ABSTRACT:
According to two-phase processes multi-color effects are obtained on cellulosic materials, namely conversion effects with reactive and vat dyestuffs on the one hand and discharge resist prints with reactive dyestuffs and, optionally, vat dyestuffs on the other hand, by printing or padding the reactive dyestuff or a mixture of reactive and vat dyestuffs in a weakly acidic medium onto the material, overprinting this material with a neutral paste containing a stable discharging agent of the sulfinic acid series and, if desired, a vat dyestuff, drying the print, contacting the material with an aqueous strongly alkaline liquor, steaming it and finishing the article in known manner, depending on the choice of dyestuffs.
