Process for dyeing and printing cellulose-containing materials characterized in that neutral alkali metal dyebaths or printing pastes are used for the preparation of which a preferably aliphatic amine having at least one amino group separated from an oh group by two carbon atoms is used. Carbon a compound containing anions of a phosphoric acid, an alkali-resisting medium yielding copper and a metal-free dye that forms a complex containing as metallizable groups exclusively O-oxycarboxylic acid groups and also at least two azo groups whose dye forms copper compounds which are difficult to dissolve, to which effect the dye must be chosen, whose copper compound segregated from alkaline medium passes into solution at least 90º, with the addition of a double amount of 1,2-di- (beta-oxyethylamino) -ethane and when dissolving in a quantity of water 50 times greater than the boiling temperature.
