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).
