Description

The present invention relates to an image display body in which an image is printed on the back surface of a transparent sheet-like substrate.

An image display body in which an image is printed on the back surface of a transparent sheet-like base material such as an acrylic plate has come to be widely used in panels for advertising / promotion of various products and contents, interior art panels, and the like. In such an image display body, not only the design of the image itself is high, but also the display form is required to enhance the design of the entire display body. For example, the back surface of the image printing layer is white. It is common practice to suppress the transparency of an image printing layer so that the colors of an image are expressed more vividly by printing. Further, depending on the type of image and the like, it is often the case that the design is improved by imparting gloss to at least a part of the image of the image display body.

As a method of imparting gloss to an image of an image display body, for example, there is one proposed in Patent Document 1. In the gloss imparting method of Patent Document 1, a clear ink made of an ultraviolet curable transparent resin is printed on the surface of a panel or the like on which an image is printed, in whole or in part, and a mirror-finished transparent polyester film is applied to the surface thereof. The clear ink is cured by irradiating it with ultraviolet rays with a high-pressure mercury lamp, and then the polyester film is peeled off. According to this method, it is said that a mirror gloss can be obtained on a portion printed with clear ink.

Japanese Unexamined Patent Publication No. 64-1-1674

However, in the gloss imparting method proposed in Patent Document 1, it is necessary to prepare an ultraviolet curable clear ink, and a step of irradiating the clear ink with ultraviolet rays with a high-pressure mercury lamp or the like is included, so that a panel or the like is included. There is a problem that it takes time and effort to manufacture the image display body. In addition, since a layer of cured clear ink is present on the surface of the image display body, when the surface of the image display body rubs against another object during use, the glossiness of the rubbed portion disappears and the display is displayed. There is a risk that the design of the entire body will deteriorate.

Therefore, it is an object of the present invention to provide an image display body capable of imparting gloss to an image in a simple process at the time of production and maintaining a stable design at the time of use.

In order to solve the above problems, the present invention covers the transparent sheet-like base material, the translucent image printing layer formed on the back surface of the sheet-like base material, and the entire back surface of the image printing layer. In an image display body provided with a white print layer formed in, the white print layer has a transparent clear print portion in a portion overlapping a predetermined portion of the image print layer, and is formed on the back surface of the white print layer. We adopted a configuration in which glossy films are stacked so as to cover at least the clear printed portion.

According to the above configuration, when manufacturing an image display body, image printing and white printing are performed on a sheet-like substrate, and a glossy film is laminated on the back surface of the white printing layer and fixed by an appropriate means. It is possible to add gloss to the image of the image display body, and since the surface is covered with a sheet-like base material, even if the surface rubs against other objects during use, there is almost no effect on the gloss. The design can be stably maintained.

Here, as the film, it is preferable to use a vapor-deposited film in which a metal is vapor-deposited on one surface of a resin-made base film. By using such a thin-film vapor film, stable metallic luster can be obtained, and by selecting an appropriate type of thin-film film, it is possible to impart designability utilizing the characteristics of the thin-film film.

Then, in particular, as the vapor-deposited film, a pattern in which grooves having a saw blade shape in cross section are arranged concentrically on one surface thereof, and the inclination angle of the saw blades of the grooves is sequentially increased from the center of the concentric circle toward the outside in the radial direction. If a lens film (see FIGS. 8A and 8B) in which at least one of the above is formed is used, the glossy portion can be seen three-dimensionally by the action of the lens film, and the design can be improved. It can be further improved.

As described above, the image display body of the present invention forms a translucent image printing layer on the back surface of a transparent sheet-like substrate, covers the entire back surface of the image printing layer, and transparent clear printing on a predetermined portion. Since a white print layer having a portion is formed and a glossy film is layered so as to cover the clear print portion, the image is glossy in a simple process without using a special material or device at the time of production. It can be imparted, and even if the surface may rub against other objects during use, the design can be stably maintained.

