Definitions
- the porous layer is impregnated with a solution of a substance that is already photo-sensitive, for example a ferric salt, and, by the other process, the photosensitive substance, for example a silver halide, is produced by double decomposition in the film itself.
- a substance that is already photo-sensitive for example a ferric salt
- the photosensitive substance for example a silver halide
- Double chemical decomposition by-means of pre cipitation reactions for example with silver nitrate and potassium bromide, has very considerable disadvantages.
- suflicient silver halide it is necessary to repeat the precipitation reaction a number of times.
- a photographic reproduction surface is produced in an adsorbent, firmly adhering aluminum oxide layer by treating the layer with an organic substance which reduces silver compounds to metallic silver, treating the layer with a solution containing a silver compound,thereby to mordant metallic silver .to this layer and, finally, converting the metallic silver into silver halide.
- dyestufis having the character of mordants i. e., dyestuffs which have a certain chemical affinity to aluminum oxide, for example derivatives of anthraquinone (alizarin types), of flavone and xanthone, or derivatives of pyronin (gallein type) and .oxazine (gallocyanin type).
- organic compounds will reduce silver ions to metallic silver when, at least, two hydroxy or amino groups are in the ortho .or para position to each other in the ring system or-when a reactive aldehyde group is contained in the molecule.
- Suitable soluble oxalates are those of alkali metals and also those of metals of the titanium group, i. e., titanium, zirconium and thorium. With the former oxalates, clear, colourless, transparent layers are obtained, whilst with the latter oxalates non-transparent, opaque layers are obtained. The advantages of the employment of these layers for the purposes of the present invention are considerable. In addition to a good hardness and resistance to abrasion, they possess a high chemical resistance; they are very porous and absorbent and can very easily be dyed. On closing the pores by means of the usual warm, aqueous solutions, their surface becomes glass-hard and unsoilable.
- the reaction of the organic substance, deposited in the layer, with solutions containing silver in the form of ions is advantageously carried out by immersing the suitably pretreated article in the reactive silver solution; the latter may have a slightly acid, a neutral or a slightly alkaline reaction according to the reactivity of the organic substance.
- Ammoniacal silver solutions preferably those having no or only a slight content of ammonia, have been found to be advantageous and usable in most cases.
- temperature of and the time taken by this immersion treatment depend upon the nature of the layer and upon the kind of organic substance.
- the organic substance selected is a substance the oxidation products of which can be dissolved out without trouble from the absorbent layer on the reduction of the silver salt, so that none of them remain behind in the layer.
- the metallic silver precipitated in the layer is present in an ultramicroscopically fine state. It can readily be reoxidised to a silver compound.
- Such prepared articles for example sheets of metal, can be employed in a similar manner for photographic purposes, e. g., as photographic plates on glass or as prepared films or papers.
- photographic negative and developed in a suitable mineral or organic developer; the pictures produced may be toned, intensified, reduced and fixed in the known manner.
- after-treat the oxidic layer in the known manner after finishing the photographic representation i. e., by colouring it or recompressing it or to thicken the silver image to produce relief by galvanic plating,
- Example 2 A sheet of pure aluminium is anodically treated with a current density of 2 amperes per square decimetre in the following solution at 58 C. with direct current for 35 minutes.
- the layer obtained in this way is non-transparent and of a whitish light grey.
- finished shaped articles or parts thereof or pieces produced from profiles may be employed. After rinsing, the sheet etc. is treated in a solution at 60 C. of gms.
- the sheet etc. After thoroughly rinsing in water and after drying, the sheet etc. is exposed beneath a transparent photo graphic negative, developed in a photographic developer, toned in a gold toning bath, fixed and rinsed. Finally, for the purpose of closing the pores, it is after-treated in a hot solution of a nickel salt or in boiling Water. A photographic copy of a clear effect which is rich in contrasts is produced.
- Example 3 A sheet of pure aluminium 0.25 mm. thick is anodised for 35 minutes in an aqueous solution, free from sulfuric acid, of 6% of chromic acid and 1% of titaniumpotassium oxalate at C. with a current density of 1 ampere per square decimetre.
- the whitish oxide layer produced is then dyed violet in a 1% solution of dihydroxyfiuorescein (gallein).
- dihydroxyfiuorescein gallein
- the sheet is then exposed, in a closed vessel at dark-room illumination or in the dark, to the action of a damp atmosphere containing elementary chlorine gas.
- the silver is oxidised to silver chloride.
- the sheet is first rinsed with a very dilute solution of sodium carbonate and then with clean water and allowed to dry.
- the sheet prepared in this way is excellently suitable, especially in conjunction with an acid, so-called physical developer, for the production of black-andavhite reproductions, for example for the photographic reproduction of cards and incombustible documents or for the production of sign-boards and absolutely correct scales and rules.
- a method of producing a photographic reproduction surface comprising the steps of providing an adsorbent, firmly adhering aluminum oxide layer on an aluminum or aluminum alloy base by subjecting the aluminum or aluminum alloy base to anodic oxidation with direct current in an aqueous solution containing free oxalic acid and an alkali oxalate, said solution having a pH between about 1.2 and 4.0; treating the aluminum oxide layer with a first solution containing an organic reducing agent capable of reducing silver compounds and of being mcrdanted to the aluminum oxide layer; treating the layer with a second solution containing a silver compound reducible by said reducing agent, thereby to mordant metallic silver to the oxide layer; and then treating the layer with an acid aqueous medium containing at least one free halogen until the conversion of the metallic silver into silver halide is completed.
