New reactive-disperse dyes

ABSTRACT

Four new reactive-disperse, 4 new disperse and 2 new reactive dyes were synthesised. The molecule of the reactive-disperse dye contains as a reactive hook an epoxide ring in which a 4-nitrophenyl group substituted at one of its carbon atoms, meanwhile is considered as a derivative of 2,4-dinitrodiphenyl-amine thus acquiring the properties of disperse dyes. The present reactive-disperse dyes are useful for dyeing polyester-cotton blends
