摘要： PROBLEM TO BE SOLVED: To obtain a fiber-reactive dye which has high tinting strength and high fiber/dye bonding stability for especially a cellulosic fiber material and has good fastness to light and good fastness to humidity by selecting a dye having a molecular structure containing a 5,6-difluoropyrimidin-4-yl residue being a fiber-reactive group. SOLUTION: This dye is represented by the formula: Fb-Zn (wherein Fb is a residue of a sulfo-containing mono-, dis- or poly-azo dye or a residue of a heavy metal complex mono-, dis- or tris-azo dye or a residue of an anthraquinone, azomethine, phenazine, formazan, phthalocyanine or like dye; n is 1, 2 or 3; Z is a group represented by formula I [wherein Q is a covalent bond or a group of formula II (wherein RA is H, a halogen, hydroxyl, a 1-4C alkyl or the like): W is a covalent bond or a bridge-forming factor; and Q is necessarily a covalent bond when W is a covalent bond; and R is H, a halogen, hydroxyl, a 1-4C alkyl which may be substituted or the like].

摘要： Fibre reactive azo dyes of formula (I) are claimed, where D is a residue of diazo component of the benzene- or naphthalene series; K is a coupling component of formula (II); M is H or alkali metal, a = 0 or 1, b = 0 or 1 and the bond marked with * is connected to the azo group; R is H or optionally substituted 1-6C alkyl; R is H or optionally substituted 1-6C alkyl; Y is bonded to the amino residue -NR - or -NR - and is a residue of formula (III); R is H, optionally substituted 1-4C alkyl or optionally substituted phenyl; A is amino, cyanamino, 1-4C alkoxy, phenoxy, the residue of a heterocyclic compound in which the ring contains a N atom and optionally another hetero atom, alkylamino in which the alkyl has 1-4C and may be substituted by substituents selected from sulpho, carboxy, Me, Et and OEt, dialkylamino with 1-4 alkyl residues which may be substituted by substituents selected from sulpho, carboxy, Me, Et and OEt, or a phenylamino group which is optionally substituted in the phenyl residue; c = 0 or 1; G is an optionally substituted phenylene; B is a 1-6C alkylene or ethylene-oxy-ethylene; X is beta -hydroxyethyl, vinyl or ethyl that is substituted in the beta -position by a substituent that can be eliminated by alkali; and Z is bound to the amino residue -NR - or -NR - and is a heterocyclic fibre- reactive residue which is different to Y.

摘要： Sulfonated formazan and copper formazan dyes (I), mono, di- or tri-substituted by 5,6-difluoro-pyrimidin-4-yl-amino, are new. Sulfonated formazan and copper formazan dyes of formula (I), mono, di- or tri-substituted by 5,6-difluoro-pyrimidin-4-yl-amino, are new: D-(Z) n (I) D : the residue of a sulfonated formazan or copper formazan dye; n : 1, 2 or 3; Z : a group of formula (II): [Image] Q : a covalent bond, -N(R A>)-, -CO-N(R A>)- or -SO 2-N(R A>)-; R, R A>hydrogen (H) or 1-4 carbon (C) alkyl, optionally substituted by halogen, hydroxy (OH), cyano (CN), 1-4 C alkoxy, 2-5 C alkoxycarbonyl, carboxy, sulfamoyl, sulfo, sulfato or phosphato; N(R A>) and N(R) : amino groups attached to a C atom of W or a C atom of a substituent on W; W : a covalent bond or bridging group provided that if W = a covalent bond then Q = a covalent bond. An independent claim is also included for the preparation of dyes (I).
