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.
