    Abstract: Some novel diazo compounds, and salts thereof, useful for dyeing keratinous fibers, particularly human hair are disclosed. Illustrative of these compounds are the methyl sulfate salts of 1'-(4'-N,N-dimethylaminobenzene) 2-azo 4-cyano 1-methyl pyridinium methyl sulfate and 1'-(4'-amino 8'-hydroxy naphthalene) 2-azo 1-methyl pyridinium. Hair setting lotions, hair dye compositions and hair lacquers containing these compounds, preferably in alcoholic solutions, are also disclosed.
