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.
