Abstract:
The present invention relates to the use of aqueous multistage polymer dispersions obtainable by free-radically initiated aqueous emulsion polymerization, having a soft phase and a hard phase and having a hard-to-soft stage ratio of 25% to 95% by weight to 75% to 5% by weight, the glass transition temperature (Tg) of the soft phase, as first stage, being −30 to 0° C. and that of the hard phase, as second stage, being 20 to 60° C., comprising at least one monomer of the general formula I in which the variables have the following definitions: n=0 to 2, R1, R2, R3=independently of one another hydrogen or methyl group, X═O or NH, Y═H, alkali metal or NH4, to coat metal sheets.
Abstract:
The present invention provides the use of aqueous polymer dispersions comprising (a) at least two monomers M1 having a glass transition temperature ≥25° C., (b) at least two monomers M2 having a glass transition temperature
