Sizing agents which are novel compounds and have at least one anionic or acidic group which is optionally in salt form and at least two hydrophobic substituents of which at least two of the most adjacent ones are bonded to each other with a bridging member which has at least 1 carbon atom and 2 hetero atoms, at least one sulfur atom being present as hetero atom, in particular sulfimides or bisulfimides of fatty acid derivatives, are highly suitable for use, together with commercially available retention aids, in a process for sizing paper or cardboard.

Sizing agents, which are novel compounds and contain at least one anionic or acidic sulfonylcarbonylimide group which may be in salt form and at least two hydrophobic substituents of which at least two are linked to each other through a bridge member of the formula --CO--NH--A.sub.1 --(SO.sub.2 --NH--CO).sub.t, where A.sub.1 is a divalent or trivalent aliphatic, cycloaliphatic or aromatic radical of up to 10 carbon atoms, and t is 1 or 2, are particularly suitable, together with commercially available retention aids, for use in a process for sizing paper or cardboard.

An anionic adsorbent which has been prepared by reacting (a) a monomeric compound which contains at least one anionic group and at least one amide group, especially a carboxamide group, which can be methylolated, with (b) an aminoplast precondensate which is free from salt-forming anionic groups. The novel adsorbent is particularly suitable for removing cationic substances, such as cationic dyes, and a heavy metal ions from aqueous solutions, especially from effluents.
