Manually actuated dispensers and kit for roomlight processing of black-and-white photographic elements

A processing kit comprising:

• a black-and-white photographic silver halide element comprising a support having thereon one or more layers, at least one of said layers being silver halide emulsion layer;
• said element further comprising:
• in one of said layers, a microcrystalline particulate dye that absorbs electromagnetic radiation in the visible and UV portions of the spectrum and is decolorized upon contact with a fixing agent other than a sulfite;
• and in each silver halide emulsion layer, a desensitizer that reduces sensitivity of the silver halide emulsion layer to electromagnetic radiation in the visible portion of the spectrum by trapping electrons generated by exposure to that electromagnetic radiation;
• a first vessel containing a black-and-white developing composition comprising of about 0.1 to about 0.5 mol/l of a black-and-white developing agent;
• and from about 0.25 to about 0.7 mol/l of sulfite, and having a first manually actuated dispenser for dispensing said developing composition;
• a second vessel containing a fixing composition composition comprising from about 0.5 to about 2 mol/l of a fixing agent other than a sulfite and having a second manually actuated dispenser for dispensing said fixing composition;
• and
• a container including a holder for holding at least one of said photographic elements after exposure and further including an inlet through which said first and second dispensers dispense developing and fixing compositions into contact with said exposed element to develop and fix said element;
• wherein said first and second dispensers dispense fluid from the top of said vessels and including packaging for holding said first and second vessels in close proximity to each other to facilitate dispensing of said processing fluids.
