Silver halide photographic sensitive material having excellent color reproducibility

Abstract

Abstract PURPOSE:To obtain a high color developing density and sufficient max. density and to improve color reproducibility and preservable property by incorporating specific cyan couplers and specific non-color developable compds. into at least one layer of red photosensitive silver halide emulsion layers. CONSTITUTION:This photosensitive material contains at least one of the cyan couplers expressed by formulas I, II, etc., and at least one of the non-color developable compds. expressed by formula III in at least one layer of the red photosensitive silver halide emulsion layers. In the formulas I, II, R1 and R3 denote a hydrogen atom or substituent; R2 denotes a substituent; X denotes a hydrogen atom or the substituent to be eliminated by reaction with the oxidant of a color developing agent; n denotes 0 to 4 integer. In the formula III, RA and RB are respective hydrogen atom, alkyl group, cycloalkyl group, alkenyl group, etc. The max. absorption wavelength of cyan dye images exist sufficiently on the long wavelength side of a red spectral region and sub-absorption is small near 420nm and 550nm. The excellent color reproducibility is thus obtd.
