    Abstract: of the disclosure: Coumarin compounds of the general formula (1) (1) in which A denotes an oxygen atom or grouping ?N-R in which R represents a hydrogen atom or an alkyl radical of 1 to 18 carbon atoms which may be substituted by fluorine, chlorine or bromine atoms or by alkoxy , dialkyl amino, -SO2-N(alkylC1-C4)2 or cyano groups or a cycloaliphatic, aromatic or heterocyclic radical which may be substituted by fluorine, chlorine or bromine atoms or by alkyl , alkoxy , hydroxyl, cyano, sulfonamide or -SO2-N-(alkylC1-C4)2 groups, X denotes an oxygen atom or a grouping ? N-R' in which R' represents a hydrogen atom or an alkyl carbonyl, alkoxy carbonyl, alkyl carbamoyl or alkyl sufonyl group or an aryl, arylcarbonyl, arylcarbamoyl or arylsufonyl radical which may be substituted by fluorine, chlorine or bromine atoms or by alkyl or alkoxy groups of 1 to 4 carbon atoms each or by cyano groups, Y denotes a hydrogen atom or a cyano or an alkyl carboxylate group, an aryl, arylsulfonyl or -CO-O-aryl radical which may be substituted by fluorine, chlorine or bromine atoms or by alkyl or alkoxy groups of 1 to 4 carbon atoms, or by nitro, methylenedioxy, amino, monoalkyl C1-C4 amino or dialhyl C1-C4 amino groups or by a benzoxazolyl radical, or a heterocyclic radical which may be quaternized and which may be substituted by fluorine, chlorine or bromine atoms or by alkyl or alkoxy groups of 1 to 4 carbon atoms, or by nitro, phenyl, alkylphenyl, alkoxy C1-C4 phenyl, cyano, methylenedioxy or alkyl C1-C4 carboxylate groups, and Z denotes a hydrogen atom or an alkyl C1-C4 carboxylate or cyano group, a process for their preparation, and their use for dyeing or printing synthetic fiber materials, in particular polyester fibers.
