Aqueous dispersions of (meth)acrylic esters of polymers comprising N-hydroxyalkylated lactam units and obtainable by free-radically initiated emulsion polymerization, wherein monomers copolymerized are (a) styrene, acrylonitrile, methacrylonitrile and/or methyl methacrylate, (b) at least one C1 to C18 alkyl acrylate and/or at least one C2 to C18 alkyl methacrylate, (c) at least one acrylic ester of an N-hydroxyalkylated lactam and/or at least one methacrylic ester of an N-hydroxyalkylated lactam, and (d) if appropriate, other ethylenically unsaturated monomers, and use of these aqueous dispersions and/or of polymers which comprise in copolymerized form at least one acrylic ester of an N-hydroxyalkylated lactam and/or at least one methacrylic ester of an N-hydroxyalkylated lactam for treating the surface of paper and of paper products, and also the inkjet papers obtainable accordingly.
