摘要： A presensitized plate from which a lithographic printing plate is to be prepared, comprising a support having provided thereon a non-silver light-sensitive layer comprising an O-quinonediazide compound and a silver halide light-sensitive layer in this order, said silver halide light-sensitive layer containing a specific sensitizing dye. The presensitized plate is specifically high in sensitivity to a light of the wavelength in the range of 480 nm to 520 nm, and therefore it can be handled even under the lighter safe light.

摘要： A silver halide photographic emulsion is disclosed. The emulsion includes a silver halide emulsion which has dispersed therein at least three types of sensitizing dyes. The emulsion includes at least one dye represented by the formula (I), at least one dye represented by the formula (II) and at least one dye represented by the formula (III). Each of the structural formulae and their substituents are defined within the specification. The resulting silver halide photographic emulsion shows a small decrease in the inherent sensitivity of the silver halide due to the sensitizing dye used.
