摘要： A silver halide color photogtaphic material is disclosed, comprising a support having provided thereon at least one silver halide emulsion layer containing a cyan coupler, at least one silver halide emulsion layer containing a magenta coupler, and at least one silver halide emulsion layer containing a yellow coupler, in which said cyan coupler-containing emulsion layer contains (l) at least one of a specified type of cyan coupler, and (2) a high-boiling organic solvent in an amount of not more than 30% by weight based on the total amount of said specified type of cyan coupler. The photographic material exhibits improved sharpness without being accompanied by reduction in color developability or precipitation of crystals. These effects can be enhanced by using 2-equivalent polymeric magenta couplers in combination.

摘要： Photographic couplers comprise a naphtholic coupler moiety capable of forming a red or infrared absorbing dye upon oxidative coupling and comprising (i) an optional coupling-off group in the coupling position, (ii) a group, in the position ortho to the hydroxy group, which is represented by the formula:
- -R wherein R is a substituent which enables the dye formed upon oxidative coupling to absorb in the red or infrared region of the spectrum without undesired dye instability, and (iii) a group Y in the 5-position of the naphtholic coupler moiety which is capable of promoting red or infrared dye formation, the group Y having sufficient bulk to provide a bathochromic shift in the absorption of the resulting red or infrared dye. These couplers are useful in photographic materials and processes enabling formation or red and infrared absorbing dyes.-

摘要： There is disclosed a coupler for photography represented by the formula:
wherein R 1 represents a branched alkyl group having 3 to 5 carbon atoms: R 2 represents an aryl group; X represents a divalent linking group; Ar represents an aryl group; and Z is a hydrogen atom or a group eliminable through the coupling reaction with the oxidized product of an aromatic primary amine type color developing agent, and a light-sensitive silver halide photographic material comprising the same. The coupler mentioned above is not only excellent in solubility in organic solvents, but also can be easily purified, thus being capable of exhibiting excellent characteristics with respect to spectral absorption characteristics, sensitivity, colour density, color staining as well as with respect to image storability such as light resistance, heat resistance and humidity resistance.-
