发明名称 Dye compounds and photographic elements containing such dyes
摘要 A silver halide photographic element comprising a sensitizing dye of the formula: <IMAGE> wherein: X1, X2, n, L, L2, R1 and R2 are as defined in the specification; Z1 represents Ar1-(L1) m, where Ar1 is a substituted or unsubstituted aromatic group, L1 is a linking group, m is 0 or 1, and the LOGP(A) of a molecule having a structure A corresponding to a portion of the dye structure A <IMAGE> is no more than 90% of LOGP(A'), where A' is the same as A except Z1 is replaced with unsubstituted phenyl, provided that L1 is not -CO- when X1 or X2 is S or Se; and W1 is a counterion as needed to balance the charge of the molecule.
