• ##STR139## wherein R.sup.2 and R.sup.3 each independently represent a hydrogen atom or a lower alkyl group which may be optionally substituted, R.sup.4 represents methyl or methoxy, U represents an alkylene which may be optionally interrupted by amino, carbamoyl, ureido or an oxygen atom, and * indicates a bond to an azo group,
• B.sup.1, B.sup.2 and B.sup.3 each independently represent a direct bond or a connecting group represented by the following general formula (3):
• ##STR140## wherein, R.sup.5 represents a hydrogen atom or a lower alkyl group which may be optionally substituted, ** indicates a bond to --NR.sup.1 --, --NR.sup.2 -- or --NR.sup.3 --,
• Z.sup.1 represents an alkylcarbonyl group which may be optionally substituted or a phenylcarbonyl group which may be optionally substituted, or a group represented by the following general formula (4a) or (4b), and
• Z.sup.2 and Z.sup.3 each independently represent a group represented by the following general formula (4a):
• ##STR141## wherein, both X.sup.1 and X.sup.2 represent chloro, or X.sup.1 represents fluoro, chloro, pyridinio group which may be optionally substituted, or a group represented by the following formula (5a):
• ##STR142## and X.sup.2 represents a group represented by the following general formula (5b), (5c), (5d) or (5e):
• ##STR143## wherein, A.sup.1 and A.sup.2 each independently represent alkylene which may be optionally substituted, phenylene which may be optionally substituted or naphthylene which may be optionally substituted, R.sup.6, R.sup.7, R.sup.8, R.sup.9 and R.sup.10 each independently represent a hydrogen atom, alkyl which may be optionally substituted or phenyl which may be optionally substituted, O represents --CH.sub.2 --, --O--, --S--, --SO.sub.2 -- or --NR.sup.11 -- wherein R.sup.11 represents a hydrogen atom or alkyl which may be optionally substituted, n is 1, 2 or 3,
• X.sup.3 represents fluoro or chloro,
• X.sup.4 represents chloro, hydrogen atom, methyl or cyano,
• Y, Y.sup.1 and Y.sup.2 each independently represent --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 L wherein L represents a group which is eliminatable by the action of alkali, and
• a group represented by --NR.sup.1 is linked to 6-position or 7-position of the naphthalene ring;
• provided that,
• when D represents a group of the formula (2a) or (2b) and B.sup.1, B.sup.2 and B.sup.3 represent a direct bond,
• and Z.sup.1, Z.sup.2 and Z.sup.3 each a group represented by the following general formula (4a),
• then, the general formula (4a) represents a group represented by the following general formula (4a-1) or (4a-2):
• ##STR144## wherein, A.sup.1, A.sup.2, R.sup.6, R.sup.7, X.sup.2, Y.sup.1 and Y.sup.2 are as defined above, X.sup.1 * represents fluoro or chloro, X.sup.2 * represents a group represented by the general formula (5b), (5c), (5d) or (5e) or a pyridinio group which may be optionally substituted, and Z.sup.1 and Z.sup.2 do not simultaneously represent the general formula (4a-1) and Z.sup.1 and Z.sup.3 do not simultaneously represent the general formula (4a-1);
• and when D represents a group of the formula (2a) or (2b), B.sup.2 and B.sup.3 represent a direct bond, Z.sup.1 represents an alkylcarbonyl group which may be optionally substituted or a phenylcarbonyl group which may be optionally substituted and B.sup.1 represents a direct bond, then Z.sup.2 and Z.sup.3 represent a group represented by the general formula (4a-2).
