    摘要： An improved process for producing discharge reserve prints on textile materials comprising water-repellent fibers or mixed water-repellent and cellulose fibers wherein a disperse dyestuff which is dischargeable to white is applied to the textile material in the form of a dye liquor or dye printing paste, at least partially drying the textile material, applying a discharge reserve printing paste to the material by printing on the material in the desired pattern and subsequently heating the printed material at temperatures from 100.degree. to 230.degree. C., with the improvement comprising (a) the discharge reserve printing paste containing, as the discharging agent, an alkaline material which produces a pH value of at least 8 in 5% strength aqueous solution and (b) the disperse dyestuff which is dischargeable to white is a disperse dyestuff of the formula ##STR1## as more fully defined herein.
