摘要： PROBLEM TO BE SOLVED: To provide a color photographic recording material with which satisfactory sensitivity is achieved at a very low silver application rate with no impairment of color reproduction on the photograph illuminated with fluorescent light and with no particularly observable green cast.
SOLUTION: The color photographic recording material has a support and at least two each of blue-, green- and red-sensitive silver halide emulsion layers of differing photographic sensitivity, wherein the silver application rate is less than 3.2 g of silver per m
2 , camera sensitivity is at least ISO 100, and when an exposure is made of a gray card of density 0.6 with fluorescent light of light color 21, the recording material gives rise to a hue on the print which, in CIELab values, meets the conditions a>0 and 0

摘要： PROBLEM TO BE SOLVED: To provide a photographic element with increased photographic sensitivity of a silver halide emulsion. SOLUTION: The negative silver halide photographic element comprises a support and a silver halide image forming layer comprising a photosensitive silver halide image forming emulsion, wherein the silver halide image forming layer further comprises a separately deposited, non-image-forming, intentionally fogged fine grain emulsion and an electron transfer agent releasing compound of the formula (I): CAR 1 -(L) n -ETA (where CAR 1 is a carrier moiety capable of releasing -(L) n -ETA by a reaction with an oxidized developing agent; L is a divalent linking group; n is 0, 1 or 2; and ETA is a releasable electron transfer agent).

摘要： PURPOSE:To enhance sensitivity and color reproducibility by incorporating compds. capable of releasing development inhibitors different in diffusivity upon reacting with the oxidized product of a color developing agent, in a silver halide emulsion layer except that having the max. sensitivity among plural silver halide emulsion layers. CONSTITUTION:Photosensitive layers consisting of plural silver halide emulsion layers different in photosensitivy but substantially same in color sensitivity are formed on a support. At least 2 kinds of compds. capable of releasing development inhibitors different in diffusivity from each other upon reacting with the oxidized product of a color developing agent are incorporated in said silver halide emulsion layer except that highest in photosensitivity of all of them. Said photosensitive layers of plural silver halide emulsion layers different in photosensitivity but same in color sensitivity mean photosensitive layers having blue, green, and red sensitive layers in an ordinary color photographic system. Sensitivity and color reproducibility can be enhanced by combining said compds. capable of releasing development inhibitors different in diffusivity.
