摘要： A novel blocked photographically useful compound comprises a new blocking group that (a) comprises two electrophilic groups, the least electrophilic of which is bonded directly or through a timing group to the photographically useful group (PUG) of the compound, (b) is capable of reacting with a dinucleophile reagent, and (c) has the two electrophilic groups separated from each other by a bond or unsubstituted or substituted atom that enables nucleophilic displacement to occur with release of PUG when the compound is reacted with a dinucleophile reagent. Such a blocked photographically useful compound is useful in a photographic material and process to provide increased stability and enable more rapid release of the photographically useful group upon reaction with a dinucleophile reagent.

摘要： A silver halide photographic negative has a red sensitive layer containing a coupler which reacts with oxidized color developer to form a cyan dye, a blue sensitive layer containing a coupler which reacts with oxidized color developer to form a yellow dye, and a green sensitive layer containing a coupler which reacts with oxidized color developer to form a magenta dye. The coupler in the green sensitive layer produces a magenta dye which has relatively low density in the 560-590 nm range as compared with magenta dyes produced by pyrazolotriazole type couplers or 1-phenyl-3-acylamino-5-pyrazolone couplers. The element additionally has an inert dye present, preferably positioned below the green sensitive layer containing the foregoing coupler. The inert dye has a peak absorption between 560-590 nm so that the negative has a ratio of density at 580 nm to density at 550 nm, both as measured at neutral midscale exposure, which is greater than exhibited by the element absent the inert dye.

摘要： A new photographic coupler comprises a coupling-off group bonded to the coupler at the coupling position represented by the formula:--L--NR.sup.1 --DYEwherein L is a linking group; NR.sup.1 is a substituted nitrogen atom bonded to DYE that together with NR.sup.1 is a releasable dye comprising an electrically neutral chromophore. Such a coupler enables dye hue stabilization without mordanting the dye formed. Such a new coupler is useful in a photographic silver halide element and process to provide increased dye density, higher contrast dye images, and lower pH sensitivity upon processing.

摘要： A photographic element containing a dye which when released from a coupler has a sufficiently low pKa, generally less than about 5, such that the dye remains substantially or fully ionized during coating of the film and in the produced film, results in an element containing a dye which has the desired hue without the use of additional additives, such as mordants, to keep the dye ionized. The dye is also useful in photographic elements without release from a coupler, for example, as a filter dye.
