Abstract

347,430. Photographic diazotype layers. KALLE & CO. AKT.-GES., 23, Rheinstrasse, Biebrich-on-Rhine, Wiesbaden, Germany. March 28, 1930, No. 10012. Convention date, March 30, 1929. [Class 98 (ii).] Diazo compounds of aromatic amino compounds substituted by acylamino or thioacylamino group are used in the preparation of light sensitive layers. Tetrazo groups containing two amino groups in the acyl residue may be used. Examples are given of layers containing (1) the tin chloride double salt of tetrazo-diaminodiphenyl-thiourea, boric and tartaric acid and thiourea, (2) tetrazo-diaminotetramethoxy diphenylurea, tartaric acid and thiourea, both layers being developed with phloroglucinol and borax, (3) the zinc chloride double salt of 1-amino-2: 5-diethoxy-4-benzoylamino benzene, 1-hydroxy naphthalene-7-biguanidine, naphthalene trisulphuric acid, boric and tartaric acids, thiourea and ammonium sulphate developed with ammonia or sodium carbonate, (4) the diazo compound referred to under (3) above, boric and tartaric acid and thiourea developed with phloroglucinol, 1: 7-aminonaphthol, 2: 7-dihydroxynaphthalene or 1: 7 hydroxynaphthalene-biguanidine, (5) the zinc chloride double salt of diazo 1-amino-2: 5 dimethoxy-4-benzoylamino benzene, aluminium sulphate, boric and tartaric acids and thiourea, suitable developers being beta-naphthol, resorcine, 1-hydroxynaphthalene-1-biguanidine and 1-hydroxy naphthalene-7-phenyl guanidine.
