Claims
- 1. A monoazo compound represented by the following formula in a free acid form, ##STR83## wherein A in phenylene unsubstituted or substituted with methyl, methoxy, chloro, carboxy or sulfo, or naphthylene unsubstituted or substituted with sulfo, R.sub.1 and R.sub.2 are independently hydrogen, chloro, methyl, nitro, carboxy or sulfo, provided that R.sub.1 and R.sub.2 cannot both be hydrogen and R.sub.1 is sulfo located at o-position to --NHCO-- and R.sub.2 is hydrogen when A is phenylene, and X is --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 Y in which Y is a group splittable by the action of an alkali.
- 2. A monoazo compound represented by the following formula in a free acid form, ##STR84## wherein R.sub.1 and R.sub.2 are independently hydrogen, chloro, methyl, nitro, carboxy or sulfo, excepting the case
- where both R.sub.1 and R.sub.2 are hydrogen, and X is --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 Y in which Y is a group splittable by the action of an alkali.
- 3. A monoazo compound represented by the following formula in a free acid form, ##STR85## wherein the methoxy is located at 2- or 4-position.
- 4. A monoazo compound represented by the following formula in a free acid form, ##STR86## wherein R.sub.3 is chloro, methyl, nitro, carboxy or sulfo.
- 5. A monoazo compound represented by the following formula in a free acid form, ##STR87## wherein R.sub.3 is chloro, methyl, nitro, carboxy or sulfo.
- 6. A monoazo compound represented by the following formula in a free acid form, ##STR88##
- 7. A monoazo compound represented by the following formula in a free acid form, ##STR89##
- 8. A monoazo compound represented by the following formula in a free acid form, ##STR90##
- 9. An aqueous liquid composition comprising a monoazo compound represented by the following formula in a free acid form, ##STR91## wherein A is phenylene unsubstituted or substituted with methyl, methoxy, chloro, carboxy or sulfo, or naphthylene unsubstituted or substituted with sulfo, R.sub.1 and R.sub.2 are independently hydrogen, chloro, methyl, nitro, carboxy or sulfo, provided that R.sub.1 and R.sub.2 cannot both be hydrogen and R.sub.1 is sulfo located at o-position to --NHCO-- and R.sub.2 is hydrogen when A is phenylene, and X is --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 Y in which Y is a group splittable by the action of an alkali.
