ABSTRACT:
An image-forming method is disclosed. The method includes providing a silver halide color photographic material and imagewise exposing that material. The exposed material is color developed in the presence of a compound capable of reacting with or adsorbing a silver halide. The material is developed within a mono-bath intensifying developing solution which includes hydrogen peroxide or a compound capable of releasing hydrogen peroxide and a color developing agent. The solution substantially excludes the presence of bromide ions and iodide ions. The compound capable of reacting with or being absorbed into silver halide is a nitrogen-containing heterocyclic compound which has been found to be very useful in the image-forming method to obtain high color density with materials containing a small amount of silver halide.
