Definitions
- a projection process which comprises subjecting a silver halide image to a sulfiding treatment, treating the image thus treated with a solution containing a solvent for silver halide to provide a metal-glossy image, applying to the surface of the metal-glossy image an illuminating light beam for transmission and an illuminating light beam for reflection, combining the penetrating light beam and the reflected light beam, and projecting on a screen the combined light beam to provide a projected image having various contrasts.
- a process for making a metal-glossy image which comprises subjecting a silver halide image to a sulfiding treatment and then treating the image thus treated with a solution containing a solvent for silver halide.
- the present invention relates to a process for making a metal-glossy image from an image composed of silver halide. It also relates to an image projection process which comprises providing illuminating light for-transmission and illuminating light for reflection to the metal-glossy image while varying the light intensity ratio, combining the transmitted light and the reflected light and projecting the combined light on a screen to obtain projected images varying in contrast from the nunal image.
- a metal-glossy photographic image can readily be made having a high reflectance at an image area of high transmission density so that the contrast of the image may be varied easily by means of a contrast variable printing apparatus, an automatic printing of a printing paper, printing of a movie film, etc., many advantages are thereby obtained.
- the reason is that, in an automatic printing machine using a roll paper, it is impossible to exchange a printing paper for another according to the contrast of an image. Accordingly, the quality of an image obtained by an automatic printing machine will be markedly improved if the contrast of an image could be freely varied by an optical system of a printing machine. The same is true in printing of a positive film for cinema.
- the process consists in subjecting an image composed of silver halide to a sulfiding treatment and treating with a developing solution containing a solvent for the silver halide, and the latter image projection process consists in giving illuminating light for transmission and for reflection to the surface of the metal-glossy image obtained by the former process while varying the light quantity ratio, synthesizing the transmitted light and reflected light and projecting on a screen to obtain projected images varying in contrast.
- a photographic image having an optional contrast can be made by printing an image obtained by the image projection process of the invention on a suitable light-sensitive material.
- the metal-glossy image of the invention has a higher reflectance as a mirror surface at a high transmission density area than at a low transmission density area, and can readily be made.
- the metal-glossy image of the invention not only can the contrast of an image be varied within a certain range by the foregoing optical system, but also, if reflection illumination is given to an image, such as forming a negative image through transmission illumination, a positive image is obtained. That is to say, the positive-positive photographic process can be carried out according to the invention as in the case of subjecting a photographic lightsensitive material to reversal developing, since a negative image is projected, printed or viewed as a positive image, and vice-versa. Moreover, the metal-glossy image of the invention is available for the reversal viewer, projection of a slide or movie, etc.
- the image having a metallic gloss according to the invention is obtained, treating an image composed of silver halide with a solution containing a sulfiding compound to form fine particles of silver sulfide having a size of from 0.001 to 0.1 micron in said silver halide image and then developing with a developing solution containing a solvent for silver halide and a silver salt.
- a developing solution containing a solvent for silver halide and a silver salt may be used in place of the developing solution containing a silver salt.
- image 1 is projected on light-sensitive material for printing or screen 3 through projection lens 2
- image 1 is subjected to transmission illumination by means of light source 4 for transmision illumination and condenser lens 5 for transmission illumination, while being subjected to reflection illumination by means of light source 6 for reflection illumination, condenser lens system 7 for reflection illumination and half silevered mirror 8 (or partially reflecting and partially transmitting mirror).
- Both of the illuminating systems are so designed that the illumination intensity ratio may be varied, for example, by inserting light quantity modulators 9, 10 in the illuminating systems respectively or by making the intensity of the light sources variable.
- the light modulator is so composed that two optical wedges are moved in the reverse direction to each other or two sheets of polarizers are so arranged, the mutual azimuth of which is variable.
- incandescent lamps are used as light sources 4, 6 and the voltages are varied to control the quantity of light, the colors of the penetrating illumination and reflecting illumination become different. If it is necessary to balance the color in such a case, a monochromatic filter is preferably used for the projection optical system.
- E is the intensity of illumination of a transmission illumination of a reflection illumination light on the same illumination of areflection illumination light on the some image
- T is the transmittance of the image to an incident ray
- R is the reflection factor
- B C(E T+E R) where C is a constant determined by F-number of a projection lens, constants of the optical elements and their arrangement.
- E 0, that is, utilizing only a penetrating light
- B is proportional to T, for example, an ordinarily developed negative gives a negative image.
- E 0, that is, utilizing only a reflecting light
- B is proportional to R, for example, an ordinarily developed negative gives a reversed, positive image.
- gamma As a value representative of the contrast and as a value representative of the ratio of E and E the change of gamma with K is as shown in the following table, for example withrespect to the image obtained by the procedure of the example.
- the gamma of negative character is plus and that of positive character is minus.
- a positive image having a desirable tone can readily be made from any of various photographic images having a metallic gloss and contrast of a wide range as a matter to be photographed by the use of a positive film or printing paper having one kind of contrast.
- Exposure A silver halide photographic sensitive material is exposed in a camera or printed with another photographic image.
- Solution I Water (50 C.)-600 ml.
