Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a print medium suitable for forming a painterly printed matter, particularly a painterly printed matter using an aqueous ink such as an inkjet method.

[0002]

[Prior art]

 For example, Japanese Patent Application Laid-Open No. 49-95709 discloses a technique for reproducing a painting called a masterpiece or for obtaining a printed matter in which a portrait is reproduced based on a photographic negative film. In this technology, a water-repellent layer made of water-proof paper is provided on one side of a water-repellent paper, a paste layer is provided on it to create a mount, and the paste layer is gravure-printed on the paste layer. After printing a picture pattern layer such as a picture by offset printing, letterpress printing, etc., covering it with a synthetic resin layer, immersing this in water, a part consisting of paper and water-resistant layer, and a glue layer , The part including the pattern layer and the synthetic resin layer is separated, and the part (printed body) including the separated pattern layer is attached to the canvas. By such an operation, the unevenness of the canvas is expressed through the glue layer, the picture pattern layer and the synthetic resin layer, and a printed matter in which the printed picture pattern looks like drawn on the canvas is obtained. Further, as another example, there is a method disclosed in Japanese Patent Application Laid-Open No. 01-118500. In this method, a plastic support plate is prepared, and the surface of the plate is subjected to appropriate pretreatment so that the printed material that will be formed later can be peeled off, and then the original painting is used as a basis for silk screen printing or lithographic printing. This is a method in which a printed material obtained by performing color printing is dried on a support plate, and then pressure and heat are applied in a state where the printed material is brought into close contact with the canvas to transfer the printed material from the support plate to the canvas side.

In these methods, a canvas is used as a base material, a print body (layer) on which a picture pattern is printed is laminated on the canvas, and a canvas-like unevenness is formed on the picture pattern to express a painterly touch. The printed matter obtained is characterized in that it is very different from the ordinary printed matter in which a picture pattern is printed on a flat paper surface.

[0004]

[Problems to be solved by the device]

 However, the above conventional method has the following drawbacks. For example, in the case of the method obtained by the method described in JP-A-49-95709, since the printed material is laminated on the canvas by gluing, the printed material may be deteriorated due to aging of the adhesive layer, deterioration due to heat, etc. Sometimes it fell off the canvas. Further, in the method described in Japanese Patent Application Laid-Open No. 01-118500, the printed matter is transferred to the canvas side by applying pressure and heat in a state where the printed matter is brought into close contact with the canvas. In some cases, the printed matter was deformed and the transfer could not be performed well.

An object of the present invention is to provide a printing medium capable of forming a painterly printed matter by direct printing.

[0006]

[Means for Solving the Problems]

 The printing medium of the present invention, which solves the above-mentioned drawbacks in the prior art, has a canvas material provided with a layer having oil resistance and water resistance on a fabric having a predetermined weave, and an ink receiving layer. The receptive layer is laminated on the layer having oil resistance and water resistance.

The canvas used for the printing medium of the present invention is not particularly limited as long as it has a texture that can provide a canvas with a desired touch, and for example, it is widely used as a canvas. Can be used. Specifically, a sheet in which threads made of hemp, cotton, etc. are woven into a desired texture is provided with an oil- and water-resistant layer made of glue, casein, lead white, etc. on a predetermined surface. be able to. In the present invention, the canvas fabric is not limited to that made of hemp and cotton, since it has a certain texture and can exhibit good bondability with a layer having oil resistance and water resistance. I wish I had it. Further, the layer having oil resistance and water resistance is not limited to the above materials, and may be any layer as long as good bondability with the woven fabric and the ink receiving layer can be obtained.

The ink receiving layer laminated on the layer having oil resistance and water resistance may be any layer that has absorbability, penetrability and retention of the water-based ink and can be printed with the water-based ink. . The ink receiving layer can be composed of a hydrophilic polymer such as polyvinyl alcohol, polyvinylpyrrolidone, cellulose derivative polyester, sodium polyacrylate, polyamide, polyacrylamide, polyurethane and melamine resin. One of these hydrophilic polymers can be used alone, or two or more of these can be used in combination.

【Example】

 FIG. 1 is a diagram schematically showing the structure of a printing medium of the present invention as an enlarged partial sectional view. Reference numeral 1 is a canvas portion having the same structure as a conventional oil painting canvas. An insulating layer 3 obtained by applying glue or caseinin is applied onto a woven fabric 2 made of hemp or cotton, and lead white is applied. The layer 4 thus obtained is provided. In this example, the layer having oil resistance and water resistance is composed of an insulating layer 3 (oil resistant layer) and a layer 4 (water resistant layer). The surface of the woven fabric 2 is formed with irregularities according to the texture, and these irregularities are displayed even in the outermost ink receiving layer. The thickness of each layer forming the canvas can be set to the same level as a normal canvas.

In the printing medium of the present invention, the ink receiving layer 5 is formed on the canvas. The ink receiving layer 5 is a layer that has absorbability of the water-based ink, is easily penetrated by the water-based ink, and retains the water-based ink and can be printed with the water-based ink. It can be configured as a coating layer of molecules. The thickness of the ink receiving layer 5 can be, for example, in the range of 5 to 20 μm, the upper limit thereof is preferably 15 μm, and the lower limit thereof is preferably 5 μm.

The printing medium thus configured is fixed to a wooden frame, a plate, a mount, etc., and a pressure pulse method (including a bubble jet method), an electrostatic pulse method, an electrostatic ejection electrostatic deflection method, a pressure ejection method is used. Printing is performed by directly applying the water-based ink to the ink receiving layer 5 of the printing medium by a printing method using an electrostatic deflection method or an inkjet method of any other method, and printing is performed, resulting in a painting-like printed matter with canvas irregularities. Can be obtained.

[0012]

[Effect of device]

 As is clear from the above description, the printing medium of the present invention has a structure in which an ink receiving layer is provided on the surface of a canvas material having a texture of a predetermined touch, so that it can be directly printed by an ink jet printer or the like. It is possible to obtain a painting-like printed matter by printing the above-mentioned pattern, which eliminates the need for operations such as sticking or transferring a printed material as in the conventional method.
