Aqueous polymer dispersions (I) containing a radically polymerised polymer (II) with a minimum film-forming temperature (MFT) of 15-50 degrees C, derived from (a) 11-35 wt% ethylenic comonomer with at least one hydroxy group, (b) 89-50 wt% principal monomers selected from 1-20C alkyl (meth)acrylates, up to 20C vinyl- aromatic compounds and vinyl esters of 1-20C carboxylic acids, and (c) 0-30 wt% other comonomers. Also claimed are (i) coating materials (III) containing (I), and (ii) coatings obtained from (III). |
