| abstract | 848,458. Diazotype processes. ILFORD Ltd. Nov. 22, 1957 [Nov: 23, 1956], No. 35886/56. Class 98(2) Diazotype material containing a diazotized amine of the formula:- wherein R1 is an alkyl group of 1 to 3 carbon atoms and R2 is H or a methyl group in 3<1>-, 5 <1>- or 61-position, or the corresponding amines in which the indicated CH3 group is in 4<1>-position, is developed in an alkaline medium in the presence of a 1:3:4-cyclopentatrione which may have an alkvl, arvl or aralkyl group in the 2-position. The diazonium compound may be 4-p-tolylthio- 21, 5-diethoxy-benzene diazonium zincichloride or 21, 5-dimethoxy-4 (2<1>-methyl-phenylthio) benzene diazonium zincichloride. The coupler may be 1; 3; 4-cyclopentatrione or its 2-phenyl derivative, and it may be present in the light-sensitive material or in the alkaline developer solution. The developer may contain potassium tetraborate and sodium lauryl sulphate with or without potassium carbonate. Specification 759,045 is referred to. |
