ABSTRACT:
A color photographic element for use with a latent or silver image intensification or amplification method which incorporates a blocked color developing agent. The color photographic element includes at least one silver halide emulsion layer which includes at least about 70 mole percent chloride and has a concentration of silver within the range of about 0.1 mg/m.sup.2 to 2000 mg/m.sup.2. The blocked color developing agent is capable of being unblocked during photographic processing by means of reaction with a dinucleophile reagent. A preferred dinucleophile reagent is hydrogen peroxide, which also acts as an oxidant in the latent or silver image intensification method.
