NEW MATERIAL:A compound of formula I [M is H, alkali metal; R<0> is H, COOH; R<1> is H, lower alkyl, lower alkoxy, COOH, SO3H; R<2> is H, lower alkyl, lower aloxy, acetylamino, SO3H, R<3> is lower alkyl, lower alkoxy; R<4> is H, lower alkyl, acetylamino, P is halogen, -SO2R<5> (R4u5 is lower alkyl); Q is halogen, CN, NO2, -SO2R<5>; W is halogen, R<5>; m is 1-3; n is 0, l; rings A, B are benzene rings, naphthalene rings]. EXAMPLE:The compound of formula II. USE:Dyes dyeing cellulose fiber or cellulose-polyester blend fiber green with high dyeability and fast fastness to light, base, sweat and sun light. PREPARATION:Compounds of formula III-V are diazotized and coupled to give a disazo compound of formula VI. In the meantime, the compound of formula VII is allowed to condense with the compound of formula VIII to give the compound of formula IX, then the product is allowed to couple with the compound of formula VI.
