Definitions

  • An image-receiving material according to the invention may, e.g., consist of a support which is impregnated with development nuclei or a substance or substances for forming such nuclei in situ. As an alternative such nuclei or nuclei-forming substances may be incorporated in an image-receiving layer applied onto such support.
  • An image-receiving material according to the invention preferably comprises a non-light-sensitive colloid layer, e.g.,
  • Example 4 A light-sensitive material for the silver complex diffusion transfer process is prepared by coating onto a paper support a gelatino silverchloro-iodide emulsion (0.5% of iodide). i1 kg. of flowable emulsion has been prepared starting from 45 g. of silver nitrate. The emulsion is sensitized for light of 500 to 570 m wavelength and is cast in such a Way that the silver content amounts to 1.5 g./sq. m. of paper.
