Definitions

  • the present invention relates to the manufacture of photographic diazotype materials having particular utility in the preparation of intermediate or transition prints and more particularly to the base of such diazotype materials to which the sensitizing composition is applied.
  • the diazotype process which is of rather general application in the formation of prints from original patterns, has become increasingly more importantin the preparation of transition prints or intermediate prints on a transparent base stock for the purpose of reproducing drawings, or ginals of old manuscripts and the like.
  • the efiiciency of these prints depends upon a number of factors, to wit, the opacity of the azo dye image formed to ultraviolet light, the transparency of the background, the speed at which the intermediate print may be reproduced, and the like.
  • diazotype materials which yield valuable transition or intermediate prints.
  • These diazotype materials are prepared with a transparent support such as transparentized paper, i. e., rag paper, cellulose esters such as cellulose acetate, and the like.
  • transparentized paper i. e., rag paper
  • cellulose esters such as cellulose acetate, and the like.
  • diazotype materials do not represent the ultimate from a practical standpoint, particularly as regards contrast, line density, speed of duplication and the like.
  • a further object of the present invention is to produce photographic diazotype materials having a glassine paper base, said materials having the ability to permit duplication at a much greater rate than any materials of a like nature presently known.
  • the glassine paper which is to serve as the base is commercially available and may be prepared according to, for example, U. S. P. 1,914,798 and 1,914,799. While different weights of paper may be used for the preparation of the lightsensitivematerials, I have discovered that best results are obtained when utilizing a 25-pound weight paper (500 sheets, 24 by 36 inches).
  • Glassine paper in and of itself is not particularly strong. It is therefore preferable to incorporate in the coating composition an organic film forming material to thereby increase the strength of the base.
  • Any organic film forming material either water-insoluble or Water-soluble may be employed, so long as it is transparent in a thin layer such as a layer having a thickness of .01 inch or less. Film forming materials which meet this requirement are known and are available on the open market.
  • suitable water-insolublefilm forming materials are: polystyrene, polyacrylic acid esters such as the methyl or ethyl ester, polymethacrylic acid ester such as the methyl or ethyl ester, the copolymers of vinyl chloride and a vinyl ester such as vinyl acetate, copolymers of maleic anhydride and styrene, copolymers of vinylidine chloride and vinyl acetate, alkyd resins such as those derived from phthalic acid and glycerol, phthalic acid and sorbitol, phthalic acid, glycerol and a drying oil, such as poppyseed oil, cellulose esters such as cellulose acetate, cellulose acetate-butyrate, cellulose propionate, cellulose acetate-propionate, linear superpolymers such as linear superpolyamides, linear superpolyurethanes, linear superpolyureas and the like.
  • organic film forming materials such as organic
  • the sensitizing composition containing'such material is applied from a solution of the ingredients in an organic solvent.
  • resin solvents such as acetone, butyl acetate, benzyl alcohol, butyl alcohol, mixtures of ethers and alcohols such as a mixture of ethanol and ethyl ether, chlorinated hydrocarbons such as chloroform, ethylene chloride, and mixtures of such chlorinated hydrocarbons with alcohols or ethers such as ethylene chloride and butyl chloride and diethyl ether and the like.
  • the light-sensitive diazonium compounds employed in the sensitizing composition are those generally utilized in the manufacture of diazotype papers but are preferably of the class of the paraphenylene diamines.
  • Such coupling components are the phenols, particularly the polyhydric phenols and their derivatives, such as resorcinol, resorcinol monoand disulfonic acids, phenol itself, 2- (omega-phenylamino) -methyl-l-hydroxybenzene, p (2 hydroxyphenyD-propionic acid, and similar compounds referred to in U. S. P. 2,245,628, 2.7-dihydroxynaphthalene (U. S. P. 1,758,676) phloroglucinol and the like.
  • Such coupling components will hereinafter be referred to as phenolic coupling components capable of yielding with the usual diazos, azo dyestuff images having a yellow or sepia tone.
  • the sensitizing compositions may contain the usual adjuncts such as metal salts, to intensify the dyestuif image, i. e., aluminum sulfate, titanium ammonium fluoride, nickel sulfate and the like, stabilizing agents such as thiourea, thiosinamine, naphthalene trisulfonic acid and the like, acids designed to retard precoupling such as citric acid, maleic acid, tartaric acid, boric acid and the like, hygroscopic agents such as glycol, glycerin, dextrin and the like.
  • adjuncts such as metal salts, to intensify the dyestuif image, i. e., aluminum sulfate, titanium ammonium fluoride, nickel sulfate and the like
  • stabilizing agents such as thiourea, thiosinamine, naphthalene trisulfonic acid and the like
  • acids designed to retard precoupling such as citric acid, maleic
  • the sensitizing compositions In making up the sensitizing compositions, one uses the amounts of diazo compound, coupling component and the other usual adjuncts customary in the art. If desired, however, one may also employ a slight excess of the diazo and coupling component although as ageneral rule this is unnecessary.
  • the quantity of the resin which is to be employed will vary from about 5 to 20 per cent by weight of the composition and is preferably about 10 per cent.
  • the quantity of the sensitizing composition which is applied to the base ranges from about 10 to 12 per cent by weight of the base.
  • Example 1 25-pound glassine paper is coated in an apparatus of the type shown in the drawing on both faces with a sensitizing composition having the following ingredients:
  • Example II Glassine paper prepared according to USP 1,914,798 or 1,914,799 is simultaneously coated on both faces with a composition prepared as follows:
  • photographic diazotype glassine papers referred to hereinabove have been described as particularly suitable for the preparation of transition or intermediate prints. It is to be pointed out, however, that such photographic diazotype papers have many other applications such as, for example, overlays used for multicolored prints, especially semi-transparent Wrappers, lamp-shades and the like. When so utilized, it is unnecessary to select coupling components which yield yellow or sepia toned azo dyes inasmuch as the question of ultraviolet light opacity is not of particular moment in these applications.
  • dihgdroxynaphthalene dihgdroxynaphthalene. It is therefore to be understood that the invention in its broadest aspects contemplates photographic diazotype materials in which a sensitizing composition comprising a diaio component and an azo dyecoupling component are applied to a glassine paper base.
  • Transparent diazotype materials particular- 1y suitable for the preparation of intermediate or transition prints comprising a glassine paper base having applied to both faces thereof a sensitiz ing composition comprising a light-sensitive diazo compound, a small quantity of a resinous low viscosity cellulose ester film forming material and a phenolic coupling component capable of yielding with the diazo compound anazo dye having atone selected from the class consisting of yellojw and sepia tones.
  • Transparent diazotype materials particularly suitable for the production of transition and intermediate prints comprising a glassine paper base having applied to both surfaces thereof a sensitizing composition comprising a low viscosity cellulose acetate, p-diethylaminobenzene diazonium borofluoride and resorcinol.
