ABSTRACT:
By means of a development intensification process for processing color photographic silver halide materials, the silver halide emulsions of which contain more than 90 mol. % of AgCl and less than 0.8 g of silver halide per m.sup.2 (stated as the equivalent quantity of AgNO.sub.3), short processing times accompanied by stable replenishment rates are obtained if at least one compound of the formulae (I), (II) or (III) is used as the developer substance in a quantity of 0.002 to 0.04 mol/l of developer solution ##STR1## in which R.sub.1 to R.sub.3, R.sub.10 to R.sub.17, R.sub.21 to R.sub.23, m, n and Y have the meaning stated in the specification.
