摘要:
(Meth)acrylic resin compositions and films are disclosed herein and comprise two or more kinds of polymer, particularly, a carboxyl group-containing (meth)acrylic polymer and a piperidinyl group-containing polymer. The carboxyl groups and piperidinyl groups form acid-base ionic bonds, so affinity between the two polymers is improved and the film exhibits good toughness. The films disclosed herein may be used as receptor sheets for printing processes such as electrostatic toner printing and inkjet printing.
