A compound has at least three functionalities, including a first functionality (a) that is a sulfonate group or a sulfate group of the formula —(O).sub.d—SO.sub.3M with d=0 or 1 and with M=hydrogen or a monovalent metal cation or a corresponding portion of a multivalent metal cation; a second functionality (b) that is a (meth)acryl residue; and a third functionality (c) that is a carboxylic acid function and/or a thioether group. When the compound is free of silicon, the sulfonate or sulfate group and the (meth)acryl residue are separated from each other by a hydrocarbon-containing residue having a carbon chain. The carbon chain is interrupted by S or NH, or the carbon chain contains a linking group, selected from C(O)NH, NHC(O), NR.sup.8C(O), NHC(O)O, NR.sup.8C(O)O, NHC(O)NH, C(O)NHC(O) and —C(O)S—, wherein R.sup.8 is alkyl or alkenyl or a (meth)acryl group.
