Novel pyrazoloazole dye-forming couplers comprising (I) at least one polyether group (A) comprising at least two ether (-O-) groups and (II) having between the group (A) and the pyrazoloazole nucleus a linking group (L) that is capable of increasing the reactivity of the coupler to enable improved dye images in a photographic element and process. These couplers are useful in photographic silver halide elements and processes.
