DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating member for covering (laminating) an image surface of a print obtained by forming an image on a recording medium with a transparent film layer, and a print member using the same. The present invention relates to a laminating method and a print having an image surface on which a transparent film layer is laminated.

[0002]

2. Description of the Related Art Printed materials, such as ink jet, offset, gravure, and electrophotographic images, are subjected to lamination processing on the surface on which the image is formed (image surface), so that the image is robust such as light resistance, water resistance, and friction resistance. It is widely known that the image quality is improved by improving the glossiness and smoothness of the image surface and the maximum density of the image.

[0003] In particular, an ink jet recording apparatus adopts a method of printing a dye dissolved in water on a recording medium having high water absorbability due to a restriction on a printing method that ink is ejected from a fine discharge port. Are widely spread. Printed matter formed by an ink jet recording method using an aqueous ink containing a water-soluble dye generally has poor weather resistance in many cases, and a lamination treatment is effective for increasing the robustness of the image. .

[0004]

The lamination process involves
After the transparent resin layer supported by the heat-resistant base material is pressed against the image surface of the print, the heat-resistant base material is peeled from the transparent resin layer, and the transparent resin layer is left on the image surface to obtain a completed print. And a method of obtaining a completed print by leaving the heat-resistant substrate on the image surface without peeling off.

[0005] When the heat-resistant substrate is not peeled off, the properties of the heat-resistant substrate itself are reflected on the print. For heat resistant substrates,
A sheet of polyethylene phthalate or the like is used and has sufficient heat resistance, but generally has a haze. Therefore, if the heat-resistant substrate is left on the image surface, the print tends to have a low image density. On the other hand, when the heat-resistant base material is peeled off and not left on the image surface, the properties of the remaining transparent film layer are reflected on the print. When the transparent film layer is formed of a thermoplastic resin having better transparency, glossiness, smoothness, etc. than the material constituting the heat-resistant base material, the heat resistance is usually lower than the heat-resistant base material, A print having a high image density can be obtained.

However, in a print having a transparent film layer made of a thermoplastic resin on the image surface, when the print is left in an environment of high temperature, the shape of the porous particles on the image surface or the aggregate The transparent film layer can follow irregularities due to irregularities, irregularities in the formation of the substrate part of the print, etc.
As a result, the smoothness of the transparent film layer may decrease with time in a high-temperature environment, and the gloss may be lost.

[0007] Therefore, in the laminating process of a print, a technique for achieving both image quality and robustness has been required. An object of the present invention is to provide a member for laminating a printed matter, which can impart sufficient rigidity while maintaining the effect of improving image quality, a lamination process using the same, and a laminated printed material. It is in.

FIG. 1 is a sectional view showing an example of a laminate film according to the present invention. This laminate film is formed on a heat-resistant base material 1a by a first layer 1b (hereinafter, referred to as a surface protective layer), which becomes a surface protective layer when transferred to the image surface of the print, and an adhesive layer to the image surface. Second layer 1 to be
c (hereinafter referred to as an adhesive layer) is laminated in this order. As the heat-resistant base material, when the adhesive layer was thermocompression-bonded to the image surface of the print, the form could be stably maintained under the heat and pressure conditions, and a transparent film layer was formed on the image surface of the print Any material can be used as long as it can be easily peeled off at the stage. For example, a film or sheet made of a material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyphenylene sulfide (PPS), or polyether sulfone (PES) is used.
