Abstract
Procedure for the preparation of monoazo compounds that correspond, as free acids, to the formula ** (See formula) ** in which Y1 and Y3 each signify a hydrogen atom or a -NR-Z group; Y2 signifies a hydrogen atom, a -NR-Z group or a sulfonic acid group; Z and X each signify an aliphatic fiber-reactive radical, with two or three carbon atoms; R signifies a hydrogen atom or an alkyl group; the naphthalene nucleus contains a single -NR-Z group; Z and X each have three carbon atoms when Y2 is not a sulfonic acid group; and the benzene radical can contain still other substituents, characterized by comprising the operational groups of coupling, acylation or, in the event that X represents an alpha-bromoacrylic group, optionally hydrobromic acid cleavage.
