| titleOfInvention | Coumarin dyestuffs |
| abstract | Disclosed are cationic dyestuffs being coumarin or coumarinimide derivatives free from sulpho groups, bearing a 7-amino group and being characterized by having, in the 3-position, a cationic group of formula (a), <IMAGE> (a) in which A(-) signifies an anion, either R5 DEG signifies hydrogen or optionally substituted alkyl or cycloalkyl, and R6 DEG signifies hydrogen, or optionally substituted alkyl or cycloalkyl, or, where R5 DEG is hydrogen, also hydroxy, naphthyl, optionally substituted amino or alkoxy, or phenyl monosubstituted by phenoxy, chlorophenoxy, benzyl, amino or C1-C4 alkylamino, or R5 DEG and R6 DEG , together with the nitrogen to which they are attached, signify a non-aromatic heterocycle, and the dotted line indicates that the positive charge is not localized, their production and use for dyeing and printing basic dyeable substrates, plastics and paper, particularly acid modified polyester substrates. They give dyeings of yellow to greenish yellow which fluoresce in the yellow to greenish yellow band. |
