Abstract (en)
[origin: WO9210789A1] A method of developing an imagewise exposed silver halide colour material to provide acceptable sensitometric results with reduced variability which comprises carrying out colour development in the presence of one or a combination of black-and-white silver halide developing agents which reduces the variability of the sensitometric results caused by changes in process variables, preferably 1-(4-methoxyphenyl)-3-pyrazolidone, 1-(3,4-dimethoxyphenyl)-3-pyrazolidone, or 1-phenyl-4-n-pentyl-pyrazolidone.
