Definitions

  • This invention relates to an improved material for being applied in the silver complexdiifusion transfer process and to a process wherein this material is used.
  • the rapidity of the deposition of the silver and consequently the density of the diffusion transfer image depend to a high degree on the nature and concentration of the developing nuclei used.
  • Any water-permeable layer which enables the diffusing complexed silver halide to penetrate into the image-receiving material and which makes it possible'to obtain a good separation between the image-receiving material and the light-sensitive material after the formation of the diffusion transfer image, can be used as water-permeable covering layer.
  • Suitable covering layers are among others described in the French patent specifications 1,304,279 and 1,304,280.
  • Colloidal silica used in the material and the process according to the present invention is, e.g., Santocel C (tradename of Monsanto Chemical Company, St. Louis, Mo., USA.) and dispersions of hydrated silica are, e.g., Ludox LS (tradename of E. I. du Pont de Nemours &'Co. (Inc) Wilmington, Del, U.S.A., for a 30% aqueous dispersion of silica) and Syton 2X (tradename of Monsanto Chemical Company, St.
  • silica compositions can be dispersed in the coating composition of the water-permeable layer in an amount mostly varying from 5 to 50 g. per liter. More details about the thickness of a water-permeable covering layer are United States Patent 0 given in the patent specifications dealing with such covering layers, among others the two above mentioned French patent specifications.
  • the image-receiving material may consist of a support or of a support'carrying a water-permeable colloid layer which contains developing nuclei for complexed silver halide. Physical as well as chemical developing nuclei are suited.
  • Developing nuclei suitable for promoting the formation of the silver-containing image in the image-receiving layer are the sulfides of heavy metals, e.g., antimony, bismuth, cadmium, cobalt, nickel, iron, tin, thallium, copper, lead, silver and zinc.
  • the selenides, polysulfides, polyselenides, mercaptans, stannous halides, heavy metals or their salts and fogged silver halide are also suited for this purpose.
  • the complex salts oflead sulfide and zinc sulfide either in themselves or mixed with thioacetamide, dithiobiuret or dithio-oxamide are especially effective.
  • the heavy metals silver, gold, platinum, paladium and mercury are particularly worthy of mention, especially in their colloidal form. The noble metals among them are the most active.
  • These developing nuclei for silver can be incorporated in the support material itself or they can be applied onto a suitable support such as paper, from solutions or dispersions of such developing nuclei in a colloid medium such as gelatin.
  • the image-receiving layer and/or the hydrophilic covering layer can still contain all kinds of other ingredients such as'developing substances, complexing agents for silver halide, optical bleaching agents, softening agents, black-toning agents etc.
  • Suitable black-toning agents are described in the Belgian patent specification 605,802, the French patent specifications 1,305,068 and 1,140,526 and the United States patent specification 2,699,393.
  • any silver halide emulsion is suited for being used in combination with the image-receiving material according to this invention.
  • Silver chloride emulsions which'may also contain silver bromide or silver iodide or to which some ingredients may be added so as to impart the desired emulsion characteristics are preferably used.
  • Some materials playing a part in the diffusion transfer image formation may also be incorporated in the light-sensitive material.
  • the composition of the developing liquid is the one usually used in the silver complex diffusion transfer proc- I ess: it contains among others the ingredients necessary for the development of the exposed silver halide such as hydroquinone and 1-phenyl-3-pyrazolidone, a complcxing agent for silver halide etc. Some of these ingredients can be wholly or partially incorporated in the light-sensitive or image-receiving material.
  • Example I A receiving layer is coated onto a paper support of 90 g./ sq. m. from a suspension of the following composition:
  • the obtained image-receiving material is dried and together with an image-wise exposed silver chloride emulsion material containing 1.3 ig. of silver chloride per sq. m. passed through a developing bath of the following composition:
  • image-receiving material and the light-sensitive material are separated.
  • Example 2 A receiving layer is coated onto a paper support of 90 g./ sq. m. from a suspension of the following composition:
  • a photographic image-receiving material for forming prints thereon according to the silver complex diffusion transfer process by precipitating the silver of image-wise distributed soluble silver complexes of an exposed photosensitive element including a support and a silver halide emulsion layer, brought into contact therewith, said material comprising a support, a water-permeable imagereceiving layer containing development nuclei and a hydrophilic, water-permeable surface layer on said image receiving layer, said surf-ace layer containing colloidal silica and being free of silver precipitating agent.
  • a process of forming transfer images comprising the steps of exposing a light-sensitive material comprising a support and a silver halide emulsion layer, contacting said exposed material With an image-receiving material comprising a support, a water-permeable image-receiving layer containing development nuclei and a hydrophilic Waterperrneable surface layer on said image-receiving layer, said surface layer containing colloidal silica and being free of silver precipitating agent, separating the lightsensitive material from the image-receiving material containing the transfer image, the transfer being effected in the presence of a developing substance and a solvent for silver halide.
