摘要： A method of sensitizing a silver halide emulsion comprises the steps of:a) forming a co-dispersion of a first sensitizing dye and a second sensitizing dye in an aqueous medium, wherein the peak absorptance of the second dye is at least 10 nm different from the peak absorptance of the first dye, and wherein the ratio of the first dye to the second dye is from about 0.1 to 20; andb) incorporating the resulting co-dispersion in a silver halide emulsion.

摘要： A photographic element having a silver halide emulsion spectrally sensitized to blue light by a dye of formula (I) to have a maximum blue sensitivity at less than 485 nm. The dye allows the element to have good color reproduction while still providing good speed response despite the shorter blue sensitivity. Formula (I) is: ##STR1## wherein: X and X' each independently represent the atoms necessary to complete a thiazole, benzothiazole, naphthothiazole, oxazole, benzoxazole, naphthoxazole, selenazole, benzoselenazole, naphthoselenazole, imidazole, benzimidazole, or naphtho-imidazole, and X may be further substituted and X' substituted or unsubstituted;Z.sub.1 represents a pyrrole, furan or thiophene containing group;R.sub.1 and R.sub.2 each independently represent substituted or unsubstituted hydrocarbon containing 1 to 10 carbon atoms; andA represents a counter-ion as needed to balance a charge of the molecule.
