Abstract
Process for the preparation of reactive dyes, characterized in that an organic dye D-H, containing at least one replaceable hydrogen atom, is reacted with a radical-introducing compound I ** (See formula) ** in which of Z1, Z2 and Z3, one Z means fluorine and the other two Z, as well as R, independently of each other, means hydrogen or any monovalent substituent, X means a monovalent negative substituent or a bivalent negative group that is linked with Y, Y means a bivalent bridge member, which is composed of one or more heteroatoms or of an organic radical which may contain heteroatoms, and n means a positive integer value of 2 at most and in which Y is also directly linked with the benzene ring, to form dyes of the general formula II ** (See formula) ** in which Z1, Z2, and Z3, R, Z, Y and n have the meaning already expressed, m means a positive integer value of 2 at most and D means the radical of an organic dye.
