ABSTRACT:
Monoazo compounds of the formula ##STR1## in which each of R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, signifies a methyl or ethyl radical, which are useful as disperse dyes for substrates comprising or consisting of synthetic or semi-synthetic hydrophobic high molecular weight polymers, e.g., linear aromatic polyesters, cellulose acetates and synthetic polyamides. The dyeings exhibit notable fastness to light, heat treatments, wet treatments, perspiration, solvents, lubricants, rubbing, cross-dyeing, ozone, flue gas and chlorine and resistance to permanent pressing, soil release finishes and reduction.
