Abstract

A dyestuff of the formula ##STR1## WHEREIN X.sub.1 represents fluorine, bromine, chlorine or hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, phenyl, phenoxy, thiophenoxy or C.sub.1 -C.sub.4 -alkyl sulphonyl, C.sub.1 -C.sub.4 -alkylthio, each of which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkoxy, hydroxy, cyano, bromine, chlorine, carbo-C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkoxy-C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylcarbonyloxy, chloro-C.sub.1 -C.sub.4 -alkylcarbonyloxy or C.sub.1 -C.sub.4 -alkoxy-carbonyloxy, fluorine, bromine, chlorine, COOR, in which R represents C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkyl substituted by C.sub.1 -C.sub.4 -alkoxy, hydroxy, cyano, C.sub.1 -C.sub.4 -alkylcarbonyloxy, chlorine or bromine, --SO.sub.2 NH--C.sub.1 -C.sub.4 -alkyl and ##STR2## (WHEREIN THE C.sub.1 -C.sub.4 -alkyl is unsubstituted or substituted by hydroxy, chlorine, bromine, C.sub.1 -C.sub.4 -alkoxy or phenyl), --SO.sub.2 -alkyl or CN; X.sub.2 represents methoxy, ethoxy, methyl or hydrogen, X.sub.3 represents hydrogen, alkyl containing up to 4 carbon atoms, chlorine, bromine, ##STR3## (WHEREIN ALKYL IS SUBSTITUTED OR UNSUBSTITUTED), NITRO, OR SO.sub.2 --R, wherein R represents alkyl or substituted or unsubstituted phenyl, n is 0, 1 or 2, and the dotted ring can represent a fused benzene ring. The new dyestuffs dye polyester fibers in bright red shades.
