Abstract

A process for dyeing or printing fiber materials containing hydroxy and/or carbonamide groups, in which process a fiber-reactive, water-soluble dyestuff of the type defined below is applied to the fiber material and is then fixed on the fiber material at an ordinary or elevated temperature, if appropriate in the presence of agents having an alkaline reaction. This water-soluble dyestuff, which contains at least one sulfonic acid group, contains one or more groupings belonging to the group comprising the formulae (1a), (1b) and (1c) EQU --SO.sub.2 --CH.dbd.CH.sub.2 (1a) EQU --SO.sub.2 --CH.sub.2 --CH.sub.2 --Hal (1b) EQU --SO.sub.2 --CH.sub.2 --CH.sub.2 --A (1c) (in which Hal represents a halogen atom and A represents the acyloxy radical of a monobasic or polybasic acid) and also contains, linked to it, a 6-fluoro-1,3,5-triazin-2-ylamino radical, this monofluorotriazinylamino radical containing, in the 4-position, a substituent which is not an N-phenylamino or N-naphthylamino substituent having a group belonging to the above-mentioned formulae (1) attached to the optionally substituted phenyl radical or optionally substituted naphthyl radical, and is also not an amino substituent co…
