Abstract (en)
[origin: EP0269227A2] There is disclosed a method for common development processing of two kinds of light-sensitive silver halide photographic material which comprises the step of development processing an internal latent type direct positive light-sensitive silver halide photographic material and a negative-type light-sensitive silver halide photographic material in the same development processing bath, and the step of applying whole surface exposure on the internal latent type direct positive light-sensitive silver halide photogrpahic material during development processing of the internal latent type direct positive light-sensitive silver halide photographic material, characterized in that the developing processing solution contains a compound represented by the formula (A) shown below: <CHEM> wherein R1 and R2 each represent hydrogen atom or an alkyl group having 1 to 5 carbon atoms which may have a substituent or may be combined with each other to form a heteroxyclic ring.
