ABSTRACT:
The dyes according to the invention consist of a chromophore and a radical which, on heating, forms an isocyanate or isothiocyanate group. The latter reacts with a suitable group in the environment. Dyeings of excellent thermomigration fastness are obtained. The disclosed dyes are of the formulae ##STR1## where F is the radical of an azo, anthraquinone or tricyanovinyl dye which is free of water-solubilizing groups,
