摘要:
Dyes useful for transfer printing and having the formula ##STR1## in which X and Y are hydrogen or halogen,Z is hydrogen or methyl,R.sup.1 is hydrogen, lower alkyl or alkoxy,R.sup.2 is hydrogen, chlorine, lower alkyl, alkoxy, alkanoylamino or pyrrolidonyl, andR.sup.3 and R.sup.4 are alkyl optionally substituted by alkoxy, chlorine, alkanoyl or alkoxycarbonyl. The dyes are especially useful for the transfer printing of polyamides, giving prints having very good light and wet fastnesses.
摘要:
Azo dyes having a 2,6-diamino-pyridine as coupling component, one of the amino groups bearing a bicyclic or polycyclic non-aromatic radical as a substituent. The dyes are eminently suitable as disperse dyes, particularly for synthetic linear polyesters, and give bright dyeings having excellent fastness properties.
