    Abstract: PROBLEM TO BE SOLVED: To obtain a new polyazo dyestuff having black color and blue to navy blue color, excellent in light fastness and moisture fastness, and useful for dyeing cotton, wool, leather, polyamide fibers, etc. SOLUTION: A compound of formula I [one of X , X is hydroxyl group, and the other is amino; (p), (q) are each 0, 1; D , D are each a group of formula II (R is H, a 1-4C alkyl, a halogen, etc.; R is H, hydroxysulfonyl, etc.); B is SO2 -NH-A -NH-SO2 (A is phenylene, etc.), etc.]. For example, a compound of formula III. The compound of formula I is obtained by combining a monoazo dyestuff of formula IV with a tetrazonium salt derived from a bisamino compound of formula V.

    Abstract: Bis(5-azo-6-hydroxy-4-methyl-3-hydroxysulphonyl-pyrid-2-on- 1-yl) dyes (I) of formula (A), in the form of free acids or their salts, are claimed. In A, A and Y are each -SO3H; Z is D-N=N-; D is the residue of a diazo component; and X is a 2-8 C alkylene opt. with an ether O atom in the chain. Also claimed are bis(6-hydroxy-4-methy-3-hydroxysulphonyl-pyrid-2-on-1-yl) cpds. (II) of formula (A), in which Y is -SO3H and Z is H, in the form of the free acids or salts, and the prepn. of (II).
