Definitions
- Light-sensitive diazotype materials susceptible to heat development as disclosed in the Greig Patent are subject to the disadvantage that the relatively high acidity of the sensitizing composition causes deterioration of the paper coated therewith, impairing the storage qualities or shelf life of the product.
- the acid stabilizers employed in accordance with the invention are those conventionally used in two-component diazotype materialsfor example citric acid, tartaric acid, acetic acid and the like. These are used together with conventional light-sensitive diazonium compounds, as for example those referred to in US. Patent 2,501,874 and in the article by Van der Grinten in Photographic Journal, volume 92B (1952) page 46.
- Preferred diazonium compounds are those derived from N-monoor N,N-disubstituted-p-phenylenediamine, as for example:
- Azocoupling components suitable for use in the sensitizing compositions of the invention are those commonly employed in two-component diazotype photoprinting materials, such as:
- the quantity of the trichloroacetic acid salt employed in'the sensitizing composition should be such as to exceed the stoichiometric equivalent of the quantity of base required to neutralize the acid stabilizer present in the mixture.
- a quantity of said salt from one to three times the stoichiometrical equivalent of the acid stabilizer is suitable.
- the quantity of said salt exceeds the sum of the stoichiometric equivalent of the diazonium compound and of the acid stabilizers.
- the proportions of the other components of the mixture are those conventionally used in diazotype sensitizing compositions.
- the sensitizing composition is advantageously applied in the form of an aqueous solution as a coating to a base, especially paper or cellulosic materials such as regenerated cellulose and allowed to dry.
- a base such as paper sensitized with a conventional twocomponent diazotype sensitizing composition can be treated e.g., by spraying or padding with an aqueous solution of the trichloroacetic acid salt, and then dried.
- the trichl-oroacetate may be concentrated in the surface stratum of the sensitized layer so that the excess is sufficient to effect development of the image in that portion of the layer, even though underlying strata of the sensitized layer may lack sufficient trichloroacetate to effect development.
- the material After exposure under an opaque pattern to actinic light the material can then be developed at temperatures ranging from about 100 C. to the scorching temperature of the paper. Temperatures from 120 C. to 200 C. are satisfactory.
- the trichloroacetic acid salt decomposes, rendering the salt-forming alkali metal or ammonium moiety thereof available to neutralize the acid stabilizer, and thereby causing coupling of the diazonium salt with the azo coupling component.
- Example I A sensitizing solution is prepared by combining the following ingredients: Water cc 60 Glycerin cc 5 Isopropyl alcohol cc 1 Citric acid g 5 Zinc chloride g 5 N-beta-hydroxyethyl-N'-allyl-thiourea g- 2.5 2,3-dihydroxynaphthalene-6-s-odium sulfonate g 4 4-N,N-diethylaminobenzene diazonium chloride-zinc chloride double salt g 2 Saponin g 0.1 Sodium trichloroacetate g 12 Finely divided silica (1-5 microns) g 6 Water to make cc 100 This solution is coated on high grade sulfite bond paper, and dried. After exposure of the sensitized material to actinic light under an opaque pattern on a translucent supporting sheet, the sensitized material is heated to a temperature of about 120 C. An azo dye image is rapidly formed, reproducing the pattern of the original.
- Example II Sulfite bond paper is coated with a sensitizing solution having the following composition:
- Example III A paper base coated with a sensitizing solution having the following composition:
- Example IV Paper preooated with an aqueous suspension of colloidal silica and then dried, as sensitized by coating with a sensitizing composition having the following ingredients:
- the resulting material is dried and exposed under a pattern to actinic light. On heating to 130 C. an image is rapidly formed, reproducing the pattern.
- the other ingredients of said compositions can be combined and applied to a supporting sheet and dried, yielding a two-component diazotype sensitized sheet of the kind heretofore used for ammonia development.
- An aqueous solution of alkali metal or ammonium trichloroacetate having, for example, a concentration of 1020%, can then be applied to the sensitized surface of the sheet by atomizing, padding or the like, and the sheet again dried.
- the surface portion of the lightsensitive layer includes the trichloroacetate salt in a quantity exceeding the stoichiometric equivalent of base required to neutralize the acid stabilizer in the same portion of the layer, even though the total quantity of acid stabilizer contained in the surface layer and underlying layer may exceed the stoichiometric equivalent to the trichloroacetate.
- the material thus sensitized can be developed after exposure to actinic light under an opaque pattern, by heating to a temperature above 100 C., causing decomposition of the trichloroacetate with generation of sufiicient alkaline reacting residue to cause imagewise coupling of the two-component diazotype composition in the surface portions of the light-sensitive layer.
- neutral salts of other bases which are themselves otherwise unreactive or inert toward the ingredients of the sensitizing composition can be used, e.g., the other alkali metal salts, alkaline earth metal salts and nitrogen base salts, trichloroacetates of mono-, diand tri-ethanolamine, or of triethylenetetramine, benzylamine or trimethylamine.
- a sensitizing composition for diazotype photoprinting material comprising, in aqueous medium, an azo coupling component, a light-sensitive diazonium salt, an acid stabilizer against coupling, all such stabilizers of the composition having a dissociation constant at 25 C.
- a neutral saltof trichloroacetic acid selected from the class consisting of sodium, potassium and ammonium salts, in an amount exceeding the stoichiometric equivalent of the amount of base required to neutralize said acid stabilizer.
- Light-sensitive diazotype photoprinting material comprising a supporting sheet having thereon a light-sensitive surface layer comprising an azo coupling component, a light-sensitive diazonium salt, an acid stabilizer against coupling, all such stabilizers of said layer having a dissociation constant at 25 C. within the range of 10 to the 10 and a neutral trichloroacetic acid salt of the class consisting of sodium, potassium and ammonium salts, the amount of said salt in at least the surface portion of said layer exceeding the 'stoichiometric equivalent of the (3 amount of base required to neutralize the acid stabilizer in said surface portion of said layer.
- Light-sensitive diazotype photoprinting material as defined in claim 6, wherein said light-sensitive diazonium salt is a zinc chloride double salt derived from a diazotized N-substituted p-phenylenediamine.
