  • Patent number: 4920040
    Abstract: A silver halide light-sensitive photographic material for a laser light exposure is disclosed. The material comprises a support having thereon at least one light-sensitive silver halide emulsion layer containing silver halide grains therein and a layer adjacent thereto, wherein said silver halide grains are spectrally sensitized with a dye represented by the following formula I, at least one layer of said silver halide emulsion layer and said adjacent layer contains a fluorine-containing ionic surfactant, a non-ionic surfactant and an inorganic salt; ##STR1## The material of the invention excels in each of sensitivity, gradation and maximum density, and exhibits good coloration.

  • Patent number: 4847187
    Abstract: Disclosed is a light-sensitive silver halide photographic material comprising at least one silver halide emulsion layer on at least one side of a support and at least auxiliary layer adjacent to the silver halide emulsion layer, the silver halide emulsion layer containing a surface latent type silver halide emulsion and a silver halide emulsion having fog internally of the grains, and the auxiliary layer containing a compound represented by the formula (I) shown below:RfSO.sub.3 M Formula (I)wherein Rf is a substituted or unsubstituted alkyl group or a substituted or unsubstituted aralkyl group, containing at least 3 fluorine atoms, and M represents hydrogen atom, an alkali metal or ammonium group.According to the present invention, a light-sensitive silver halide photographic material improved in antistatic performance and also improved in storability without accomplaniment of lowering in sensitivity, which can give images with sensitivity, high contrast as well as high covering power is provided.
