摘要:
Improved compounds and base precursors that undergo thermal decomposition are disclosed. Thermal base precursors, and in particular, a novel class of salts of arylsulfonylacetic acids as bleaching agents or promoting for photothermographic use are disclosed. Compositions employing these thermal base precursors are suitable for use in acutance and antihalation systems, bleachable filter dye materials, and in promoting unblocking of various components such as blocked developers, especially in photothermographic elements.
摘要:
A heat developing method for obtaining a visible image comprising contacting a heat-developable light-sensitive material or a light-sensitive heat-sensitive recording material on which a latent image has been formed with a heating means in a heat developing part, wherein the heat-developable light-sensitive material or light-sensitive heat-sensitive recording material which is peeled off from the heating means is cooled, in a noncontacting state, to a temperature not higher than a temperature at which progress of development is stopped, and then the material is held with a transfer means for discharging the material outside of the heat developing part, and a developing apparatus for obtaining a visible image.
摘要:
A silver halide light-sensitive material comprises a support, a hardening layer and a light-sensitive layer in order. The light-sensitive layer contains silver halide and a hydrophilic polymer. The hardening layer or the light-sensitive layer contains a reducing agent. The hardening layer contains a mixture of a polymer (A) and a polymer (B). The mixture contains the polymer (A) in an amount of 5 to 70 wt. % and the polymer (B) in an amount of 30 to 95 wt. %. The polymer (A) comprises repeating units of (A1) in an amount of not less than 95 mol %. The polymer (B) comprises repeating units of (B1) in an amount of 10 to 90 mol % and repeating units of (B2) in an amount of 10 to 90 mol %. ##STR1##
摘要:
A silver halide color photosensitive material comprises a support provided thereon with a photosensitive silver halide, a developing agent, a coupler, and a binder. After exposure, the photosensitive material is placed, onto a processing material comprising a support provided with a processing layer thereon which contains a base and/or a precursor of a base, with water being present between the photosensitive material and the processing material in an amount of 1/10through 1 times that required to maximally swell the layers of the materials. The resultant assembly is heated to form an image on the photosensitive material. The photosensitive material includes an emulsion in which tabular silver halide grains having an aspect ratio of 2 to 30 account for 50% to 100% of the total projected area of all silver halide grains and in which 50% to 100% of all silver halide grains in number include 10 or more dislocation lines per grain. A method of forming images using this photosensitive material is also disclosed.
