Zusammenfassung: | The present invention relates to use of an aqueous polymer composition containing a water-soluble or water-dispersible polymer P made of polymerized ethylenically unsaturated monomers M comprising * 30 to 90 wt.-%, based on the total weight of monomers M, of at least one monomer M1 selected from C1-C12-alkyl esters of monoethylenically 0unsaturated carboxylic acids, C6-C10-cycloalkyl esters of monoethylenically unsaturated carboxylic acids and monovinylaromatic hydrocarbon monomers, * 5 to 30 wt.-%, based on the total weight of monomers M, of at least one monomer M2 selected from monoethylenically unsaturated monomers containing at least one acid group, and * 5 to 40 wt.-%, based on the total weight of monomers M, of at least one monomer M3 different from M2 which has a reactive functional group beingcapable of being crosslinked,wherein the total weight of monomers M1, M2 and M3 corresponds to at least 90% of 0the total weight of monomers M; wherein the monomers M are selected such that the theoretical glass transition temperature according to Fox (Tgt) of the polymer P is at most 80°C; andwherein the polymer P is dissolved or dispersed in an aqueous phase such that the acid groups of the polymer P are totally or partially neutralized; as a staining composition for porous materials.The present invention also relates to an aqueous polymer composition containing saidwater-soluble or water-dispersible polymer P made of polymerized ethylenically unsaturated monomers M and a crosslinking agent.
La présente invention concerne l'utilisation d'une composition polymère aqueuse contenant un polymère P hydrosoluble ou hydrodispersable constitué de monomères M polymérisés, à insaturation éthylénique, comprenant * 30 à 90 % en poids, sur la base du poids total des monomères M, d'au moins un monomère M1 choisi parmi des esters alkyliques en C1-C12 d'acides carboxyliques à insaturation monoéthylénique, des esters cycloalkyliques en C6-C10 d'acides carboyliques à insaturation monoéthylénique, et des monomères hydrocarbonés monovinylaromatiques, * 5 à 30 % en poids, sur la base du poids total des monomères M, d'au moins un monomère M2 choisi parmi les monomères à insaturation monoéthylénique contenant au moins un groupe acide, et * 5 à 40 % en poids, sur la base du poids total des monomères M, d'au moins un monomère M3 différent de M2 qui possède un groupe fonctionnel réactif pouvant être réticulé, le poids total des monomères M1, M2 et M3 correspondant à au moins 90 % du |
