    摘要: The invention relates to a photographic element comprising a support and a silve halide emulsion layer wherein the silver halide emulsion contains at least one absorber dye and at least one sensitizing dye. The wavelength of maximum absorbance of said absorber dye and the wavelength of maximum sensitivity of the emulsion provided by the spectral sensitizing dye are substantially the same. The emulsion is chemically sensitized with a stable and water soluble AuI) complex. This provides manufacturing improvements, improved detail and sharpness, improved dodging and burning and lower cost without an unwanted increase in heat sensitivity.
