摘要：
The present invention provides for the use of film-forming aqueous formulations comprising in dispersed form at least one crosslinked copolymer P for coating shaped mineral articles and for a method of coating shaped mineral articles, said copolymer P comprising in copolymerized form a) from 80 to 99.89% by weight of at least one monomer selected from esters of acrylic acid with C1-C12-alkanols, esters of methacrylic acid with C1-C8-alkanols, and monovinylaromatics, b) from 0.1 to 19.99% by weight of at least one monomer different from a), and c) from 0.01 to 1.9% by weight of at least one crosslinking monomer selected from esters of acrylic or methacrylic acid with linear or branched C3-C6-alkenols, cyclic C5-C7-alkenols and polycyclic C2-C12-alkenols.
