Abstract

382,483. Photographic diazotype layers. KALLE & CO. AKT.-GES., 23, Rheinstrasse, Biebrichon- Rhine, Germany. Jan. 18, 1932, No. 1469. Convention date, Jan. 16, 1931. [Class 98 (ii).] Light-sensitive layers are produced by applying a mixture of a diazosulphonate and a diazo compound on a suitable base such as glass, metal, paper or cellulose ester film. The mixture may also be incorporated in the base. Examples are given of mixtures of (1) the sodium salt of naphthalene-#-diazo-N-sulphonic acid and the cadmium chloride double salt of 1-ethylamino-4-diazonaphthalene ; (2) the sodium salt of 1-benzoylamino-2 : 5-diethoxy-4- diazobenzene-N-sulphonic acid and the cadmium chloride double salt of 4-diethylamino-2-hydroxy-1-diazobenzene in a mixture of alcohol glycerine and butyl alcohol (3) the sodium salt of 4-chloroanisol-2-diazo-N-sulphonic acid and either the cadmium chloride double salt of 4-diethylamino-2-hydroxy-1 - diazobenzene or the sodium salt of 1-diazo-2-hydroxy-3-benzoic acid. The usual additions such as. antiyellowing agents may be made to the layer. The layers are developed by washing in water. Specifications 210,862 and 296,725, [both in Class 98 (ii), Photographic processes &c.], are referred to.
