A cationically stabilizable amino-functional polymer having a number-average molecular weight of >3000, exists in the presence of water as a solution or stable emulsion only when the pH is ≦8. Upon drying the polymer contains ethenically unsaturated moieties selected from the group consisting of acrylic, methacrylic, and enamine. The polymer is useful to promote adhesion of curable inks and other coatings for plastic film. The invention further relates to a plastic film comprising such polymer.
一种可阳离子稳定的氨基官能团聚合物,其平均分子量大于 3000,只有在 pH 值为 8 时才会以溶液或稳定乳液的形式存在于水中。干燥后的聚合物含有选自丙烯酸、甲基丙烯酸和烯胺类的乙烯不饱和分子。该聚合物可促进固化油墨和其他塑料薄膜涂层的附着力。本发明还涉及一种含有这种聚合物的塑料薄膜。
