Abstract:
The present invention relates to primer compositions in powder form that comprise a dispersion powder based on an acrylate polymer having a glass transition temperature in the range from −50° C. to +30° C. and cement. The compositions of the invention are notable for good water barrier effect, good dust-binding capacity, and a low tendency toward salt efflorescence. The encompositions find use in the priming of masonry, concrete, rendered surfaces, abraded render, plaster surfaces, wall blocks, wood, and ceramic tiles. They can also be used as adhesion promoters with nonabsorbent substrates such as glazed ceramic or glass tiles, metal surfaces, or surfaces of plastic.

Claim (Index 11):
The primer composition according to  claim 1 , wherein the polymer comprises units derived from:\n 50 to 80 wt %, of the first monomer, 15 to 40 wt %, of a second monomer, 0.5 to 15 wt %, of a third monomer, and 0 to 10 wt %, of a fourth monomer, based in each case on a total monomer amount, wherein the second monomer is copolymerizable with the first monomer and is at least one selected from the group consisting of a vinylaromatic compound and a vinyl or allyl ester of a C 1 -C 12  carboxylic acid, the third monomer is copolymerizable with the first and second monomers and is at least one selected from the group consisting of an \u03b1,\u03b2-ethylenically unsaturated C 3 -C 6  monocarboxylic acid or C 4 -C 8  dicarboxylic acid, (meth)acrylamide, a N,N-mono-di-C 1 -C 4 -alkyl(meth)acrylamide, (meth)acrylonitrile, an N-vinyl derivative of a cyclic lactam, a hydroxy-C 2 -C 4 -alkyl (meth)-acrylate, and an N,N-mono- or di-C 1 -C 4 -alkyl-aminoalkyl(meth)acrylate, and the fourth monomer is copolymerizable with the first, second and third monomers and is a compound comprising at least two nonconjugated, ethylenic double bonds.
