| The invention relates to azoxy dyes of general formula (I) in their free acid form, in which n is 0 or 1, R<1> is methoxy, hydroxyl and carboxyl, R<2> is carboxyl, amine, C1-C4 alkylamine, allylamine, benzylamine and methoxycarbonylmethylamine and the phenyl rings A can be substituted with C1-C8 alkyl, phenyl that can be substituted with methyl or halogen, hydroxyl, amine, nitro, halogen, carboxyl, N-benzylcarbamoyl, phenylcarbamoyl and naphthylcarbamoyl that can be unsubstituted or substituted with nitro, halogen, C1-C4 alkoxy, acetoxy, or they can be benzo-anellated. The invention also relates to their Cu complexes, to a method for producing the Cu complex dyes, to azoxy dyes of formula (I) in their partially or completely deacylated form, to their Cu complexes, to dyes containing said azoxy dyes and/or to their Cu complexes and to their use for dyeing and printing natural or synthetic substrates. | ||||||

| The present invention relates to compounds of formula (I): (I) wherein R1 is a dye, and L1, R2 and R3 are as defined herein. The compounds of the invention reversibly convert from a hydrophobic form to a hydrophilic form upon contact with water and carbon dioxide. The present invention also relates to methods of dyeing fibres, and methods of decolouring dyed fibres. The method is particularly useful for dyeing polyester fibres. | ||||||

| Reactive azo dyes having the formula (I), in which A stands for the residue of a diazo component and X is a fibre-reactive heterocyclic residue, are prepared by saponifying maleinylated azo dyes having the formula (IV), then by reacting them with reactive components having the formula X-hal without previously isolating them. The remaining substituents have the meanings given in the description. | ||||||
