Abstract
A monoazo compound useful for dyeing or printing a fiber material represented by the following general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or alkyl; U.sup.1 and U.sup.2 represent a group of the following general formula (U1), (U2) or (U3): ##STR2## wherein Y.sup.1, Y.sup.2 and Y.sup.3 represent --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 Z wherein Z represents a group which can be eliminated by the action of an alkali; and X.sup.1 and X.sup.2 represent halogeno, pyridinio or a group of the following general formula (X1), (X2), (X3) or (X4): ##STR3## or a salt thereof.
Claims20
A monoazo compound represented by the following general formula (I):
- ##STR352## wherein R.sup.1 represents a hydrogen atom or alkyl which may be optionally substituted;
- D represents a group of the following general formula (II) or (III):
- ##STR353## wherein * indicates the bond attached to the azo group, R.sup.2 represents a hydrogen atom, lower alkyl, lower alkoxy, or sulfo, and
- p and q, which are the same as or different from each other, each represent 0 or 1;
- U.sup.1 and U.sup.2, which are the same as or different from each other, each represent a group of the following general formula (U1), (U2) or (U3):
- ##STR354## wherein R.sup.3, R.sup.4 and R.sup.5, which are the same or different from each other, each represent a hydrogen atom or alkyl which may be optionally substituted,
- A.sup.1 represents phenylene which may be optionally substituted or naphthylene which may be optionally substituted,
- A.sup.2 represents alkylene which may be optionally substituted,
- Q.sup.1 represents --O--, --S-- or --NR.sup.6 -- wherein R.sup.6 represents a hydrogen atom, alkyl which may be optionally substituted or phenyl which may be optionally substituted,
- r and s, which are the same as or different from each other, each represent 2, 3 or 4, and
- Y.sup.1, Y.sup.2 and Y.sup.3, which are the same as or different from each other, each represent --CH=CH.sub.2 or --CH.sub.2 CH.sub.2 Z wherein Z represents a group which can be eliminated by the action of an alkali;
- and
- X.sup.1 and X.sup.2, which are the same as or different from each other, each represent halogeno, pyridinio which may be optionally substituted or a group of the following general formula (X1), (X2), (X3) or (X4):
- ##STR355## wherein R.sup.7, R.sup.8, R.sup.9 and R.sup.10, which are the same as or different from each other, each represent a hydrogen atom, alkyl which may be optionally substituted, phenyl which may be optionally substituted or naphthyl which may be optionally substituted,
- Q.sup.2 represents --CH.sub.2 --, --0--, --S--, --SO--, --SO2-- or --NR.sup.11 - wherein R.sup.11 represents a hydrogen atom or alkyl which may be optionally substituted, and
- t represents 1, 2 or 3;
- with the proviso that at least one of X.sup.1 and X.sup.2 represents pyridinio which may be optionally substituted or a group of the general formula (X1), (X2), (X3) or (X4);
- or a salt thereof.
