Abstract

In the 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 disperse dyestuffs and reactive dyestuffs which react with the resisting agents, drying or partially drying the padded materials and subsequently printing a resist paste on the material, and heat-treating the materials the improvement comprises the dischargeable disperse dyestuffs being of a class of dyestuffs of which an exemplary species is ##STR1## one of the tautomeric forms of a class of dyestuffs of which an exemplary species is ##STR2## or disperse dyestuffs which are free from groups conferring solubility in water and which contain at least two carboxylic acid ester moieties.
