Abstract

PURPOSE: To spectrally sensitize the red and blue regions of the titled emulsion to a high extent, by adding an oxacarbocyanine dye and a cyanine dye in combination in a supersensitizing amount.
CONSTITUTION: To a silver halide photographic emulsion is added in a supersensitization amount one or more of supersensitizing dyes represented by formula I in which Z1 and Z2 are each an atomic group needed to form a (benzo- or naphtho- or simple)-(oxazole, thiazole, or selenazole) ring, but Z1 and Z2 do not represent oxazoles simultaneously; R1, R2 are each an aliphatic group optionally substituted and optionally intercepted by -O- or -S-; R° is H, alkyl, or aralkyl; X1 - is an acid anion; and m is 1 or 2, in combination with one or more of a supersensitizing dye represented by formula II in which Z3, Z4 are each an atomic group needed to form a pyrroline, pyridine, indolenine, benzimidazole, oxazoles, thiazoles, or selenazoles; R3, R4 are as R1, R2; X1 - is an acid anion; and n is 1 or 2.
