ABSTRACT:
This invention relates to a process for the production of resists or multicolor effects on natural or synthetic polyamide fiber materials, which, to produce resists, comprises locally applying a liquid preparation wet-on-wet before or after treating the textile material with a dyeing liquor or printing paste containing at least one anionic dye, said preparation comprising one or more than one compound of formula ##STR1## wherein R.sub.1 is a straight-chain or branched C.sub.10 -C.sub.24 alkyl or alkenyl radical, R.sub.2 and R.sub.3 are each independently of the other C.sub.1 -C.sub.4 alkyl, X is the radical of an anion, and the benzene nucleus A may be further substituted, or which, to produce multicolor effects, comprises locally applying one or more than one liquid preparation wet-on-wet before or after treating the textile material with a dyeing liquor or printing paste containing at least one anionic dye, said preparation comprising containing, in addition to one or more than one compound of formula (1), at least one anionic dye, and lastly subjecting the textile goods to a heat treatment to fix the dye. Excellent resists or multicolor effects are obtained by the process of this invention.
