摘要：
A monoazo compound of the following formula, ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are independently hydrogen or alkyl, R.sub.4 is alkyl or carboxy, A is ##STR2## in which R.sub.5 is hydrogen, methyl, methoxy, ethoxy, sulfo or carboxy, X is hydrogen or sulfo, n is 0 or 1, and the asterisked linkage bonds to the azo group, B.sub.1 and B.sub.2 are independently phenylene or naphthylene, W is hydrogen, carbamoyl, sulfoalkyl, cyano, sulfo, chloro or bromo, and Y.sub.1 and Y.sub.2 are independently --CH.dbd.CH.sub.2, --CH.sub.2 CH.sub.2 OSO.sub.3 H or the like, which is useful for dyeing hydroxy group- or carbonamide group-containing materials in a deep yellow color excellent in various fastness properties such as light fastness, perspiration-light fastness and chlorine fastness.
