Definitions

  • a light source examples include a tungsten lamp, a halogen lamp, a xenon lamp, a mercury lamp, a laser, a CRT light source, an LED and an FOT, and these light sources are used singly or in combination.
  • STB-1 illustrated below was added as an emulsion stabilizer to each silver halide emulsion at a rate of 2 x 10 ⁇ 4 mol per mol silver halide.
  • Signal R for controlling a cyan dye image is input into a laser light modulation circuit 27.
  • Laser light 34 that is emitted from a He-Ne (wavelength 633 nm) laser 1 based on an output signal 31 is converged by a lens array 5, and then the converged light is reflected to a polygon mirror 19 by a dichroic mirror 6.
  • a laser beam scanned by the polygon mirror 19 is subjected to f ⁇ conversion by an f- ⁇ lens 20 and is focused onto a photosensitive material 23 via a mirror 21 and a cylindrical lens 22.
  • a photosensitive material is exposed with a beam of which intensity is modulated correspondingly to signals R, G and B.
  • Ferric ammonium ethylenediaminetetraacetate dihydrate 60 g Ethylenediaminetetraacetic acid 3 g Ammonium thiosulfate (70% aqueous solution) 100 ml Ammonium sulfite (40% aqueous solution) 27.5 ml
  • An ID image shown in FIG. 1 was formed by the above-mentioned treatment.
  • the photosensitive material was subjected to imagewise exposing in the same manner as in Example 1.
  • An intensity of the most intensive light used for exposing an area that is subjected to reading with IR light was more than 20 times more intensive than that of light used for exposing a color image area of each color.
  • an ID card comprising an image legible with IR light and a visible color image, both of which were formed by a single process.
