摘要:
Holograms using gelatin as the binder are prepared by holographically exposing holographic material with coherent light, developing the holographic image by a chemical or physical process and before processing, simultaneously or subsequently, treating the material with an aqueous solution of a polymer which comprises a tertiary amine group.
摘要:
Holograms which contain gelatin as the binder are prepared by holographically exposing the material by use of coherent light, developing the holographic image by a chemical or physical process and before processing, simultaneously or subsequently, treating the material with a solution of a gelatin reactive compound which has a molecular weight of over 200 and which reacts with the gelatin to form covalent bonds therewith to increase the molecular bulk of the gelatin.
摘要:
A blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 mu m, and comprise at least 90 mol % bromide and from the0.5 to the2.75 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer. In addition, the tabular grain emulsion includes a mercapto-substituted benzothiazole, benzoxazole, or benzimidazole to provide desired image tone and processability.

A development processing apparatus for a silver halide color paper, comprising: a first processing tank for processing a light-sensitive material with a color developer; a second processing tank for successively processing the light-sensitive material with a bleaching solution; a third processing tank for successively processing the light-sensitive material with a solution having a fixing ability; and a passage between the second processing tank and the third processing tank, wherein the passage is sealed while the passage allows to pass the light-sensitive material, and the light-sensitive material is conveyed in a solution without contacting air through the passage. And a method for processing a silver halide color paper, wherein the light-sensitive material is conveyed in a solution without contacting air, and wherein a sum of a processing time is 12 seconds or shorter.
摘要:
A radiographic silver halide film useful for mammography comprises a support having a cubic grain silver halide emulsion on one side. The cubic grains are spectrally sensitized with a combination of first and second spectral sensitizing dyes that provides a combined maximum J-aggregate absorption of from 540 to 560 nm. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine and the second spectral sensitizing dye is an anionic oxycarbocyanine. The first and second spectral sensitizing dyes are present in a molar ratio of from 0.25:1 to 4:1.
