    Abstract: An improved process for production of discharge resist prints on textile material which contain hydrophobic fibers wherein at least one disperse dyestuff dischargeable to white discharge-resistant disperse dyestuff is applied, in the form of a dye liquor or printing paste, to the textile material and a discharge resist printing paste is printed on the material in the desired pattern, and the material is subsequently subjected to heat treatment at 100.degree. to 230.degree. C., wherein the improvement comprises the discharge resist printing paste containing, as the discharging agent, at least one salt of hydrogen sulphide, polysulphanes, compounds have a thiolate group of the formula --S.sup..crclbar. or a tautomerizable thio-group of the formula .dbd.S, and mixtures thereof.
