One way vision film for ink jet printing, printing film, and method for producing them
Abstract:
A one-way vision film includes a white film base material; a shrinkable color tone layer on one side of the base material; and a self-adsorptive foamed layer on the base material opposite to the shrinkable color tone layer. The one-way vision film is perforated with through-holes. The self-adsorptive foamed layer has an adhesive function attachable to a surface onto which the film is attached and is printable. Since the printing ink is deposited to the bottoms of the open pores while not closing the openings of the open pores, open pores exposed to the surface of the foamed layer function like suction cups adhering onto a smooth surface. Accordingly, there is no need for forming ink-receptive and pressure-sensitive layers, unlike a conventional film, so the film can have a low cost, three-layer structure. The one-way vision and printed film is easily attachable onto a smooth and transparent substrate like glass.
