    Abstract: Surprisingly aqueous preparations containing a copolymer P as completely or largely cross linked constituent comprising methacrylic acid alkyl esters, in which the bulk of methyl methacrylate monomer varies give coatings of gloss with increased stability over time. The coatings show good adhesions to mineral substrates and guarantee good protection against efflorescence. The use of an aqueous film forming preparation, for coating a mineral molded body, containing at least one copolymer P as film forming component dispersed in the preparation and ethylenically unsaturated monomers M is new. The monomer M comprises (wt. %): (i) 70-99 of at least one methacrylic acid ester with a 1-10C alkanol and (ii) 0.1-30 of at least one of different ethylenically unsaturated monomers, in which at least 50 wt. % of monomer M comprises methacrylic acid methyl ester, and at most 1 wt. % of monomer M contains two or more ethylenically unsaturated double bonds. Independent claims are included for: (1) A process for coating a mineral molded body with at least one aqueous film forming preparation; (2) a mineral molded body.

    Abstract: The invention relates to the application of microcapsules I with one or more lipophilic substances as core material. Said lipophilic substances have a solid/liquid phase transition at a temperature ranging from -20 to 120 ~C and a polymer which is used as a shell and can be obtained by means of radical polymerization of a monomer mixture containing 30 to 100 wt.%, referring to the total weight of the monomers, one or more C1-C24-alkyl esters of the acrylic acid and/or methylacrylic acid (monomer I), 0 to 80 wt.%, referring to the total weight of the monomers, one bi- or polyfuntional monomer (monomer II) which is insoluble or poorly soluble in water, and 0 to 40 wt.%, referring to the total weight of the monomers, and other monomers (monomer III). The microcapsules can be used as latent heat accumulators. The invention also relates to novel microcapsules Ia, spray-dried microcapsules Ia', methods for the production thereof, and to shaped bodies and coating masses containing said microcapsules.
