Photocoloration System Containing Diazonium Salts as Initiators

Abstract

Colored materials which differed from the azo dye were formed, when the photocoloration systems consisting of diazonium salts and dye bases, such asstyryl bases and ind61e groups, were exposed to light.
The colored material producced from diazonium salt and 4-(p-dimethylaminostyryl)quinbline was identical with the dye from carbon tetrabromide and 4-(P-dimethylaminostyryl)quineline in the free radical-photography. The colored material formed in the diazonium salt-indole system was, different from the dye formed in the carbon tetrabromide-indole system.
