Abstract
The invention relates to a compound, comprising at least three functionalities, that is (a) a sulfonate or sulfate group of the formula —(O)—SOM with d=0 or 1 and M=hydrogen or a monovalent metal cation or the corresponding fraction of a polyvalent metal cation, (b) a (meth)acryl group, and (c) either (c1) at least one further (meth)acryl group or an inorganically condensable group, and/or (c2) a further carboxylic acid function, and/or (c3) a function which increases the refractive index of a material produced from the compounds, that is a thioether group, with the proviso that a sulfonate or sulfate group and a (meth)acrylate group are separated from one another in a silicon-free compound via a hydrocarbon-containing group, the carbon chain of which is either interrupted by O, S or NH or contains a linking group.
