ABSTRACT:
A process for the dyeing or printing and simultaneous finishing of cellulose materials is disclosed the said process comprises impregnating these materials with an aqueous liquor containing a specific dyestuff which contains at least one bis-hydroxy-alkylamino group bound to a pyrimidine or triazine nucleus and bridged via an amino group to the dyestuff molecule, synthetic resin forming intermediate or aminoplast, an acid catalyst and optionally further additives, thereupon drying the thus impregnated material or steaming or storing at room temperature and finally subjecting it to a treatment at elevated temperature and optionally washing.
The dyeings thus obtained have especially very high fixing yields of the dyestuffs and are moreover fast to light and to washing and have further finishing effects such as, e.g. improvement of the handle and resistance to shrinkage.
