Abstract
The present invention relates to a process for the preparation of finished dyeings of high fastness to thermomigration on fibre materials consisting completely or partly of polyester, characterized in that the material is dyed with one or more dyestuffs of the general formula I ##STR1## wherein R denotes linear (C.sub.1 -C.sub.3)-alkyl or (C.sub.3 -C.sub.6)-alkyl which is interrupted by an oxygen atom and R.sup.1 denotes (C.sub.1 -C.sub.4)-alkyl, and the dyeing thus obtained is then finished.
Claims20
A dyeing and finishing process resulting in dyeings which are highly fast to thermomigration on fibre materials containing polyester, characterized in that the material is dyed with one or more dyestuffs of the general formula ##STR8## wherein R denotes linear (C.sub.1 -C.sub.3)-alkyl or (C.sub.3 -C.sub.6)-alkyl which is interrupted by an oxygen atom and
- R.sup.1 denotes (C.sub.1 -C.sub.4)-alkyl,
- and the dyeing thus obtained is then finished.
A process for dyeing and finishing resulting in dyeings which are highly fast to thermomigration on fibre materials containing polyester, comprising dyeing the material with one or more dyestuffs of the general formula (I) ##STR14## wherein R denotes linear (C.sub.1 -C.sub.3)-alkyl or (C.sub.3 -C.sub.6)-alkyl which is interrupted by an oxygen atom and
- R.sup.1 denotes (C.sub.1 -C.sub.4)-alkyl,
- and finishing the material.
