Azophenyl compounds |
abstract |
Azophenyl compounds of formula (I), wherein R1 is an o-, p-directing substituent; R2 is a substituted or unsubstituted beta -hydroxyalkyl group; R3 is an aromatic carbocyclic or heterocyclic group which is mono-or poly-cyclic and is substituted or unsubstituted; and wherein the benzene ring A may contain one or more further substituents. The compounds are useful as dyestuffs (if they are themselves coloured) or as intermediates in the preparation of dyestuffs. |
