ABSTRACT:
A color photographic process which comprises processing silver halide color photographic materials using a color developer containing a 2-alkyne-1-ol represented by the general formula: ##STR1## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an alkyl group, a hydroxyalkyl group, an aminoalkyl group, a carboxyalkyl group, or a formylalkyl group, and R.sub.1 and R.sub.2 may be the same or different.
By using the above compound in a color photographic process, the speed of color development can be effectively promoted without increasing fog, and, further, the stability of the color developer is improved.
