Fluoreszierender Cyanacrylatklebstoff

The invention relates to an adhesive based on esters of d-cyanoacrylic acid with a pyrylium salt which has the following general formula (I). This formula makes it possible to add a high-concentration dye to the esters of cyanoacrylic acid, without perceptibly impairing the storage stability or the...

Beschreibung
Zusammenfassung:	The invention relates to an adhesive based on esters of d-cyanoacrylic acid with a pyrylium salt which has the following general formula (I). This formula makes it possible to add a high-concentration dye to the esters of cyanoacrylic acid, without perceptibly impairing the storage stability or the adhesive properties. Parent solutions can be prepared, by means of which the cyanoacrylate adhesives can easily be dyed in accordance with the desired application.
