Zusammenfassung: | NEW MATERIAL:The compound of formula I [X1 is H, methyl, methoxy or sulfonic acid group; X2-X4 are H, Cl, methyl, methoxy, carboxyl or sulfonic acid group; Y is H or sulfonic acid group; Z is Cl, F, -N(R)3 (R is 1-4C alkyl) or group of formula II or III (M is H or alkali metal)] as free acid. EXAMPLE:The compound of formula IV. USE:A dye for dyeing a cellulosic fiber in brownish color. It has excellent color yield and build-up property. PREPARATION:The compound of formula I (Z is Cl or F) can be produced e.g. by condensing cyanuric chloride or cyanuric fluoride in the form of free acid to the aminoazo compound of formula VI and a chromium complex compound derived from the aminoazo compound of formula V (as free acid). |
