Abstract
The invention relates to reactive dye mixtures comprising the reactive dyes of the formulae ##STR1## in which X.sub.1, X.sub.2 and X.sub.3 are reactive radicals bonded via a diaminoalkylene bridge and the other substituents are as defined in claim 1. The reactive dye mixtures are suitable for dyeing and printing cellulosic fibre materials and give wet- and light-fast dyeings in luminous blue shades.
