Abstract: The use of certain dyes for detecting cracks is claimed. The dyes are opt. metallised phthalocyanines and naphthalo-cyanines, aminium cpds. of aromatic amines, methine dyes or azulene-squaric acid dyes with an absorption max. in the 600-1200 nm range and a fluorescence max. in the 620-1200 nm range.

Abstract: 4-Formylaminopiperidine derivatives of the formula (I) (II) where n is 1 or 2, R1 to R4 are each alkyl or R1 and R2 or R3 and R4 are tetra- or pentamethylene, R5 is hydrogen or alkyl, R6 is hydrogen, unsubstituted or substituted alkyl, alkenyl, aralkyl or acyl, and, when n is 1, Y is hydrogen, unsubstituted or substituted alkyl, alkenyl, cycloalkyl, bicycloalkyl, aralkyl, aryl, alkyl containing heterocyclic radicals, or or, when n is 2, Y is alkylene, cycloalkylene, aralkylene or arylene or is alkylene which is interrupted by oxygen, nitrogen, sulfur or a 5-membered or 6-membered heterocyclic structure, and their acid addition salts have very good stabilizing properties in plastics.

Abstract: Azulene squaric acid dyes containing ester groups, of the formula in which L denotes C1-C12-alkylene which is optionally substituted by phenyl, R denotes C1-C12-alkyl, mono- or polyunsaturated C1-C12-alkenyl, which can be substituted by phenyl, C5-C7-cycloalkyl, C5-C7-cycloalkenyl, optionally substituted phenyl, pyrrolyl, furanyl, thienyl or pyridyl and R , R , R and R independently of one another denote hydrogen or optionally substituted C1-C12-alkyl, with the proviso that if R denotes hydrogen, the ring positions of the substituents CH2-L-O-CO-R and R on one or both azulene rings can also be interchanged with one another within an azulene ring, their intermediates and an optical recording medium which contains the novel dyes.
