摘要

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.
