    摘要: A silver halide photographic element, and a method of making such an element, comprising a tabular grain silver halide emulsion containing at least one green spectral sensitizing dye of formula I, and at least one green spectral sensitizing dye of formula II: wherein R1 and R2 may be the same or different and are selected from substituted or unsubstituted C1 or C2 alkyl, substituted or unsubstituted C1 or C2 alkoxy, halogen, substituted or unsubstituted amido, or carbamoyl or substituted or unsubstituted aryl, provided that R1 and R2 are not both aryl, and the benzo back rings may optionally be further substituted; X3 is a substituted or unsubstituted C1 to C3 alkyl or alkenyl; X1 and X2 are acid or acid salt substituted C1 to C6 alkyl or alkenyl which may be further substituted or unsubstituted; M+ is a positive ion as required to balance the charge; where R3 and R4 may be the same or different and represent substituted or unsubstituted alkyl or alkenyl of 1 to 4 carbon atoms; R5 and R6 may be the same or different and both represent strong electron withdrawing groups; R8 and R9 are independently hydrogen, halogen, or a substituted or unsubstituted methyl or ethyl, or a strong electron withdrawing group; X4 and X5 are substituted or unsubstituted C1 to C6 alkyl or alkenyl at least one of which has an acid or acid salt substituent; N+ is a positive ion as needed to balance the charge.

    摘要: A silver halide photographic element comprises a silver halide emulsion layer sensitized with a sensitizing dye of Formula I: ##STR1## wherein each of X.sub.1 and X.sub.2 is an oxygen atom, a sulfur atom, or a selenium atom, with the proviso that one of X.sub.1 and X.sub.2 is an oxygen atom and the other is a sulfur or selenium atom; V.sub.1 and V.sub.2 together or V.sub.2 and V.sub.3 together represent the atoms necessary to complete a fused benzene ring; each of V.sub.4 and V.sub.5 is independently a hydrogen or halogen atom, or an alkyl, alkoxy or aryl group; R.sub.1 is an acid substituted alkyl group; R.sub.2 is a 2-sulfoethyl group; and M is a counterion as necessary to balance the charge.
