The invention relates to compounds of formula ##STR1## wherein the variables are as claimed in the claims and which are suitable as fibre-reactive dyes for dyeing a wide range of fibre materials.

Reactive azo dyes containing an aminocarbonyl or aminosulfonyl bridge

Anthraquinone dyes of the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 independently of one another are hydrogen or are substituted or unsubstituted C.sub.1 -C.sub.12 alkyl,

Fibre-reactive anthraquinone dyes, process for their preparation, and

Reactive dyes of the formula ##STR1## in which the variables have the meanings stated in the claims, are described. The dyes according to the invention are particularly suitable for dyeing cellulosic fibre materials and give dyeings with good fastness properties and a high color yield.

Fiber-reactive dyes having a central 1,3,5-triazine ring to which are

Reactive dyes of the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.4 alkyl,
