The invention relates to novel cross-linkable monomers that may be polymerized with ethylenically unsaturated comonomers to form cross-linkable copolymers. Said copolymers may particularly be used in the form of aqueous dispersions as formaldehyde-free adhesives or as coatings with good water resistance. The cross-linkable monomer is a compound in acid or salt form comprising an anion of the formula (I) and one or more cations for producing electrical neutrality, where R