- Solutions I and II are prepared separately, cooled at room temperature and Solution II is added to Solution I little by little, with stirring, so that the total volume is 1000 ml.
- Bleaching is carried out at 20 C. for three minutes using a bleaching solution of the following composition:
- Potassium bichromate-ZO g Hydrochloric acid (30% )-50 ml. Water to 1000 ml.
- -It is preferred to use a bleaching solution which forms silver chloride.
- Metal-glossy developing is carried out at 30 C. for four minutes using a developing solution of the following composition to obtain a metal-glossy image:
- Step 9 An image having a metallic gloss is obtained by the foregoing steps.
- Step 9 squeezing, may be replaced by immersion in a surfactant solution.
- the metallic gloss appears after the layer is dried.
- the surface area having maximum metallic gloss is illuminated at an angle of incidence of 45 and the reflected rays are measured in the normal direction of reflection having an angle of 45 in the plane of incidence against a line vertical to the surface.
- the measured value is 30 in this case, and 100 in the case of a vacuum vapor deposition surface of aluminum. The larger this value, the greater is the metallic gloss.
- the contrast of the image can be sufliciently varied or a reversal image can be formed by changing the ratio of intensities of the reflecting illumination and transmitting illumination, as shown in Table 1.
- the sulfiding treatment may be carried out by immersing a sensitive material in an aqueous solution of hydrogen sulfide as well as a dilute solution of an inorganic sulfide, such as sodium sulfide or ammonium sulfide and an aqueous solution of an organic compound including unstable sulfur atoms, such as, thiourea, its derivatives or thioacetarnide, in addition to the exposure to hydrogen sulfide gas as mentioned above.
- an inorganic sulfide such as sodium sulfide or ammonium sulfide
- an organic compound including unstable sulfur atoms such as, thiourea, its derivatives or thioacetarnide
- the solvent of silver halide to be added to a developing solution for glossing as in the example is selected from the class consisting of thiosulfate, sulfite and halogen salts besides the well known solvents, such as, thiocyanate, ammonium salts, organic bases, etc.
- Methods of making images composed of silver halide are classified roughly into the following three groups, in addition to the method of converting into a silver halide image by subjecting a silver image to bleaching, said silver image being obtained by developing and fixing a silver halide photographic light sensitive material after exposure:
- the first is a method of utilizing the so-called photoetching art. This comprises providing a layer of light sensitive polymer the properties of which change with light on a layer of silver halide coated onto a support, adhering thereto a photographic image formed on a film, exposing the assembly to a light existing in the sensitive Wavelength region of said polymer, treating to form an image of the light sensitive polymer according to said photographic image, treating 'with a solvent for silver halide to remove silver halide at an area where the polymer is removed, and then removing the polymer layer to retain a photographic image composed of silver halide.
- the second is an application of the printing method. That is, a printing plate of an image is made by the conventional method and printed on a support, such as, paper or film, by the use of a solution containing silver halide and having a suitable viscosity as Well as adhesiveness to the support in place of a printing ink, thereby to give an image composed of silver halide.
- a silver halide image may be made by carrying out printing on a layer of silver halide according to an image by the use of a solvent for silver halide in place of a printing ink and treating with water to remove silver halide partly.
- the third is a method of obtaining a silver halide image comprising writing an image directly on a support, such as, paper or film, in pen or brush by the use of a solution containing silver halide.
- a silver halide image may be obtained by writing an image directly on a light sensitive material of silver halide in pen or brush by the use of a solvent for silver halide in place of an ink to remove silver halide partly.
- the process of the invention is applicable to any of the images composed of silver halide made by the foregoing methods, resulting in an image having a metallic gloss in each case.
- the image is not necessarily suitable for projection with change of the contrast due to a high penetrating density and low reflecting density of said support, but finds uses for the publication of advertisements, displays, etc., being capable of forming a peculiar visual effect due to the metallic gloss.
- a process for making a metal-glossy image which comprises subjecting a silver halide image formed on a support to a sulfiding treatment and then treating the image thus treated with a solution containing a solvent for silver halide.

- said solvent for silver halide is an aqueous solution of a member selected from the group consisting of a thiosulfate, a sulfite, a halide, a thiocyanate, an ammonium salt, and an organic base.
- a projection process which comprises applying to the surface of an image-containing element an illuminating light beam, applying to the opposite surface of said imagecontaining element a second illuminating light beam, combining the light beam passing through the image-contain ing element and the light beam reflected from the imagecontaining element to form a combined light beam and projecting on a screen the combined light beam to provide a projected image having various contrasts
- the improvement which comprises using as the image-containing element the metal-glossy image prepared according to the 11.
- said silver halide image is formed by preparing an assembly comprising a support having a silver halide layer coated thereon, a light sensitive polymer layer coated on said silver halide layer, and a photographic image on said polymer layer, exposing said assembly to light of a wave length to which said polymer layer is sensitive, removing a portion of said polymer layer to form an image in the polymer layer corresponding to the photographic image, treating said assembly with a solvent for said silver halide to remove said silver halide from said silver halide element at the polymer removed areas, and removing said polymer layer.
- said silver halide image is formed by printing a silver halide image on a support using a solution of a silver halide.
