A heterocyclic compound of the formula, ##STR1## wherein A and B are each hydrogen, alkyl or alkoxy, Y is hydrogen, alkyl, alkoxy or --O--R.sup.2 --X--R.sup.1, or Y and B are taken together with each other to form methylenedioxy, R.sup.1 is alkyl, phenyl or alkenyl, R.sup.2 is unsubstituted or substituted alkylene, and X is --O--, --S--, --SO--, --SO.sub.2 -- or ##STR2## in which R.sup.3 is hydrogen or alkyl, with the proviso that R.sup.1 is C.sub.3 or C.sub.4 alkyl or alkenyl, or C.sub.1 -C.sub.4 alkyl when R.sup.2 is unsubstituted ethylene or propylene, respectively, X is --O-- or --S--, and Y and B don't form methylenedioxy, which is useful for dyeing or printing hydrophobic fiber materials with superior dyeability to give a dyed or printed product of a red color excellent in fastness properties, particularly those such as washing fastness.

Benzodifuranone compounds useful for dyeing or printing hydrophobic

A monoazo compound of the formula, ##STR1## wherein D is a heterocyclic or carbocyclic compound residue such as benzothiazolyl and phenyl, X is hydrogen, alkyl, alkoxy, halogeno, acylamino or the like, Y is hydrogen, halogeno, alkyl, alkoxy and the like, R.sub.1 is alkyl, R.sub.2 is C.sub.2 -C.sub.4 alkylene, B is a bridging group such as ##STR2## --O--, --S--, C.sub.1 -C.sub.6 alkylene and the like, and W.sub.1, W.sub.2, W.sub.3, Z.sub.1, Z.sub.2 and Z.sub.3 are independently hydrogen, alkyl, halogeno or the like, which is useful for dyeing hydrophobic fiber materials to give dyed or printed product of a deep color excellent in fastness properties, particularly those such as washing fastness, even after various finishing treatments of the product.

Monoazo-disperse dye compounds their production and their use

A disperse dye composition comprising (a) a pyridone monoazo compound of the formula (I), ##STR1## wherein X.sup.1 and X.sup.2 are each hydrogen, halogen, alkyl, alkoxy or others, and R.sup.1 is alkyl, alkenyl, cycloalkyl, phenyl or anilino, and (b) a pyridone monoazo compound of the formula (II). ##STR2## wherein X.sup.3 and X.sup.4 are each hydrogen, halogen, alkyl, alkoxy or others, and R.sup.2 is alkyl, alkenyl, cycloalkyl, phenyl or anilino, optionally together with (c) a quinophthalone compound of the formula (III), ##STR3## wherein Y is hydrogen or bromine, and the ring A is unsubstituted or substituted benzene or naphthalene ring, which is useful as a yellow dye component for dyeing or printing hydrophobic fiber materials with superior dye bath stability and level dyeing property.

Disperse dye composition useful for dyeing of printing hydrophobic fiber

A monoazo compound of the following formula, ##STR1## wherein X is a hydrogen or halogen atom, or a C.sub.1-4 alkyl, C.sub.1-4 alkoxy, C.sub.1-4 alkylsulfonyl, C.sub.1-4 alkylcarbonyl, C.sub.1-4 alkoxycarbonyl, nitro, cyano or trifluoromethyl group, Y is a hydrogen or chlorine atom or a methyl or acylamino group, and Z is a hydrogen or chlorine atom or a methyl, methoxy or ethoxy group, which is useful for dyeing or printing hydrophobic fibers with superior level dyeing and build-up properties to give dyed products of a brilliant color superior in fastness properties.

2,6-dicyano-4'-morpholinoazobenzene compounds useful for dyeing

A monoazo pyridone compound of the following formula, ##STR1## wherein X is a member selected from hydrogen, halogeno, alkyl, alkoxy, alkylcarbonyl, alkoxycarbonyl, aralkoxycarbonyl, alkylsulfonyl, arylsulfonyl, carbamoyl, sulfamoyl or cyano, and R is alkyl, alkenyl, cycloalkyl, phenyl or anilino, with the provisos that X is a member selected from those defined above except for hydrogen, chloro, methyl and methoxy when R is ethyl, and X is a member selected from those defined above except for alkyl when R is iso-butyl, which is stable under dyeing conditions, and useful for dyeing hydrophobic fiber materials to give dyed products of a deep, fast and brilliant color of greenish yellow to orange.