Sectional view taken along line IV-IV of FIG. Front view of the white print layer of FIG. Sectional drawing along the VI-VI line of FIG. Front view of the lens film of FIG. (A) is a cross-sectional view illustrating the structure of the lens film, and (b) is an enlarged cross-sectional view of a part of (a).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. This image display body is a panel for advertising / promotion that displays an image of an animated character as shown in FIG. 1, and has a laminated structure as shown in FIGS. 2 to 4. The laminated structure has a transparent sheet-like base material 1, a translucent image printing layer 2, a first white printing layer 3, and a transparent surface in order from the surface side, with the surface on which the image of the finished panel can be seen as the surface. The adhesive tape 4 (not shown in FIG. 2), the lens film 5, and the second white printing layer 6 are laminated.

In each layer of the laminated structure, each layer other than the sheet-like base material 1 is substantially entirely overlapped, and only the sheet-like base material 1 is formed so as to slightly protrude from the peripheral edge of each of the other layers. The thickness of each layer is about 10 μm for the image printing layer 2, the first white printing layer 3 and the second white printing layer 6, about 10 to 160 μm for the adhesive tape 4, and about 25 to 30 μm for the lens film 5. The sheet-shaped substrate 1 can be arbitrarily set in the range of about 50 μm to 50 mm.

When the sheet-like base material 1 is in the form of a plate having a certain thickness, a resin such as polyvinyl chloride, polyethylene terephthalate, acrylic, polycarbonate, ABS, and polystyrene can be used. Among them, the acrylic plate is particularly preferable because it has high transparency and is excellent in strength, scratch resistance, and printability.

The image printing layer 2 is formed by printing a pattern containing the animation character on the back surface of the sheet-like base material 1, and the first white printing layer 3 performs white printing on the back surface of the image printing layer 2. It was formed by this. As the printing method of the image printing layer 2 and the first white printing layer 3, known printing methods such as inkjet printing, gravure printing, offset printing, flexo printing, letterpress printing, and screen printing can be adopted. Further, as the printing ink, acrylic ink, urethane ink, vinyl ink, polyamide ink, nitrocellulose ink, UV ink, newspaper ink and the like are used.

Then, as shown in FIGS. 2, 4 to 6, most of the first white print layer 3 is formed of white ink, but a part of the first white print layer 3 is transparent (in the figure, dots for explanation). (Displayed in) Clear printing unit 3a. The clear printing portion 3a is arranged at a position overlapping the glossy portion 2a of the image printing layer 2, which is the target of glossing, specifically, the eyes of the animation character, a part of the hair, and the mark in the lower right corner. (See FIGS. 1 and 5). The position and shape of the glossy portion 2a can be arbitrarily changed.

Here, in the first white printing layer 3, even if the clear printing portion 3a is not printed (even as a space without ink), the glossy portion 2a of the image printing layer 2 is caused by the light reflection of the lens film 5 described later. It is also considered that the gloss can be given to the print. However, in reality, high glossiness cannot be obtained due to the action of air entering a space without white ink, so it is desirable to provide a transparent clear printing unit 3a as in the embodiment.

The adhesive tape 4 is for attaching the lens film 5 to the back surface of the first white printing layer 3, and employs an OCA (Optical Clear Adhesive) tape using a highly transparent acrylic adhesive. .. Instead of such an OCA tape, an adhesive such as an acrylic pressure-sensitive adhesive, a urethane-based adhesive, or an ethylene-vinyl acetate-based adhesive is used alone to bond the first white printing layer 3 and the lens film 5. May be done.

As shown in FIGS. 7 and 8 (a) and 8 (b), the lens film 5 is formed by depositing aluminum on one surface (front surface side) of a base film 5a made of a polyethylene terephthalate film to form a thin-film vapor deposition layer 5b. It is a thin-film deposition film. Grooves having a saw blade shape in cross section are arranged concentrically on one surface so that the inclined surface faces radially outward, and the inclination angle of the saw blade of the groove is sequentially arranged from the center of the concentric circle to the radial outside. The enlarged pattern 7 is formed in three rows vertically and horizontally. The inclined surface of each groove reflects light as a refracting surface, so that each pattern 7 looks like a convex spherical surface from the front surface side and looks like a concave spherical surface from the back surface side. That is, in this lens film 5, a plurality of patterns 7 arranged vertically and horizontally have the same function as a general Fresnel lens.

