Title:

ONE WAY VISION FILM FOR INK JET PRINTING, PRINTING FILM, AND METHOD FOR PRODUCING THEM

Document Type and Number:

WIPO Patent Application WO/2008/078825

Kind Code:

A1

Abstract:

This invention provides a one way vision film comprises a white film as a base material (2), a shrinkable color tone layer (1) stacked on one side of the base material (2), and a self-adsorptive foaming layer (3) provided on the base material (2) on its side remote from the shrinkable color tone layer (1), the whole one way vision film being perforated (7). The self-adsorptive foaming layer (3) functions as a face having the function of adhesion to the face to which a film is to be applied. Further, an image can be printed onto the surface of the self-adsorptive foaming layer (3). A printing ink is deposited onto the bottom of cells without clogging the openings of open cells (3a). Accordingly, a number of the open cells (3a) present on the surface of the foaming layer (3) functions as in a suction disk, and the ink is adsorbed onto a smooth face. According to the above constitution, unlike the prior art technique, the provision of an ink receptive layer and a pressure-sensitive adhesive layer are unnecessary, and a three-layer structure can be adopted. Thus, the one way vision film can be produced at low cost. Therefore, a one way vision film and a printing film, which can easily be applied to a smooth and transparent base material as in a window glass from its inside, can be provided.
