    • In order to achieve lighter patterned effects on a background of a deeper color, aqueous printing pastes containing, additionally to thickeners and other conventional printing assistants, assistants which have dissolving properties for the dyestuffs at elevated temperatures and which do not attack the fibers under thermosol conditions, are applied to textile webs which have been dyed in a finished manner with suitable dyestuffs or have only been impregnated therewith, after which the goods treated in this way are subjected to a steaming process or to a dry heat treatment. In accordance with the process it is possible to effect a uniform lightening, "white discharging" or "colored discharging" of dyeings, particularly dyeings of synthetic fibers with disperse dyestuffs and also dyeings of natural fibers or mixtures thereof with disperse dyestuffs, vat dyestuffs, leuco esters thereof and developing dyestuffs. Dyestuff-dissolving assistants of the type used are anionic, cationic or nonionic compounds of various structures.
    • 为了在更深色的背景上获得更轻的图案效果,除了增稠剂和其它常规印刷辅助剂之外还含有水性印刷浆料,在高温下对染料具有溶解性能的助剂,并且在热溶胶条件下不会侵蚀纤维 适用于已经用合适的染料以最终方式染色或仅被浸渍的织物网,然后以这种方式处理的物品进行蒸煮处理或干热处理。 根据该方法,可以实现均匀的减轻,染色的“白色放电”或“着色排出”,特别是具有分散染料的合成纤维的染色,以及天然纤维或其与分散染料,瓮染料的混合物的染色, 其无色酯和显影染料。 所用类型的染料助剂是各种结构的阴离子,阳离子或非离子化合物。

    • In the process for the pad-dyeing or printing of materials consisting of, or containing, polyester or polyamide fibers or filaments, in which process the materials are padded or printed in common manner with aqueous baths or printing pastes of disperse dyestuffs, and the dyestuffs are subsequently fixed by the action of liquid or gaseous methylene chloride or both of the said phases of methylene chloride, the improvement that use is made of a dyestuff of the formula ##STR1## in which R.sub.1 stands for hydrogen, hydroxy, nitro or ##STR2## R.sub.2 and R.sub.3 each stand for hydrogen, chlorine or alkyl from 1 to 3 carbon atoms or an alkoxy group of from 1 to 3 carbon atoms, R.sub.4 represents hydrogen, chlorine, alkyl from 1 to 3 carbon atoms, an alkoxy group from 1 to 3 carbon atoms or --CH.dbd.CH--CH.dbd.CH-- forming the naphthalene ring, and R.sub.5 stands for hydrogen, alkyl from 1 to 3 carbon atoms or alkoxy from 1 to 3 carbon atoms, which dyestuffs have a solubility in methylene chloride of at least 2 g/l.
