Abstract
The present invention relates to a self adhesive ink jet printable polymer film. The film comprises a polymeric resin and a low surface energy additive that is in a substantially free form. The polymeric resin can be PVC, and the low surface energy additive can be silicone. The film comprising the low surface energy additive exhibits high print resolution and substantially uniform printing quality even after the print surface of the film has been in contact with a back surface of a release liner comprising residual silicone.
Claims47
A self adhesive print film comprising:
- a polymeric print layer having an upper surface and a lower surface, the polymeric print layer adapted to receive a print media on the upper surface;
- and
- an adhesive layer disposed on the lower surface of the polymeric print layer;
- wherein the polymeric print layer comprises a low surface energy additive distributed in the polymer layer or disposed about the surface of the polymer layer.
A method for improving the print resolution of a self adhesive film provided in a roll form, the method comprising:
- providing a polymer print film layer having an upper surface for receiving a print media thereon, and a lower surface opposite the upper surface;
- providing an adhesive film layer on the lower surface of the polymer print film layer;
- and
- providing a release liner having an upper surface comprising a release coating thereon, and a lower surface, the lower surface of the release liner contacting the upper surface of the polymer print film layer when the self adhesive film is wound about itself into a roll;
- wherein the polymer print film layer comprises a low surface energy additive distributed in the polymer layer or disposed about the surface of the polymer layer.
