SU473150A1 - The method of obtaining a photographic image - Google Patents

Description

This invention relates to a method of imaging a photographic image.

Izvosty a method of obtaining a photographic image by applying a photosensitive layer on the boat, containing a mixture of noble metal, nalladium chloride and a reactive compound, followed by exposure and display.

The disadvantages of this method are the high consumption of noble metal and the use of unstable manufacturers.

The purpose of the invention is to reduce the consumption of the noble metal, which is achieved by the use of copper oxalate as a reactive compound and the development is carried out in a chemical developer.

A substance is chosen as the reactive compound that will form a visible image when interacting with the developer's reagent. When developing, the contact of the reactive compound and the noble metal must not be interrupted. To do this, the noble metal compound is adsorbed on a solid reactive compound or combined with.

The layer that contains the reactive compound and the connection of the noble theta. 1, EXHIBIT, observed the release of the noble. Hopped, on the externally exposed areas (hidden image). The appearance of nvol. t in pro in; body. Contents of the quality of the reconnaissance: o:; ntel. In the course of a nuclear science, food for good): 1 metal 1a is separated; 1 from the reaction 1: special compound with a metal that is visible, but the reaction product, which is also closely related to the reactive compound, is The catalnizer further recods restored. The manufacturer is stable because it does not contain an oxidizing agent.

Get the image chenogch) color on a blue background with koitryastnost. For better preservation, the paper with the ivory image is washed with water or water;

To turn a blue background into white

The paper with the image is placed in the end of the treating solution of the comforter, such as citric acid, and after the background is decolorized, it is washed with water. A dark brown image is obtained on a white background.

Comparative results of the test samples obtained from the proposed and known methods using paper as the starting material are shown in the table.

The manufacturer used in the known method contains 40 ml / l of 37% formalip, 50 g / l of potassium salt of tartaric acid, 15 g / l of caustic patra and 10 g / l of copper sulfate CuSO4 БНоО in water.

The content of Pd ++ in paper is determined photocolorimetrically with n-nitrosodimethylanilium.

Subject invention

A method of obtaining a photographic image by applying a photosensitive layer to a substrate containing a noble metal compound, such as palladium chloride, and a reactive compound that exhibits, exhibits and leads to a PM, characterized in that, in order to reduce the precious metal consumption, as a reactive piece, in order to reduce the precious metal consumption, as a response. the oxalate is taken over the copper layer and the lead is carried out in a chemical industry;
