  • (a) 20 to 90% by weight of an acrylic acid and/or methacrylic acid alkyl or cycloalkyl ester having 1 to 10 carbon atoms in the ester group;

    (b) 80 to 10% by weight of an acrylic and/or methacrylic acid ester with an aromatic group as the ester group or containing an aromatic group in the ester group;

    (c) 0 to 5% by weight of a copolymerizable carboxylic acid;

    (d) 0 to 10% by weight of a copolymerizable ureido compound; and
