AI Technical Summary

Problems solved by technology

It is easy to peel off, and the through-hole part is prone to fouling and difficult to clean because of the unevenness
Also in this case, the thin resin film containing the dielectric layer to which the image is transferred is designed to cover the through hole, which also impairs the transparency of the through hole.
Also, the image itself is not lightfast in direct sunlight
In order to improve the light fastness of the image, there is no choice but to laminate an ultraviolet shielding film on the entire surface, which not only further deteriorates the sense of transparency but also increases the production cost

Embodiment 1

[0042] On a biaxially stretched transparent polyester film (Teijin Tetron Film S6, trade name, manufactured by Teijin Co., Ltd.) with a thickness of 50 micrometers, a tetrafluororesin coating (DUFLON 4F FreshWhite, trade name, manufactured by Nippon Paint Co., Ltd.) was first laminated to 15 Micron thickness and cured to form a white coating layer as the first layer. Then, a tetrafluororesin paint (fluoroethylene-vinyl ether copolymer-based paint) (DUFLON 4F Fresh White, trade name, manufactured by Nippon Paint Co., Ltd.) was laminated to a thickness of 15 μm and cured to form a second layer Blackout color coating. Thereafter, a pressure-sensitive adhesive layer was laminated on the reverse side of the film and a heat-resistant release layer was laminated thereon. Circular through-holes with a diameter of 1.5 mm were regularly perforated on the entire surface of the film with a porosity of 50%. Thus, a unidirectional see-through decorative film is prepared. A sublimation dy...

Embodiment 2

[0044] On a 50 micron thick biaxially stretched transparent polyester film (Teijin Tetron Film S6, trade name, Teijin Co., Ltd.), first laminate a single-liquid thermosetting polyester resin clear coating (SENOKOYL, trade name, manufactured by Cashew Corporation). system) to a thickness of 30 microns and cured to form a clear coating layer as the first layer. Then follow the same procedure as in Example 1 using the same "DUFLON 4F Fresh White" layer combination as the 2nd layer of white coating. Then, follow the same procedure as in Example 1, using the "DUFLON 4F FreshBlack" layer as the 3rd layer of opaque color coating. Thereafter, an adhesive layer was laminated on the opposite surface of the film, and a heat-resistant barrier layer was bonded thereon. Through-holes exactly the same as those in Example 1 were drilled on the entire surface of the film to prepare a decorative film. On the black paint-coated side of this decorative film, thermal transfer was performed in th...

Embodiment 3

[0046] On the biaxially stretched transparent polyester film (Teijin Tetron Film S6, trade name, manufactured by Teijin Co., Ltd.) with a thickness of 50 μm, first laminate two-liquid thermosetting polyacrylic polyurethane clear coatings (Acrylic Urethane Resin Vanish 7987, trade name name, manufactured by Isamu Paint) to a thickness of 30 micrometers and cured to form a clear coating layer as the first layer. Then follow the same procedure as in Example 1 using the same "DUFLON 4F Fresh White" layer combination as the 2nd layer of white coating. Then, follow the same procedure as in Example 1, using the "DUFLON 4F Fresh Black" layer as the 3rd layer of opaque color coating. Thereafter, an adhesive layer was laminated on the opposite surface of the film, and a heat-resistant barrier layer was bonded thereon. Through-holes exactly the same as those in Example 1 were drilled on the entire surface of the film to produce a decorative film. On the black paint-coated side of this ...

Abstract

A unidirectionally penetrable ornamental film comprising a laminate having a transparent resin film 3 in which a sublimable dye is diffusible, a white coating layer 2 on the transparent resin film 3, a light-shielding color coating layer 1 on the white coating layer 2, a pressure sensitive adhesive layer 4 on a surface of the transparent resin film 3 opposite to a surface on which the white coating layer 2 is provided, and a separator 5 on the pressure sensitive adhesive layer 5, in which throughholes having an area of 10 mm2 or less are formed in an opening ratio in the range of 30 to 70% and resins that constitute the white coating layer 2 and the light-shielding color coating layer 1 have no affinity for the sublimable dye. Also disclosed is a unidirectionally penetrable ornamental film, comprising a dye image on the ornamental film, the image being obtained by superimposing a transfer paper having recorded thereon an image with an ink containing a sublimable dye, contacting the transfer paper with the ornamental film and heating the transfer paper to pass the sublimable dye through the light-shielding color coating layer 1 and the white coating layer 2 to thereby transfer dye the transparent resin film in a high density.

Description

technical field [0001] The present invention relates to a one-way see-through decorative film attached to a glass window or a transparent acrylic plate or the like. Background technique [0002] A one-way see-through film called Oneway Vision has been known so far. This involves painting one side of the film in an opaque color such as black and the other side in white, laminating a layer of pressure sensitive adhesive and a release layer on the opaque side. And the entire surface of the film is drilled with many circular through holes with a diameter of about 1-2 mm, and the opening ratio is about 30-70%. When in use, the film is peeled off to remove the isolation layer and attached to the glass windows of the house. When viewing the outside through the film from inside the house during the day, the bright outside world can be seen through the many through-holes arranged in the shading finish surface, so it is possible to see through the outside with a feeling that the vie...