Therefore, when the front surface of the lens film 5 is attached to the back surface of the first white printing layer 3 with a transparent adhesive tape 4, the glossy portion 2a of the image printing layer 2 becomes visible when the image display body is viewed from the front surface side. The position where it looks shining changes depending on the viewing angle, and it rises convexly as a whole and looks three-dimensional.

Specifically, the position where the glossy portion 2a of the hair appears to shine changes depending on the viewing angle, so that a convex three-dimensional effect is created on the entire head of the anime character, and depending on the viewing angle, the pupil of the anime character. By changing the shining position of the glossy portion 2a, it is possible to obtain a visual effect such that a convex three-dimensional effect is created in the pupil of the animation character.

In this embodiment, an image display body that displays an image of an animated character has been described as an example. However, for example, the present invention is applied to an image display body that displays an image of a fish covered with scales, and fish scales and eyes. The portion displaying the above may be the glossy portion 2a, which makes it possible to obtain a visual effect such as creating a convex three-dimensional effect on the surface of the fish.

The second white printing layer 6 is formed by performing white printing on the back surface of the lens film 5 using the same printing method and printing ink as the first white printing layer 3, and the back surface (concave spherical surface) of the lens film 5 is formed. It only serves to hide the visible pattern). Therefore, instead of printing the second white printing layer 6, a white film or the like may be attached to the back surface of the lens film 5. Further, when the image display body is installed in a state where the back surface side is hidden, the second white printing layer 6, the white film, or the like may be omitted.

This image display body has the above-mentioned configuration, and during production, a step of printing the image printing layer 2 and the first white printing layer 3 on the back surface of the sheet-like base material 1 and a step of printing the image printing layer 3 on the back surface of the lens film 5 An image can be easily obtained by simply printing the second white printing layer 6 and bonding the first white printing layer 3 and the lens film 5 with the adhesive tape 4 without using a special material or device. It is possible to give luster to a part of. Further, since the surface thereof is covered with the sheet-like base material 1, even if the surface rubs against other objects during use, there is almost no effect on the glossiness, and the design can be stably maintained.

Further, since the lens film 5 is used as a film for imparting gloss to the image, the glossed portion looks three-dimensional due to the action thereof, and has excellent designability.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is indicated by the scope of claims, not the above-mentioned meaning, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

For example, in the embodiment, the surface of the lens film 5 (pattern 7 that looks like a convex spherical surface) is used to give gloss to a part of the image of the image display body and make that part look convex. Depending on the type of image, a pattern that looks like a concave spherical surface of a lens film may be used to make the glossed portion look concave. Further, instead of the lens film, a thin-film film such as a hologram film or a lenticular film can be used to impart designability utilizing the characteristics of the thin-film film.

As the base film of the vapor-deposited film, in addition to the polyethylene terephthalate film as in the embodiment, a resin film such as a polypropylene film or a polyvinyl chloride film can be used, and as a metal to be vapor-deposited on the base film. In addition to aluminum as in the embodiment, a single metal such as chromium or an alloy such as brass can also be used.

Further, as the film for imparting gloss to the image of the image display body, it is preferable to use a vapor-filmed film that can obtain stable metallic luster, but a metal-plated film or the like can also be used.

Further, in the embodiment, the image printing layer 2 is formed on almost the entire back surface of the sheet-like base material 1, but the image printing layer prints only the pattern and does not print the background portion, and the background of the image is the first white. It can be the white ink portion of the print layer. Alternatively, the image printing layer may be used for printing only a pattern, and the background portion of the first white printing layer may be used as a clear printing portion so that a glossy film serves as the background of the image.

Further, the sheet-like base material may be transparent, can show the image clearly, and can play a role of protecting the surface of the image. Therefore, depending on the application, in addition to the resin plate material as in the embodiment, a film made of glass or a resin such as polyester, polyethylene, polyethylene terephthalate, polypropylene, or polyvinyl chloride can be adopted.

The present invention can be widely applied not only to panels for advertising / promotion as in the embodiment, but also to various panels, posters, labels, and other image display bodies. Further, the image may be any one that displays characters, figures, patterns, photographs, etc. as a design in addition to the pattern as in the embodiment.
