    Abstract: The invention relates to azoxy dyes of general formula (I) in their free acid form, in which n is 0 or 1, R is methoxy, hydroxyl and carboxyl, R 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.

    Abstract: The invention relates to the use of compositions which contain as components: A) at least one bisazo compound selected from the group consisting of the compounds of general formula (Ia), and general formula (Ib) wherein R is C1-C8 alkyl, R is C2-C8 alkyl, R , R is C2-C21 alkyl, wherein up to four CH2 groups of the carbon chain can be substituted by oxygen in the ether function, R is hydrogen or may independently of R have the meaning of R , R is hydrogen or may independently of R have the meaning of R ; B) at least one solvent in which component A) is soluble and optionally C) at least one surface-active substance. Said compositions are used as fissure-detection agent for detecting surface fissures or other defects in work pieces to be examined. The invention further relates to compositions containing the above-mentioned components A), B) and C).
