    • Prints on cellulose-containing materials with water-soluble dyes, e.g. acid or direct dyes, are after-treated with a mixture of quaternary polyalkylene polyamines and hardenable resin precondensates and subsequently heated to 100-180 DEG C., preferably 130-160 DEG C. The specified quaternary compounds are those obtainable by reacting ditertiary ethylenediamines with aliphatic dihalogen compounds, by alkylating, e.g. with dimethyl sulphate, polyethylene polyamines prepared from ethyleneimine, ethylene dichloride and ammonia or chloroethylamine hydrochloride and sodium hydroxide or polypropylene polyamines prepared from 1-amino-3-halogeno-propane or from the sulphuric acid ester of 1-amino-3-hydroxy-propane. The specified resin precondensates are dimethylol-urea, dimethylol-ethylene-urea, dimethylol-dihydroxy-ethylene-urea, tetramethylol-acetylene-diurea, hexamethylol-melamine and pentaerithrityl-tetra-(N-methylol-methylcarbamate) as well as their alkyl esters. In the examples cotton fabrics are printed, dried, steamed, washed and again dried and then impregnated with an aqueous solution containing the above specified compounds, squeezed, dried at 80-100 DEG C. and heated at 100 DEG C. for 5 minutes, soaped, rinsed and dried. Specifications 761, 668, 803, 322, 879, 635 and 887, 358 are referred to.
