ABSTRACT:
A method for reducing the adhesion forces between hard surfaces and subsequently occurring soil is described. The method comprises the step of treating the hard surfaces with a liquid composition comprising special copolymers A. These copolymers A comprise structural units originating froma1) one or more special monomers comprising a cyclic amide structure ora2) one or more special alkoxylated monomers andb) one or more special monomers comprising an amido group and a sulfonic acid group in protonated or in salt formand may be crosslinked or non-crosslinked.
