Description

Process for the production of arts and crafts. Addition to the patent 607 0I2 Patent 607 0.2 uses oxide layers on aluminum and its alloys as a carrier for photosensitive, without binders in the Oxydic layer embedded substances for the production of characters, images etc. placed under protection.

We have now succeeded in making those made of aluminum or an aluminum alloy existing objects, which are impregnated with an oxidic, with silver salts Layer provided and exposed according to the pattern, on pictures or handicrafts To further process objects that produce the most diverse effects allow. For this purpose, the object exposed according to the pattern is physically developed, until a coherent, electrically conductive silver deposit arises. These silver deposits can then be galvanically coated with coatings made of other metals such as copper, nickel, gold, chromium, etc. Special Effects can be achieved by the fact that the picture background is not covered by the silver is colored with dyes of all kinds. One can do two-tone in this way Patterns obtained, one of which is colored by the color of the metal, the other is determined by the dye.

Another embodiment of the process ordered that one also stains the galvanic metal deposit. So you can z. B. Copper precipitation color green, black or brown in a known manner. You can get tin precipitation color black, green or red etc. The examples can be multiplied at will. One can also color the oxide layer and the galvanic deposit combine.

Another application of the process is that you can use the galvanic Make the edition so strong that a relief is created. Such reliefs can be used as high or gravure printing plates can be used for all printing processes.

If the precipitation is increased even more, one finally reaches a strength, by which the words could be replaced mechanically or mechanically. You then get, depending on the pattern you use, e.g. 13. Letters made of copper or Gold, filigree-like structures made of metals, which nian independently for different arts and crafts or artistic activities, e.g. B. as book decoration, Cushions on leather work or glass, etc. can be used. From @ tthrungsbelSpiele I. An oxide layer is produced on aluminum or an aluminum alloy. This will. as written in the # main patent. impregnated with @hlrsiilber and after the exposure under a negative. a drawing or the like, physically developed, until the exposed areas have a cohesive coating of metallic Show silver. The aluminum object is whitened and after development Electroplated in a copper bath. On the areas covered with silver copper is deposited. The galvanic treatment is continued for a long time. until the desired thickness is reached. After you have taken it out of your copper bath is washed and dried. Then the picture background becomes, dfe after chlorosilver contains. Fixed by treating with 2 sodium thiosulphate and then cloth once washed. Any other metal can be used on the copper bridge afterwards., like Xickel, Cadmiutnm, Chrom etc .. be knocked down. Fed up primarily hop r to be deposited on the silage. can of course also immediately use other metals, such as Gold. Platinum. the aforementioned metals or, if necessary, silver. be deposited for reinforcement.

2. It will be. as described in Example I. photographic images and the silver-plated healings are galvanically treated in a gold bath. To Treatment turns the item into a dye bath. z. B. in an aqueous solution an aniline dye, introduced and left there. until you co-galvanized Parts of the object assumed the desired color). For the purpose the coloring scan it be useful to the original picture according to its physical Entti @ kilunttg do not fix it, as this may result in desired effects dimming can be achieved. All colors can be used for dyeing Dyeing process can be used.

3rd eleven according to example t produced by cruising (item 1 becomes in a bath of water. Sulfur liver and carbonate of ammonia treated. l) Eirimi guessed the copper-plated parts brown. Elen non-galvanized underground can dye inanit using one of the well-known Alutuninitunfärbeverfahren. Similarly, zero nickel, silver. Coloring tin knives, etc.

1. After a drawing. r.B3. a monogranun, is after dlemn Method of the main patent produced a photographic image on aluminum. This purple is physically developed according to Delim's example. until a coherent silver deposit has formed. the now Gal-Vantisch is copper-plated. The copper plating is driven so far that a copper layer Disfigured by one or several tenths of a millimeter. Lousy copper layer is made then replaced by the liter situation. by plan z. ß. dThe Altunminiutnmplatte as Cathode switches in an alkali-containing bath. Instead of electrical replacement you can also remove the precipitate mechanically. z. B. by cutting off with a Sharp blade ollers due to mechanical stress (bending of the base).

It is already known to have a metal surface with a light sensitive Layer of bichronmat containing loin or gelatin to be coated. after the unexposed parts of the layer must be removed and exposed according to a pattern to deposit a galvanic deposit on your exposed metal. From The subject matter of the invention differs fundamentally from these methods. that on the finite impregnated silver halides. atic aluminumotvdi existing Layer after the sealing by means of very smooth physical development cohesive imetallic silver layer produced on the exposed areas on which any metals are subsequently electroplated. The carrier layer of the photosensitive fabrics. dlas aluminum oxvd. is in dliesenm So don't fall away. Eat was therefore not foreseeable. that with her treatment In the galvanic bath, the metal deposit only occurs on the exposed, phootoclhenmisclh silver-plated parts would form. Rather, it was to be expected. dassi at all no or electroplating would occur on the entire surface. since it could not be foreseen in advance that the photochemically separated Silver penetrate through the (Ox @ edsclieht through to the aluminum matrix layer would.
