) a pH of 10 - 12.5; (ii) 0.1 - 0.5 mol/l of a black-and-white developing agent; (iii) at least 1 wt.% of a water-soluble colorant with a maximum absorption wavelength of 350 - 500 nm; and (iv) 0.1 - 0.7 sulfite; (B) introducing into processing container within 20 seconds of the beginning of (A), a fixing composition comprising 0.2 - 8 mol/l of a fixing agent other than sulfite, and continuing processing for an additional 40 seconds. The total time for the method is 90 seconds. The element comprising a support having one or more layers is such that at least one of the layers is a silver halide emulsion layer.
