    • A curable aqueous polymer dispersion is prepared by: I) reacting a (meth)acrylate polymer A) that carries ethylenically unsaturated groups and functional groups capable of a condensation or addition reaction, with at least one compound B) which Ia) carries at least one functional group that is complementary to the functional groups of the copolymer A) that are capable of undergoing a condensation or addition reaction, and additionally at least one ionogenic, ionic group or a combination thereof, or which Ib) carries at least one functional groups that is complementary to the functional groups of the copolymer A) that are capable of condensation or addition reaction and is capable of forming an ionogenic or ionic group in a condensation or addition reaction, to give a copolymer AI) which carriers ethylenically unsaturated groups and ionogenic groups, ionic groups or a combination thereof, II) with the proviso that when the ionogenic groups are present in compound B), converting at least some of the ionogenic groups of the copolymer AI) into ionic groups, and III) dispersing the copolymer AI) in an aqueous dispersion medium.
    • 通过以下步骤制备可固化的聚合物水分散体:I)使携带烯键式不饱和基团和能够缩合或加成反应的官能团的(甲基)丙烯酸酯聚合物A)与至少一种化合物B)反应,其中Ia)携带至少一种 与共聚物A)的官能团互补的官能团,其能够进行缩合或加成反应,另外还含有至少一种离子型离子基团或其组合,或者Ib)携带至少一个官能团, 与能够缩合或加成反应并能够在缩合或加成反应中形成离子基团的共聚物A)的官能团互补,得到载体烯键式不饱和基团和离子型基团的共聚物 ,离子基团或其组合,II),条件是当离子发生基团存在于化合物B)中时,至少将 共聚物AI中的一些离子基团)形成离子基团,和III)将共聚物AI)分散在水性分散介质中。
