Abstract

Water-soluble anthraquinone compounds of the formula (1) ##STR1## wherein M is a hydrogen atom or the equivalent of a metal, such as in particular sodium or potassium, R is a hydrogen atom, a halogen atom, the methyl, ethyl, methoxy, ethoxy or carboxy group, and X is the vinyl group, a .beta.-thiosulfatoethyl, .beta.-sulfatoethyl or the .beta.-chloroethyl group. These compounds may be prepared in a manner know by itself by reacting an anthraquinone compound of the formula (2) ##STR2## wherein M is defined as above, with an equimolar quantity of cyanuric chloride and an amine of the formula (4) ##STR3## wherein R and X are defined as above, or by reacting said anthraquinone compound of the formula (2) with a compound of the formula (5) ##STR4## wherein R and X are defined as above. The new compounds of the formula (1) are valuable dyestuffs having fiber-reactive properties. When applied to materials containing hydroxy and/or carbonamide groups, preferably fiber materials, these dyestuffs yield strong and fast dyeings and prints or high tinctorial strength; for example, they are particularly suitable for dyeing (and printing) cellulose fiber materials and wool having an anti-felt or …
