Abstract

Printed textiles and a process for production of resist effects on textile materials of mixed fibers of polyester and cellulose comprising impregnating the materials with a dye liquor containing dischargeable disperse dyestuffs and dischargeable reactive dyestuffs which react with the resisting agents, drying or partially drying the materials and subsequently printing a resist paste on the materials, and heat-treating the materials at temperatures of 100.degree. to 190.degree. C., PA0 the improvement comprises said dischargeable disperse dyestuffs are of the formula ##STR1## p0 wherein n is a number of 1 to 9; said dischargeable reactive dyestuffs being those containing reactive moieties of the formula PA1 --SO.sub.2 --CH.sub.2 --CH.sub.2 --hal, PA1 --SO.sub.2 --CH.sub.2 --CH.sub.2 --O--SO.sub.3 M, PA1 --NH--SO.sub.2 --CH.sub.2 --CH.sub.2 --O--SO.sub.3 M or PA1 --SO.sub.2 --CH.dbd.CH.sub.2 PA0 wherein M is hydrogen or a metal cation and hal is halogen; and PA0 the resist paste contains an alkali metal sulphite or an alkali metal bisulphite in combination with an alkali metal carbonate of alkali metal bicarbonate.
