Abstract:
1. A polymer film comprising: a) a polymeric substrate having a first side and a second side; b) a back-side coating on the first side of the substrate, the back-side coating formed from at least an ionomer, an acrylic emulsion, and at least one inorganic material, said inorganic material comprising a majority of particles having a mean largest dimension in the range of 0.2 μm to 25 μm; and c) a polymeric surface layer in contact with the second side of the polymeric substrate, wherein the polymeric surface layer is a printable front-side layer, and wherein the back-side coating includes a primer layer positioned in contact with the second side of the polymeric substrate, wherein the printable front-side layer comprises at least one of a cationic polymer, a second cross-linking agent, a cross-linking catalyst, an adhesion promoter, and a second inorganic material, said second inorganic material comprising particles having a mean largest dimension ranging from about 2.0 μm to about 5.0 μm.
