摘要： The invention relates to a novel kind of anthranilic acid compound that releases a UG as a function of chemical bond cleavage according to Formula (I): Q-(AAS)-UG where UG is an useful group and is chemically bonded to (AAS); (AAS) is an anthranilic acid switching group; and Q is a group in which the bond to (AAS) is broken so that the -(AAS)-UG fragment subsequently decomposes to the free UG. In one embodiment this invention relates to a multilayer silver halide photographic element comprising a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one layer additionally contains an anthranilic acid compound according to Formula (II): G-(TG1)q-(AATG)-(TG2)p-PUG where G is a group in which the bond to the timing group is cleaved upon reaction with oxidized developer; TG1 and TG2 represent any known timing or switching group and may be the same or different; q and p are independently 0 or 1; AATG represents an anthranilic acid timing group and PUG is a photographically useful group.

摘要： The invention provides a color photographic element comprising at least one light-sensitive silver halide emulsion layer or a non silver-containing light-insensitive layer, in which at least one of these layers contains a colorless heterocyclic compound having either one or two hetero atoms in the ring or ring system, being other than an imidazole compound, that undergoes less than 10% chemical or redox reaction directly with oxidized developer and which has a partition coefficient to enable the photographic speed of the element to be increased by at least 0.03 stop without increasing granularity, compared to the same element without the compound. The heterocyclic compounds increase speed without a concomitant increase in size of the light-sensitive silver halide grains.
