摘要： A method for producing a silver halide photographic light-sensitive material having on a support thereof at least one layer formed of an emulsion containing light-sensitive silver halide particles sensitized by a sensitizing dye comprising the steps of adding a first sensitizing dye to an emulsion containing silver halide particles, during the chemical ripening of the silver halide particles, to sensitize the silver halide particles; adding a second sensitizing dye to the emulsion containing the sensitized silver halide particles, after the chemical ripening of the silver halide particles, to form a coating liquid; and coating a support with the coating liquid to produce a silver halide photographic light-sensitive material.
