A silver halide photographic light-sensitive material is disclosed, comprising tabular grains having an average aspect ratio of diameter to thickness of 2 or more, having an average overall iodide content of 2 mol% or less, and having a surface phase containing 3 to 20 mol% iodide on the average. The emulsion is spectrally sensitized by adding a sensitizing dye represented by the following formula [I] or [II],
摘要:
Certain poly(lactic acid) and poly(glycolic acid) polymers or copolymers, and certain carbonates, lactones, lactates, lactylates, lactides, glycolates, glycolylates, and glycolides have been found to stabilize thermal-dye-bleach constructions containing a dye in association with a thermally-generated-bleaching agent. Preferably, the thermally-generatated-bleaching agent is a thermal-carbanion-generating agent such as a quaternary ammonium salt of a phenylsulfonylacetic acid or a thermal-nucleophile-generating agent such as an ammonium salt of a phenylsulfonylacetic acid. These materials have been found to be particularly effective when used in acutance and antihalation systems for photothermographic and photographic elements.
摘要:
A silver halide photographic material having at least one silver halide light-sensitive emulsion layer on at least one side of a support, wherein said silver halide emulsion layer comprises tabular silver halide grains having a grain thickness of 0.3 µm or less and accounting for at least 50% of the total projected area, and a phthalocyanine blue pigment having a maximum absorption wave length of from 640 to 700 nm is present in said silver halide emulsion layer and/or in another hydrophilic layer of the photographic material.
摘要:
Disclosed is a silver halide color photographic light-sensitive material comprising a reflective support comprising polyolefin resin coated paper and provided on one side thereof with photographic component layers comprising a hydrophilic colloidal layer containing a white pigment, a non-sensitive hydrophilic colloidal layer, and a silver halide emulsion layer, wherein at least one of said photographic component layers contains an oil-soluble dye or a colored pigment, either of which is not substantially decolorized on a photographic-processing.
摘要:
A silver halide color photographic light-sensitive material includes a support having provided thereon at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, at least one red-sensitive silver halide emulsion layer, and at least one hydrophilic colloid layer. The hydrophilic colloid layer contains a compound represented by Formula (I) below, a silver halide emulsion layer having an interlayer effect on the red-sensitive layer is also provided, and the layer with the interlayer effect contains a silver halide emulsion spectrally sensitized with a sensitizing dye represented by Formula (II) or (III) below.
摘要:
A radiation detecting element is disclosed, particularly a photographic element having a radiation detecting composition, in particular a silver halide emulsion. The composition provides the element with a wavelength of peak sensitivity, λpeaksens , and a decreasing sensitivity around λpeaksens . An absorber dye of defined characteristics is chosen, which has the effect of decreasing the change in sensitivity which the element otherwise has without the absorber dye (that is, the absorber dye increases the wavelength range over which the sensitivity is relatively constant). The element is preferably sensitive to infra-red.
