  • the image when a microencapsulated black-and-white emulsion or color emulsion is applied to a lustrous surface of an aluminum plate, the image, obtained on exposing and developing, is unexpectedly bright. Furthermore, this image has the appearance of a transparent positive and the feeling of printing'paper. This effect is remarkably evident, specifically in this color areas or highly lighted areas, giving the image a number of bright points in the depth of a uniform color as if a metal powder coated surface or metallic coating were being viewed.
  • the aluminum surface used as the support reflects light well
  • the particles on the surface of the aluminum plate consist mainly of gelatin and light passes through it well and is scattered;
  • the green-sensitive capsules and blue-sensitive capsules form colors, such as magenta and yellow, respectively, forming the red image.
  • the red-sensitive microcapsules which are unexposed and thus uncolored, exist as transparent particles. Light passing through these particles causes the bright points. Y p.
  • the 'I'he photographic material of the invention has another advantage in that the surface is naturally matted because the microcapsules are exposed as particles. As a result, the visual stimulus is different than that obtained with prior art images.
  • the microcapsule-type emulsion used in making a photographic light-sensitive material for color printing by mixing the three color capsules, can be coated all at once. Accordingly, a thick metal plate can readily be coated as a support, as well as aluminum foil and iilms of vacuum-deposited aluminum.

  • a gelatino silver iodobromide emulsion 100 g.
  • 4% silver halide based on silver nitrate
  • 12% gelatin was added to a solution of 30 ml. of a 4% naphthalenesulfonic acid-formalin condensate in 840 m1. of water, held at 40 C. and then mixed with agitation with 39 ⁇ ml. of a 1% aqueous solution of acetic acid to lower the pH to 4.5.
  • a complex coacervate of gelatin and the foregoing condensate surrounded the silver halide crystal forming a spherical microcapsule of about 5 microns.
  • This product was then poured into a second vessel containing 3 liters of ice water and 0.6 g. of chrome alum, and the pH was raised to 6 by adding sodium carbonate. After stirring the mixture for l hour, the mixture was allowed to stand at room temperature. The following day, the supernatant liquid was removed and a hardened c psule slurry was obtained by centrifugal separation. 100 g. of 110% gelatin was added to the slurry as a binder to obtain a black and white microcapsule-type emulsion.
  • the black-and-white microcapsule-type emulsion'prepared as above was applied to an aluminum sheet, 210 microns thick and having a mirror surface at a level of 500 g./m.2. The material was allowed to set and then dried.
  • EXAMPLE 2 Photographic light-sensitive material containing a microcapsule-type emulsion for color photography
  • Microcapsules conventionally used in color photography i.e., microcapsules containing a blue-sensitive silver halide and a yellow coupler, microcapsules containing a green-sensitive silver halide and a magenta coupler and microcapsules containing a red-sensitive silver halide and a cyan coupler, were prepared according to the method described in Japanese patent publication No. 12948/ 1965.
