摘要： Embodiments of the present disclosure provide a coated film structure including a substrate layer, an overcoat layer, and at least one intermediate layer disposed between the substrate layer and the overcoat layer. The substrate layer includes a polymer film substrate, the overcoat layer includes an acid-functional copolymer, and the at least one intermediate layer includes aluminum oxide. The coated film structure has an oxygen transmission rate of less than about 3.00 cm3/m2/day at 50% relative humidity and 23° C. as measured in accordance with ASTM D3985. Further, the coated film structure has a water vapor transmission rate of less than 2.50 g/m2/day at 90% relative humidity and 37.8° C. as measured in accordance with ASTM E-398.

摘要： Electrophotographic printing techniques offer excellent image quality, but image adhesion to a desired substrate may be problematic in many instances. Primer coatings for improving image adhesion to a substrate may be formed from primer compositions comprising a fluid and an amine-functionalized copolymer dispersed in the fluid as an emulsion, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer. The fluid may be aqueous or organic. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group. The at least one amine group comprises a side chain of the amine-functionalized copolymer.
