Abstract
Dye bases of the general formula:-<FORM:0747083/IV(c)/1> wherein R1, R2 and R3 are alkyl groups, and R4 is an alkyl or alkoxy group, R2 and R1 together containing less than 12 carbon atoms, and the corresponding compounds wherein the benzene ring may carry alkyl, alkoxy, aryl or halogen substituents, are made by reacting the corresponding meso substituted methyl thiacarbocyanine dye salts as described in Specification 717,858, with a strong base such as an alkali metal hydroxide or alkoxide, sodamide or trimethyl benzyl ammonium hydroxide. The reaction may be carried out by refluxing in pyridine or ethanol. In the above formula the alkyl groups may contain up to four carbon atoms or may be higher alkyl groups and the alkoxy groups may be derived from such alkyl groups. Examples are given wherein the central carbon atom carries acetylcarbethoxymethylene, diacetylmethylene, or acetylcarbomethoxy methylene groups.
