METHOD FOR SUBSIDING OF VACCUM DEPOSIT SILVERHALODE LAYERS

摘要

The method is used for microphotographic purposes, as well as for preparing media for digital laser recording. Layers with fine-grained texture are obtained, which result in improving the contrast, the resolution and the sharpness of the image. Maximum resolution of 1600 - 3300 lines/mm is typically achieved for the dotted layers. The method involves dotting vacuum-cladded silver-halogenide layers with metals of IV a and IV b groups of the periodic system and/or their oxides, and/or sulphides, and/or selenides, and/or tellurides at the rate of 1.10<-6> to 1.10<-2> percent (w/w) when dotting inside the layer and 7.10<-13> to 1.10<-6> percent (w/w) when dotting the layer surface. Arsenic and germanium, as well as oxides and halogenides thereof, have been tested in particular.
