摘要:
The present invention relates to a new dyeing process based on the exhaustion principle. It is characterized in that dyeing liquors are used which, in addition to the dyestuff or dyestuff mixture, contain one or more salts, at least one compound having a glycidyl radical and, if appropriate, further auxiliaries.
