    Abstract: Azo dyes having a 2,6-diamino-pyridine as coupling component, one of the amino groups bearing a bicyclic or polycyclic non-aromatic radical as a substituent. The dyes are eminently suitable as disperse dyes, particularly for synthetic linear polyesters, and give bright dyeings having excellent fastness properties.

    Abstract: 1438156 Disperse azo dyes of the 2,6-diaminopyridine series BASF AG 19 Oct 1973 [21 Oct 1972] 48764/73 Heading C4P [Also in Division C2] Disperse dyes of the 2,6-diaminopyridine series have the formula where D is the radical of a diazo component; R is H, unsubstituted or substituted alkyl of 1-7 C, or unsubstituted or substituted phenyl; Z is H, carbamoyl or CN; and one of the radicals X and Y is acyl and the other is H, or unsubstituted or substituted alkyl, cycloalkyl, aralkyl or phenyl. D may be optionally substituted phenyl, phenylazophenyl, benzthiazolyl, benzisothiazolyl, thiazolyl thiadiazolyl and thienyl. The dyes are produced by diazotization and coupling, and give yellow to blue shades with textile materials such as acrylonitrile polymers, synthetic polyamides, cellulose acetates, and particularly synthetic linear polyesters such as polyethylene glycol terephthalate.

    Abstract: Title derivs. have the formula: (where n is 0 or 1; R is carboxyl, 2-8C (substd.) carbalkoxy or (substd.)carbonamide; R1 is cyano, carboxyl, (substd.)carbalkoxy or (substd.)carbonamide and B is: where R2 and R3 = H or alkyl; X is H, 1-5C alkyl, methoxy or ethoxy and Y is H, sulphonic acid or (substd.)sulphonamide). The cpds. can be used to dye e.g. polycaprolactam.
