Definitions

  • An image-receiving element for use in silver halide diffusion transfer processes which element comprises a support having coated thereon a diffusion transfer image-receiving layer comprising a colloidal silicon dioxide containing silver-precipitating nuclei dispersed therein, said image receiving layer being overcoated with a layer containing therein poly-addition products derived from a bisacrylamide and a diamine compound, which bisacrylamide is represented by the following general formula wherein R is a divalent hydrocarbon group having not more than 10 carbon atoms.
  • the overcoating layer serves as a stripping layer of improved properties.
  • light-sensitive photographic materials comprising a support having coated thereon a dispersion of fine particles .of a light-sensitive silver salt, such as a silver halide in a hydrophilic binder such as gelatin.
  • a light-sensitive silver salt such as a silver halide in a hydrophilic binder such as gelatin.
  • the light-sensitive layer thereof was exposed to light image-wisely and then contacted with a processing composition containing therein a developing agent to affect development of the exposed layer. At this point, the exposed silver halide in the lightsensitive layer is reduced (developed) to metallic silver.
  • the light-sensitive element is processed with a silvercomplex forming agent, whereby a water-soluble silver complex is formed by reaction of the unexposed silver halide with the silver-complex forming agent.
  • a silvercomplex forming agent which substance serves as a catalyst for reduction of the abovedescribed water-soluble silver complex (said substance therefore comprising silver-precipitating nuclei or development nuclei)
  • an image-receiving element having an image receiving layer containing therein a substance dispersed in a hydrophilic binder, which substance serves as a catalyst for reduction of the abovedescribed water-soluble silver complex (said substance therefore comprising silver-precipitating nuclei or development nuclei)

It is then reduced to silver by the effect of the development nuclei contained therein, thereby forming a positive image having a pattern corresponding to the original.
  • the imagereceiving element In order to obtain the desired print, the imagereceiving element must be dissociated or stripped from the light-sensitive element.

  • the dissociation or stripping is unsatisfactory and/or the processing composition re mains thereon, the image-surface of the imagereceiving element is tainted and the quality of the image is remarkably lowered.
  • the silver images formed on the imagereceiving element frequently undergo deterioration upon storage and/or the highlight areas thereof yellow.
  • the above-mentioned materials are effective to stop processing composition remaining on the surface of the positive print, and to protect the surface of the image-receiving sheet from. being scratched during handling, they often present disadvantages in that the transferred image assumes a metallic luster and/or the maximum density of the positive image is lowered.
