Definitions

  • This invention relates to new and useful permanent reproductions and their method of preparation by selectively depositing a basic nitrogen containing compound on the surface of a photoconductor.
  • An object of this invention is to disclose a method of selectively depositing basic nitrogen containing organic compounds on the surface of a photoconductor thereby producing reproductions in a fast and eicient manner.
  • Another object of this invention is to disclose a process for preparing colored reproductions by electrophotography.
  • Full colored reproductions are prepared by successively applying subtractive primary colors to the surface of the dye-sensitized photoconductor.
  • the method of making colored reproductions from subtractive primaries is described in I. S. Friedmans A History of Color Photography, American Photographic Publishing Company, Boston, Mass. (1944).
  • the tem-n dye-sensitized indicates that the photoconductor has been treated with an organic dyestuff so that radiant energy is absorbed by the dye on the surface of the photoconductor and the energy is transferred to the photoconductor thereby making the photoconductor conductive.
  • This process may be employed in various ways to prepare permanent photographic reproductions.
  • the preferred method of course is to directly deposit a basic nitrogen containing organic dyestuff directly on the photoconductor. If the basic nitrogen containing organic compound is colorless it may then be dyed or colored in a 3,418,322 Patented Dec. 24, 1968 ice subsequent step to produce a negative image, or the deposited compound may serve as a protective coating on the surface of the photoconductor and the unprotected areas dyed or modified chemically in some manner, such as by etching away the photoconductor with an acid or sol-vent. Likewise the compound deposited on the surface of the photoconductor may sufficiently modify the wetting characteristics of the photoconductive sheet. In this manner the two areas will have a differential repellency or attraction to water or oil.
  • the varying of the surface wetting characteristics of the photoconductive sheet is particularly suitable for the production of lithographie plates where the photoconductor is rendered hydrophobic by the deposited compound.
  • the structural formula of the basic nitrogen containing organic compound to be deposited from an aqueous solution in accordance with the teachings of this invention corresponds to the formula.
  • M is an organic radical
  • R and R are hydrogen or an alkyl radical containing up to 18 carbon atoms
  • m is an integer of less than 4
  • p is an integer of less than 6
  • n is an integer of less than 6.
  • a preferred class of compounds are those that contain an alkyl radical of at least 6 carbon atoms (preferably 10)
  • R is an alkyl radical of at least 6 carbon atoms (preferably l0)
  • the R radicals are alkyl radicals containing less than 6 carbon atoms.
  • the long chain alkyl radical may also be present in the radical M, as in the case of the amino-polyamides described but is preferably one or more of the R constituents.
  • the preferred class of dyestuffs falling within the above general formula is where M is an organic radical containing a chromogenic nucleus. Illustrative chromogenic nuclei are represented by the following general classes of dyestuffs:
  • colorless images may be prepared or the colorless basic nitrogen containing organic compound may be deposited in the presence of colloidal organic 'or inorganic pigments.
  • a reaction product of dimerized linoleic acid and an excess of a polyethylenamine having an amine number of about is dissolved in ethanol and acetic lacid as a one percent solution.
  • This solution may then be neutralized ⁇ at the photoconductor-cathode and thereby a colorless insoluble solid is deposited on the surface of the photoconductor.
  • the solution is mixed with colloidal titanium dioxide, neutralization and deposition of this dispersion results in the production of white images.
  • the photoconductor-cathode is some color other than white, the titanium dioxide may be deposited yas the white portions of an image. In this manner, a direct positive image is formed.
  • ⁇ Carbon black images may be formed by mixing colloidal carbon in the solution. Using this type of dispersion black images are prepared which are completely resistant to the action of light and most atmospheric conditions. As such, they represent one of the most permanent photographic elements attainable.
  • These basic nitrogen containing organic compounds are dissolved in water by the formation of a salt with an acid moiety.
  • Suitable organic acids include formic acid, acetic acid, lactic acid, levulinic acid and the like.
  • Suitable inorganic -acids include hydrochloric acid, nitric acid7 sulfurie acid and the like.
  • the final pH of these solutions is in the range of pH 2 to 7 (preferably 4.5 to 7).
  • These aqueous solutions which are substantially free 'of positive ions other than those containing the basic nitrogen-containing organic compound are employed at solution concentrations of 0.1 to by weight.

  • Developer tray 10 is composed of a base plate 12, which also serves as an electrode, top clamping frame member 14, and an intermediate yopen frame member 16 ttorrning upstanding walls around the base plate periphery.
  • Frame member 14 and base plate 12 have cooperating, releasable clamping means 18, which draw these members toward one another when engaged to render the tray 10 water tight.
  • the open frame member 16 is composed of a nonconductor such as polyethylene, polytetrauoroethylene or polytrifluorochloroethylene and is provided with a ledge 20 for supporting electrode 22 such that an electrical current passing to electrode 22 from the base plate-electrode 12 passes through ya photoconductor sheet 24 which is interposed between the open frame member 16 and the base plate 12.

  • FIGURE 2 In order to graphically show the photoconductor particles 28 and the image deposit 30, they have been represented in FIGURE 2 in exaggerated size.
  • a stepwise procedure for producing an image in accordance with the -teachings of this invention is as follows:
  • the negative electrode from a direct current power supply 34 is attached to the metal base plate thereby making electrical conta-ct with the conductive backing of the photoconductor sheet 24.
  • the photoconductor sheet 24 in the developing tray 10 is exposed to light in selected areas such as by focusing and projecting a photographic negative on the photoconductor sheet 24 through a light projector.
  • the electrode 22 is placed on the ledge 20 and connected to the positive terminal ofthe direct current power supply 34.
  • the solution 32 is added to the tray.
  • the electrical current is turned on so as to elect the electrolytic development.
  • the solution is poured off and the photoconductor sheet is thoroughly washed with water. Aditer suitable dark adaptation additional images may be put on the photoconductor sheet by repeating the above procedure.
  • An especially useful method for dark adaptation of the photoconductor sheet is to place it in contact with water heated to at least 100 F. which may be accomplished simultaneously with the washing by employing the hot Water as the wash water.
  • Full color reproductions may be obtained by carrying out the above procedure three times with monochromatic light.
  • a color negative is placed in a projector equipped with a photoflood lamp and a red lter is interposed between the photoflood lamp and the photoconductor sheet, preferably between the color negative and the phototlood lamp, thereby exposing the photoconductor sheet selectively to red light.
  • a cyan image is then developed on the photoconductor using a cyan dye.
  • the photoconductive paper is then washed with warm water (heated to at least F.) and dried with a stream of air.
  • the developing tray is then returned to the enlarger and a green lter is interposed between the light source and the photoconductor sheet.
  • the light intensity of the projected image, time of exposure which may be from 0.1 second to sixty seconds, and period of electrolytic development which may be from 1 to 30 seconds at a voltage of from 5 to 150 volts are varied in accordance with quality of the image required or desired and the relative effectiveness of the photoconductor surface.
