Definitions

  • the oxygencontaining layer be sufliciently porous to absorb the light-sensitive substances. Furthermore it is necessary that the layer have no -disturbing color.
  • an oxalic acid bath and a direct electric current are suitable as his known per se, for producing the oxygen-containing. layer.
  • the layer has generally a yellowish color and is therefore not proper for photoof certain aluminum alloys, for instance duralumin, a 'glasslike, bright layer can be developed which has also a small power for' absorbing solutions or suspensions oi! light-sensitive substances.
  • a 'glasslike, bright layer gives 8. spotted photograph "with an unequal distribution of shadow. It has suiilciently. but it has a. matt aspect and no me tallic lustre which is however 0! great importance -ibt,nhotomphic representations in order to reach excellentTclearness and eilectoi space.
  • taining layers especially suitable for photographic purposes can be produced, according to this invention, ,in the following manner: Any articles of aluminum or an aluminum alloy, say, plates,
  • foils or films are first dipped in one bath, under conditions producing an oxide coating thereon, and then in a second bath containing other chemical agents, under conditions producing the accession of additional oxide coating.
  • the aluminum article In each bath the aluminum articleis connected as an electrode and subject to the effect of an electric current, flowing through the bath. It is preferred to connect the aluminum articles as anodes to a source of direct current. The best results are somewhat better. if the representation, after being photographicaliy' produced, fixed and toned is filled or coated with oil,-fat or with wax or lac.
  • the sheet with the layer canbe impregnated with a solution oi ammonium chloride and then with a solution of silver nitrate.
  • silver chloride is deposited within the poresof the oxygen-containing layer; After drying a colorlessiayer exists upon which representation posure to light in a photographic apparatus.
  • the metallic lustre remains at thosesp tsoi the oxide lsyerwhich are and written characters oi'yerygood quality n 9 be formed by a. copying method or by direct exnot influenced by light during the photographicprocedures. The aspect of the photographic representation is then very good.
  • the part oi -the figure to the left oi! the arrow represents a possible structure of an' aluminum plate after treatment in the first coating bath of our invention, while The part of the figure to the right of the arrow represents a possible structure of the plate. after the second coating operation and after impregnation with photo-sensitive materials.
  • Fig. 2 shows a plate or film which has been further subjected to the second anodic treatment of our invention, as well as having been impregnated with photo-sensitive salts or a sensitized emulsion.
  • the initial oxide coating 2 is represented as having been dissolved to.
  • the second oxide layer 4 is indicated in Fig. 2 as extending into the aluminum plate or film'to a somewhat greater depth than the initial coating 2. Also that the top of the initialcoating 2 is shown at a level lower than a. This is, of course, purely hypothetical, since the exact nature and structure of the two coatings is not known. It is known'that the initial layer is porous and that after the second layer has been deposited the coating as a whole presents a somewhat greater metallic lustre and appears to be capable of being impregnated somewhat more uniformly. This is believed to indicate the possibility of thepresence of a larger Y number of finer pores, after deposition of the secand layer.
  • a direct current can be employed. It is possible to employ a direct current in the first bath and an alternating current in the second bath or vice versa.
  • the steps which comprise treating a sheet of aluminum composition electrolytically in an aqueous coating bath containing a solution oi chromic acid having a concentrationof about 20 per cent, under conditions producing a porous oxide layer thereon, then treating the resulting oxide.
  • coated article electrolytically in a bath containing an aqueous solution of oxalic acid having a concentration of about 3 per cent, under conditions producing the accession of additional porous oxide coating, and impregnating the resulting coating with photo-sensitive materials.
