Process for preparing azo dyestuffs containing 2,4,6-tri-amino-3-(cyano ester or carbonamide)pyridine |
| abstract |
Azo dyestuffs free of sulphonic acid groups and carboxylic acid groups are prepared by coupling a diazo compound with a coupler which is prepared by reacting an organic amine with a pyridinium salt having the formula ##STR1## IN WHICH R is substituted or unsubstituted alkyl, cycloalkyl, aralkyl or aryl; and n R 1 is substituted or unsubstituted alkyl or aralkyl. The dyestuffs are suitable for dyeing and printing synthetic materials such as polyolefines, polyvinyl compounds, cellulose acetate and triacetate and polyesters to give yellow to blue dyeings and prints with good fastness properties especially to light and sublimation. |
