Title: Process for printing unions

Abstract: The unions consist of a mixture of fibers which can be colored with disperse dyestuffs and fibers which can be colored with reactive dyestuffs. A printing paste containing: (a) at least one finely dispersed, water-insoluble azo dye-stuff of the formula: ##STR1## (b) at least one reactive dyestuff and (c) at least one non-ionic surfactant is used. The azo dyestuff of formula I is not prepared in the printing paste. It has a melting point between 220.degree. and 300.degree. C. In the formula, A, D and R have the meanings given in claim 1. In this way, prints are obtained, from which the non-fixed dyestuffs can easily be washed out and which have an excellent white ground. The build-up and fastness properties are good. The prints are very brilliant and deep in color, in particular in the field of orange and red shades.
