Aqueous solutions of N-methylol compounds of carboxylic acid amides, urethanes, ureas and aminotriazines or of N-methylol ethers of these compounds which are suitable for finishing cellulose-containing textile materials are prepared by reacting compounds containing one or more N-H groups with formaldehyde and, in the case of N-methylol ethers, with an alcohol in aqueous solution by adding boron trifluoride, a boron trifluoride addition compound or tetrafluoroboric acid or a salt thereof to the aqueous solutions during or immediately after this reaction. |
