Process for the production of light-sensitive aluminum e

plates

The invention relates to a method of manufacture a photosensitive material using anodized aluminum as a support, in particular a method, to effectively enclose a sensitive material such as silver halide and the like in the forums of the oxide layer or to form, which was formed by anodizing the aluminum.

Aluminum is a relatively cheap material which, due to its excellent ductility, is easy to process, is white and light and is hardly amenable to corrosion because it reacts easily with the oxygen in the air to form a stable oxide film Demand for aluminum because of these advantages. On the other hand, aluminum is easily damaged (citrate and the like) due to its low hardness and the self-formed oxide film is occasionally corroded, since it is usually only 5 x 10 " ⁵ to 1.5 x 10 " ⁴ " thick.

To overcome this problem, processes for anodizing aluminum were developed. Duroh dlt after these Method gtbildtttn Alualniuaoxydfilnt is da · Aluai & iua Before Iratstm and lorrosiontn gtsohtttst »

The present invention is concerned with dtr avoidance this error and concerns a method by which the confinement of the sensitive liquid in the pores The film is enhanced by the anodized aluminum plate a vibration from supersonic waves Busätelich to the usual elevator procedure.

Generally speaking, reverberation waves are used to increase the Effective washing in liquids, removal of foams used in liquids and to improve the dispersion of liquids and the like; of the invention when the anodized aluminum plate is immersed in the photosensitive liquid and continuously Supersonic waves of for example 300 W, 29 KC / S are applied, the supersonic waves not only have the effect to blow the air out of the pores in the oxide layer, i.e. a defoaming effect, but also a Effect for simultaneous penetration of the necessary amount of light-sensitive liquid into the pores.

The test results for this are given in Table IA recordedι

example

In a device for irradiation with ultrasound waves ait "ines! The oscillator (1) with an output of τοη 300 V and a resonance frequency of 29 KC / S was added to water (5) and a solution (4) of silver nitrate and a hydrophilic colloid was placed in the vessel (2) which had an oscillating plate . Vorsugsweise the silver nitrate has a Konsentration from 30 to 50 i> and the hydrophilic colloid such from 0.1 to 0.5% after immersion in the solution, the anodized Aluniniumplatte (3) with the überaohallwellen for 15 bie 180 seconds irradiated.

After the irradiation, the liquid adhering to the surface of the plates was removed as far as possible » and after the Trooknung τοη itself or on thermisohea ways the plate was immersed in an aqueous solution of an alkali halide, for example Kaliunbroadd, potassium chloride and the like immersed and old the supersonic waves in the same Irradiated in the same way as standing in the gate, so that the silver halide was formed in the pores. This plate was made with water on removal of the footwear at SaIs washed and naoh stored in a dark tree after drying.

The plate obtained was exposed under a negative film, developed in a photographic developer, fixed and washed in water and then in a Aoldlntensivlerflttsslgkelt intensified and, if necessary, colored, whereupon the pores are filled with a liquid by falling asleep in a hot solution of a Hlckelsalses or were filled in boiling water and thereby a photographic plate copy was obtained, which was of high contrast and was clear, the image obtained being particularly true to light and weather influences.
