Process for the production of azo dyes |
| abstract |
Azo dyes are prepd. by coupling a diazo cpd. contg. a metal-complex-forming substituent adjacent to azo gp. with a cpd.: (in which one X is -SO3H and the other X is H or -SO3H and Z is NH2 or N-contg. gp. reducible to NH2), and resulting dye is metallised with Cu. |
