Abstract: The invention relates to compounds which, in the form of the free acids, correspond to the general formula I in which l is the number 0, 1 or 2, m is the number 0 or 1, n is the number 1 or 2, l + m is at least 1, K is the radical of a coupling component and X is a reactive group, where, for n = 2, X corresponds to the formula -X -B-X - in which X and X are reactive radicals and B is a bridge member, and in which the naphthalene radical can additionally be substituted by hydroxyl and the phenylene ring by chlorine, bromine, methyl, ethyl, hydroxyl, methoxy, ethoxy or carboxyl. The compounds according to the invention are suitable for dyeing fibres containing hydroxyl groups, in particular cotton.

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.
