    摘要: Water-soluble fiber-reactive dyes which contain one or more groups of the general formula (1) ##STR1## where R.sup..alpha. and R.sup..beta. are each hydrogen or lower alkyl,R is hydrogen or sulfoY is vinyl or ethyl which is substituted in the .beta.-position by a substituent which is eliminatable under alkaline conditions,W is hydroxy, N-morpholino, N-piperidinyl, N-pyrrolidinyl or a group of the general formula (2) ##STR2## where G is hydrogen or alkyl of 1 to 6 carbon atoms andQ is a group of the general formula (2a), (2b), (2c) or (2d) ##STR3##--(CH.sub.2).sub.t --R.sup.a (2b)--(CH.sub.2).sub.t --O--(CH.sub.2).sub.w --R.sup.a (2c)--(CH.sub.2).sub.t --R.sup.2 (2d)whereR.sup.a is a group of the general formula --SO.sub.2 --Y, where Y is as defined above, or sulfo,R.sup.b is hydrogen, alkoxy of 1 to 4 carbon atoms, sulfo, hydroxy, carboxy or chlorine,R.sup.c is hydrogen, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms,t is from 1 to 6 andw is from 1 to 6, orW is a radical of the general formula (2e)--A--(CH.sub.2).sub.r --R.sup.a (2e)whereR.sup.a is as defined above,r is zero, 1 or 2, andA is a radical of the general formula ##STR4##
