摘要:
Dimethine compounds of the coumarin series of the general formula ##STR1## with the substituent meanings given in the description are used for dyeing synthetic fibre materials, in particular those of polyester, polyamide, polyurethanes, polypropylene and polyacrylonitrile. Clear, luminous-red dyeings of high brilliancy are obtained. The dyestuffs can also be used as laser dyestuffs and as energy converters in light-collecting systems.
