Abstract
Continuous dyeing and printing of cellulose fibre material by impregnating the material with a 2-hydroxy-naphthalene-3-carboxylic acid phenyl amide, alkali and nitrite, by crosspadding or over-printing with a dispersion or emulsion of a 4-amino-diphenyl amine as well as acid or acidic salt, and bringing about the development of the dyestuff by drying the fiber material and/or exposing it to sodium carbonate.
