ABSTRACT:
Novel pyrazoloazole dye-forming couplers contain on the azole ring a group containing a carbon atom bonded directly to the azole ring and wherein this carbon atom is bonded directly to a nitrogen atom in the group. Such couplers provide advantageous bathochromic hue shift in dyes formed from the couplers. These couplers are useful in photographic silver halide materials and processes.
