Dimetyl-, diethyl-, and ethylene ethers of aminocatechol were synthesized. Those were condensed with β-hydroxynaphthoic acid to give azoic coupling components. p-Nitroaniline and 2-chloro-4-nitroaniline were diazotized and coupled with aminocatechol dimethyl- and -diethyl ether to give aminoazo compounds as azoic diazo components, and their coloration and fastness have been invb-stigated.<BR>The coupling components synthesized gave nearly the same coloration as that of Naphthol AS-BG, among which ethylene derivative gave a clear blue coloration when combined with Fast Blue BB and its fastness was about the same as that of Naphthol AS-BG. The diazo components generally colored in brownolive green, their fastness was 6 grade for light and superior for washing and rubbing.
