Abstract:
Anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone and perylenetetracarbimide dyes which contain one or two groups of the general formula ##STR1## where Y is vinyl or an ethyl group which contains in a .beta.-position a substituent which is eliminable by means of alkali to form a vinyl group, and W is a direct bond or a group of the general formula ##STR2## where M is a hydrogen atom or an alkali metal and n is zero, 1 or 2.
