Abstract:
A color negative film which comprises a support, at least one blue-sensitive, yellow-coupling silver halide emulsion layer, at least one green-sensitive, magenta-coupling silver halide emulsion layer, and at least one red-sensitive, cyan-coupling silver halide emulsion layer, wherein at least one of the color-sensitive silver halide emulsion layers contain at least two sub-layers of differing photographic sensitivity, and said coupler application rate in the most highly sensitive layer of the color sensitive silver halide emulsion layer, of which there is at least one, and contain at least two sub-layers of differing photographic sensitivity, is no more than 0.05 mmol/m.sup.2 and a compound selected from the group consisting of(a) a development-promoting compound,(b) an electron transfer agents (ETAR) couplers and(c) affinity for silver (ACR) couplers,is used in the same or an adjacent layer, which compound, on reaction with the developer oxidation product (DOP), releases a development-promoting compound from the group of ETAR or of binding groups having an affinity for silver (ACR).
