Abstract
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, and R.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.
