<p>The use of an aqueous dispersion paint (A) with a pigment content of 40-200 wt.% (based on polymer component) is claimed for coating buildings or parts of buildings, where the polymer component comprises an emulsion copolymer, 0.5-30 wt.% of which is derived from polyoxyalkylene (meth)acrylate monomers (I). (A) include novel paints (A'), containing other specific monomers in addition to (I). The use of an aqueous dispersion paint (A) with a pigment content of 40-200 wt. % (based on polymer component) is claimed for coating buildings or parts of buildings, where the polymer component comprises an emulsion copolymer, 0.5-30 wt.% of which is derived from monomers of formula (I). R1 = H or Me; X = divalent polyoxyalkylene group having 1-50 oxyalkylene units; and R2 = H or 1-20C aliphatic or aromatic hydrocarbyl (preferably 1-4C alkyl). An Independent claim is included for a novel aqueous dispersion paint (A') comprising a pigment and an emulsion copolymer, where the pigment content is 40-200 wt.% based on the copolymer content, the copolymer has a glass transition temperature below 30 degrees C and the copolymer comprises (wt.%) (1) 1-8C alkyl (meth)acrylates and/or vinyl aromatic compounds (40-99.5) (2) monomer (I) (0.5-30); and (3) further monomers (0-50).</p> |
