PROBLEM TO BE SOLVED: To prevent separation between overlapping laminated materials with images formed thereon.SOLUTION: An image is formed on a material using ink containing an organic solvent. After the ink is fixed, the material is laminated. A surface of the laminated material to be overlapped is modified, and the material is overlapped on another laminated material.

Description

  The present invention relates to an overlaying method in which an image formed product formed using an ink containing an organic solvent is laminated and overlaid on the laminate, and a method for producing a recorded material overlaid on the laminate.

  2. Description of the Related Art Conventionally, one image is completed by pasting together a plurality of image formed products on which images are formed using an inkjet recording apparatus or the like. For example, for outdoor signs, create multiple image formations that form a part of a large image on a recording medium that uses PVC on the image forming surface and an adhesive layer on the back surface. A single image is completed by pasting objects together. In this case, generally, the second image formed product is overlaid on a part of the first image formed product. Specifically, a part of the first image formed product and a part of the second image formed product have images of the same part on the large image, and when the parts are overlapped and pasted, It is done that continuity is maintained.

On the other hand, laminating to an image formed product is performed for the purpose of protecting the image formed product on which an image is formed using an inkjet recording apparatus or the like.
For example, in Patent Document 1, a surface layer, an intermediate layer, and a permeation layer are sequentially laminated on a heat-resistant substrate, the surface layer and the intermediate layer are thermosoftening, and the glass transition temperature of the intermediate layer is Disclosed is a laminate film having a lower temperature than the glass transition temperature of the surface layer and the permeation layer being heat-meltable.

  In addition, for example, Patent Document 2 discloses a layer on the opposite side of the image adhesion surface of the laminate film in which the image adhesion surface and the image recording surface of the laminate film are superposed either at the same time as image formation or after image recording. Discloses a laminating method in which heat and pressure treatment is performed at a temperature equal to or higher than the heat deformation temperature of the thermoplastic resin contained in the resin.

  However, as a result of intensive studies by the inventor, the present inventor has found that the following new problem may occur. When an image is formed on a recording medium using PVC on the image forming surface (front surface) and an adhesive layer is provided on the back surface, and these are directly laminated, the image forming surface of the recording medium on which the image has been formed is not peeled off. When laminating and laminating and laminating the laminated image formed product, it may be peeled off. In particular, depending on the type of ink used for image formation, such a phenomenon becomes significant.

  Further, as a result of intensive studies by the present inventors, peeling when laminating a laminated image formed product has a sufficient adhesive force when the adhesive layer is initially attached to the back surface of the recording medium, but for a predetermined time. Later, it was found that this adhesive force was caused by suddenly weakening. It has also been found that the same phenomenon occurs even if the film material used for lamination is changed. In addition, the decrease in adhesive strength was remarkable in the portion where a lot of ink was used during image formation, and there was almost no decrease in the adhesive strength in the portion where ink was hardly used during image formation. . Further, the back surface of the film used for the lamination used by the present inventors is provided with an adhesive layer similar to the adhesive layer used on the back surface of the recording medium. And did not peel off. In other words, when the amount of ink used is large, the adhesive force between the recording medium adhesive surface and the laminate film surface decreases, but the recording medium adhesive surface and the laminate film adhesive surface The adhesive strength with the surface of the recording medium does not decrease.

  Further, the inventor has further studied diligently, and the decrease in the adhesive force between the adhesive surface of the recording medium and the surface of the laminate film is caused by the fact that the solvent of the ink when the image is formed oozes out on the surface of the laminate film. It was found that the adhesive force of the adhesive layer of the recording medium was reduced. In addition, although the adhesive force between the adhesive surface of the recording medium and the surface of the laminate film is reduced, it is not clear why the adhesive surface of the recording medium and the adhesive force between the adhesive surface of the laminate film and the surface of the recording medium are not reduced. . However, the adhesive force of the adhesive surface of the recording medium and the adhesive surface of the laminate film is originally stronger against the surface of the recording medium than to the surface of the laminate film, and the laminate film is more surface than the recording medium. It is conceivable that the solvent can easily ooze out.

  Therefore, the present invention has been made in order to find a new problem that has not been manifested so far, and to solve the problem, and even when the laminated image formation is overlapped, it does not cause peeling. An object is to provide a pasting method.

  The present invention for solving the above problems is a method of laminating and laminating on an image formed product formed using an ink containing an organic solvent, and laminating the laminate on the laminate, using the ink An image forming step for forming the image formed product, a laminating step for laminating the image formed product after fixing the ink, and a surface modifying step for modifying the surface of the portion to be overlaid on the laminate And a superposition step of performing superposition on the surface.

  ADVANTAGE OF THE INVENTION According to this invention, even when it laminates | stacks the laminated | stacked image formation thing, it can provide the overlaying method which does not produce peeling, and a recorded matter.

It is a flowchart which shows preferable embodiment of the overlapping bonding method of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a flowchart showing a preferred embodiment of the method for overlaying according to the present invention.
In addition, although this embodiment is embodiment about the form which forms an image using the ink containing an organic solvent with an inkjet recording device, it is not limited to this.
First, in step S110, an image is formed on a recording medium using PVC on the image forming surface with an ink containing an organic solvent using an ink jet recording apparatus.

Next, in step S120, it is determined whether the ink of the image formed in step S110 is fixed. After the ink is fixed, the process proceeds to step S130. The fixing of the ink can be determined based on whether the coloring material of the ink is fixed on the recording medium, for example, when the coloring material is not touched when the image forming portion is touched by hand.
Next, in step S130, the image formed material in which the ink color material is fixed on the recording medium is laminated.

  Next, in step S140, the surface modification of the portion to be overlaid on the laminate is performed. Specifically, the adhesive force is improved by scratching this portion and making irregularities on the surface of the laminate film. In this embodiment, the surface modification is performed by scratching with a file, but the present invention is not limited to this. For example, surface modification of this part can also be performed using corona discharge or the like.

  Finally, in step S150, the image forming product, which has been subjected to surface modification of the portion to be overlaid on the laminate in step S140, is overlaid on a desired location and pasted to complete the present overlying method.

  In the following examples, a color printer W-64s (manufactured by Seiko I Infotech) was used as the ink jet recording apparatus, and HAPs Free IX ink, which is a genuine ink of the color printer W-64s, was used as the ink. In addition, IJ180 (manufactured by Sumitomo 3M) was used as a recording medium, and IJ4114 (manufactured by Sumitomo 3M) was used as a laminate film.

  Using the recording apparatus color printer W-64s, two solid images having a recording duty of 300% in total in cyan, magenta, yellow, and black were recorded on IJ180 with the IX ink. Next, the two recorded materials were laminated using IJ4114 24 hours after recording.

  Next, for one of the two recorded materials, the laminate surface is scratched with a file, and the IJ180 adhesive surface cut to 25 mm × 100 mm is attached to the scratched portion of the laminated recorded material. (Example 1).

  On the other hand, the remaining one of the two recorded materials was directly laminated using IJ4114 without modifying the laminate surface. Thereafter, an adhesive surface of IJ180 cut to 25 mm × 100 mm was attached to the laminated recorded matter (Comparative Example 1).

  About the said comparative example 1, when this was peeled by hand 24 hours after sticking cut IJ180, the adhesive force obviously fell. On the other hand, in Example 1 above, when the cut IJ180 was pasted and it was peeled off by hand 24 hours later, the decrease in adhesive strength as in Comparative Example 1 was not observed.

  The overlaying method of the present invention can be used in any case of laminating on an image-formed product formed using an ink containing an organic solvent and overlaying on the laminate.
