Abstract: PROBLEM TO BE SOLVED: To provide an aqueous dispersion suitable for priming a glasslike substrate, a mineral substrate in particular. SOLUTION: This priming method of mineral substrate comprises a process of applying an aqueous dispersion of composite particles to the mineral substrate. The dispersion is obtained by free-radical emulsion polymerization of a mixture of ethylenically unsaturated alkoxy silane monomer comprising addition polymer and finely particulate inorganic solid, and containing at least one kind of ethylenically unsaturated alcoxy silane monomer, in the presence of the finely particulate inorganic solid dispersely distributed in an aqueous medium and at least one kind of dispersion.

Abstract: The invention relates to the use of an emulsion polymer in aqueous cosmetic compounds. The emulsion polymer is obtained by emulsion polymerization of a monomer mixture (A) containing 50-100 wt.%, in relation to the monomer mixture, C1-C18 alkyl(meth)acrylates, vinylesters, vinyl aromatics or their mixtures, in the presence of a polymer (B). Said polymer (B) is composed of b1) 5-50 wt.% monomers with at least one ionic group, or group that can be converted to an ionic group, b2) 0-95 wt.% C1-C18 alkyl(meth)acrylates, vinylesters, vinyl aromatics or their mixtures, and b3) 0-50 wt.% other monomers. The glass transition temperature of the polymers obtained from monomer mixture (A) is lower than or equal to the glass transition temperature of polymer (B).
