Abstract

(57) [Abstract] [Purpose] To provide an ink jet printer paper which is inexpensive, has no curling property, can be used outdoors where water leaks, and has various advantages. [Structure] A synthetic resin film 10 having a thin Japanese paper 30 adhered to the surface thereof.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sheet used in an ink jet printer.

[0002]

[Prior art]

 Since the ink on the above-mentioned paper easily bleeds with conventional paper, a special water-soluble resin is coated on the paper surface in order to realize appropriate absorption of ink and resistance to bleeding around it. The thickness of the coating layer must be at least 15 microns in order to absorb the ink, which is expensive and has the drawback that the paper surface curls greatly when absorbing ink. It is also used outdoors when water leaks. There were drawbacks such as not being able to.

[0003]

[Problems to be solved by the device]

 The present invention provides an ink jet printer paper which is inexpensive, does not curl, can be used outdoors where water leaks, and has various advantages.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the ink jet printer paper of the present invention comprises a synthetic resin film 10 having a thin Japanese paper 30 adhered to the surface thereof as shown in the figure.

In order to achieve the above-mentioned object, the ink jet printer paper of the present invention comprises a synthetic resin film 10 having a thin paper 30 adhered to the front surface and an adhesive 40 applied to the back surface, as shown in the figure. The adhesive layer 40 and a release paper 50 that can be peeled off are adhered to the front surface, and a film 60 having a matting agent 70 applied to the back surface is formed.

In the present invention, there are three methods for adhering the thin Japanese paper 30 and the synthetic resin film 10. That is, an adhesive agent or an adhesive agent is applied between the thin paper 30 and the synthetic resin film 10, and a thermoplastic film is placed between the thin paper 30 and the synthetic resin film 10 for heat fusion. It is conceivable to heat-bond the synthetic resin film 10 and the synthetic resin film 10 together. The thin Japanese paper 30 preferably has a basis weight of 50 g / m ^{2 to} 20 g / m ² . If it is 50 g / m ² or more, the running property may be deteriorated, and if it is 20 g / m ² or less, the ink absorption may be deteriorated. Further, the synthetic resin film 10 is preferably heat resistant and non-hygroscopic and has a thickness of 75 micron or less. If it is 75 microns or more, the running property may be deteriorated. As the release paper 50, paper coated with silicone resin or the like is used. The matting agent 70 applied to the back surface of the paper to prevent double feeding during printing preferably has a particle size in the range of 0.007 to 20 microns.

[0007]

Embodiment 1 An embodiment of the present invention is shown in FIG. In the ink jet printer paper of this example, a Washi paper 30 having a basis weight of 20 g / m ² is adhered to the surface of a synthetic resin film 10 having a thickness of 15 μm through a thermoplastic resin film 20 having a thickness of 20 μm. In addition, the back surface is coated with a matting agent 70 made of silica having a particle size of 0.007 to 20 microns.

[0008]

Embodiment 2 Another embodiment of the present invention is shown in FIG. The ink jet printer paper of this example is used by adhering to a product for use as a label for a product, and a basis weight of 20 g / g is applied through a 20-micron-thick thermoplastic resin film 20 heat-fused on the surface. While adhering the m ² Japanese paper 30 and the 15-micron-thick synthetic resin film 10 with the adhesive 40 applied on the back side, the adhesive layer 40 and the release paper 50 that is releasably attached to the front side are attached to the back side. A film 60 coated with a matting agent 70 made of silica having a particle size in the range of 0.007 to 20 microns. This paper is used after being printed with an ink jet printer, after which the release paper 50 is adhered to the front surface and the film 60 coated with the matting agent 70 on the back surface is removed.

[0009]

[Effect of device]

 Therefore, when the ink jet printer paper of the present invention as shown in Examples 1 and 2 is printed by the ink jet printer, the ink is deposited on the Japanese paper on the surface of the paper, but the Japanese paper absorbs the ink appropriately. There is no bleeding. Also, even if the ink is absorbed, the paper surface does not greatly curl. Furthermore, even if this paper is used outdoors, the printing will not bleed or disappear due to water. In addition, Japanese paper can be used as a very thin one, giving the overall paper flexibility and the advantage that it can be manufactured at low cost.
