    Abstract: Products of the condensation of sulphonated phenols, urea, further organic nitrogen bases and formaldehyde, obtainable by (A) sulphonation of phenols using from 1.0 to 1.5 mol of sulphuric acid per mole of phenol and (B) condensation of these sulphonation products with (a) from 0.5 to 1.8 mol of urea per mole of phenol, (b) from 0.001 to 0.5 mol of at least one further organic nitrogen base per mole of phenol, and (c) from 1.0 to 3.0 mol of formaldehyde per mole of phenol. The condensation products are suitable as tanning agents in the production of leather and pelts and as spray assistants for redispersible polymer powders.
