摘要
NEW MATERIAL:A compound in the form of a free acid expressed by formula I {R1 is H, halogen, cyano, carbamoyl, etc.; R2 is H, alkyl or lower alkoxy lower alkyl; R3 is methyl or COOH; R4 is H, methyl or sulfonic acid; R5 is H or lower alkyl; Z is halogen, formula II (R6-1 and R6-2 are H, alkyl, etc.) or formula III [R7 is H or (substituted) lower alkyl; Y is -SO2CH=CH2, etc.; X is (substituted) phenylene, etc.]; m is 0 or 1}. EXAMPLE:A compound expressed by formula IV. USE:A coloring matter for dyeing cellulose and nitrogen-containing fibers to a yellow color. PREPARATION:An aniline compound expressed by formula V is condensed with a triazine compound expressed by formula VI (Z' is halogen) to give a diamino compound expressed by formula VII, which is converted into a tetrazo compound. The resultant tetrazo compound is then subjected to coupling reaction with a pyridone based compound expressed by formula VIII.
