Summary:NEW MATERIAL:Dis-azo compounds of formula I wherein R is CH3, C2H5 ; the ring A is a benzene ring, or a naphthalene ring ; m is 0-3 ; the sulfo group attached to the naphthalene ring B is bonded to the naphthalene ring B at position 6 or 7 against the azo group attached to the ring A. EXAMPLE:Compound of formula II. USE:Vinylsulfone type reactive dyes which dye cellulosic fibers dense brown with good fastness. PREPARATION:A monoazo compd. of formula III (wherein A, m naphthalene ring B are as defined above) is diazotized and then coupled with an alkylaniline of formula IV (wherein R is as defined above). The resulting org. compd., 3- aminophenyl-beta-sulfatoethylsulfone and cyanuric chloride are condensed together to produce the compd. of formula I .
