CATIONIC, AMINO-FUNCTIONAL, ADHESION-PROMOTING POLYMER FOR CURABLE INKS AND OTHER PLASTIC FILM COATINGS, AND PLASTIC FILM COMPRISING SUCH POLYMER

摘要

A cationically stabilizable amino-functional polymer having a number-averagemolecular weight of 3000, exists in the presence of water as a solution orstable emulsion only when the pH is = 8. Upon drying the polymer containsethylenically unsaturated moieties selected from the group consisting ofacrylic, methacrylic, and enamine. The polymer is useful to promote adhesionof curable inks and other coatings for plastic film. The invention furtherrelates to a plastic film comprising such polymer.
