BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a sheet set 10 according to the present embodiment includes a plurality of decorative sheets 20 formed as playing cards. The plurality of decorative sheets 20 are picture cards (“A”, “J”, “Q”, “K” of each mark), number cards (“2” to “10” of each mark), and joker cards. including.

The decorative sheet 20 is decorated with a first design Z1 visible from the front side (first surface side) and a second design Z2 visible from the back side (second surface side). The first pattern Z1 is a pattern including a combination of any of "A" to "K" and any of diamonds, hearts, spades, and clubs, or a joker pattern. Therefore, the first pattern Z1 is a non-common pattern that differs for each decorative sheet 20. FIG. The second pattern Z2 is a common pattern that is common among the decorative sheets 20 .

The structure of the decorative sheet 20 will be described below with reference to FIGS.

As shown in FIGS. 2 to 4, the decorative sheet 20 is formed on a transparent sheet 21 serving as a base material and a surface 21A (first surface) of the transparent sheet 21, each serving as an element of the first pattern Z1. A plurality of first pattern elements 22 and a plurality of second pattern elements 23 formed on the back surface 21B (second surface) of the transparent sheet 21 and serving as elements of the second pattern Z2 are provided.

The plurality of first pattern elements 22 are formed in a plurality of dots. More specifically, the plurality of first pattern elements 22 are each rectangular and arranged in a matrix at intervals to represent the first pattern Z1 as a whole. Similarly, the plurality of second pattern elements 23 are also formed in a plurality of dots. More specifically, the plurality of second pattern elements 23 are each rectangular and arranged in a matrix at intervals to represent the second pattern Z2 as a whole. As shown in FIGS. 4 and 5 , the plurality of first pattern elements 22 and the plurality of second pattern elements 23 overlap each other when viewed from the thickness direction of the transparent sheet 21 . The shape of each of the pattern elements 22 and 23 is arbitrary, and may be a dot shape such as a rhombus or a circle.

As shown in FIG. 4, the first region R1 between the plurality of first pattern elements 22 and the second region R2 between the plurality of second pattern elements 23 are spaces. Also, the first region R1 and the second region R2 overlap each other when viewed from the thickness direction of the transparent sheet 21 . A portion X extending from the first region R1 to the second region R2 via the transparent sheet 21 is transparent as a whole. Therefore, the portion X is also a see-through portion through which a user looking at the front side or the back side of the decorative sheet 20 can see through the transparent sheet 21 to the opposite side or the front side. Hereinafter, this portion X will also be referred to as a see-through portion X. The first region R1 and the second region R2 constitute a see-through portion X. As shown in FIG. As shown in FIGS. 2 and 3, the see-through portion X is arranged between the first pattern Z1 and the second pattern Z2 when viewed from the thickness direction of the transparent sheet 21. As shown in FIG. When viewed from the thickness direction of the transparent sheet 21, the see-through portion X is formed in a grid pattern in which a plurality of vertical lines and a plurality of horizontal lines intersect.

As shown in FIG. 4, each of the plurality of first pattern elements 22 is formed between a first colored layer 22A that constitutes the first pattern Z1 and between the first colored layer 22A and the transparent sheet 21. and a first base layer 22B serving as a base for the colored layer 22A. Each of the plurality of second pattern elements 23 includes a second colored layer 23A forming the second pattern Z2, and a second base layer 23B and a light shielding layer 23C formed between the second colored layer 23A and the transparent sheet 21. And prepare. In the following, the second pattern element 23 will be explained first, and then the first pattern element 22 will be explained.

The light shielding layer 23C of the second pattern element 23 is formed of a metal foil having metallic luster, such as aluminum foil, and is formed from the layers 22A and 22B of the first pattern element 22 and the layers 23A and 23B of the second pattern element 23. , shields light so as not to be transparent to the other. The light shielding layer 23C is printed by cold foil printing, for example. 23 C of light shielding layers may be formed of materials other than a metal.

The second base layer 23B is, for example, a white layer, and hides the color of the light shielding layer 23C to reduce the influence of the color on the second colored layer 23A. The second base layer 23B includes a 2-1 base layer 23BA printed on the light shielding layer 23C and a 2-2 base layer 23BB printed on the 2-1 base layer 23BA. This two-layer structure enhances the concealment function.

The second colored layer 23A is color-printed on the 2-2 base layer 23BB. The individual second colored layers 23A arranged in a matrix form each part of the second pattern Z2. Thereby, the second pattern Z2 is represented by the entirety of the plurality of second colored layers 23A.

The layers 23BA and 23BB of the second base layer 23B and the light shielding layer 23C are formed in the same shape when viewed from the thickness direction of the transparent sheet 21 and match. The second colored layer 23A is formed slightly larger than the second base layer 23B and the light shielding layer 23C when viewed from the thickness direction of the transparent sheet 21 so that the second base layer 23B is less visible to the user. In FIG. 4, the edge of the second colored layer 23A is schematically drawn, so it is drawn floating with respect to the transparent sheet 21, but the actual edge is the second base layer 23B and the light shielding layer 23C. cover the sides of the

The first base layer 22B of the first pattern element 22 is, for example, a white layer, and hides the color of the light shielding layer 23C, which overlaps with the transparent sheet 21 in the thickness direction of the transparent sheet 21, so that the color of the first colored layer 22A is hidden. Reduce color effects. The first base layer 22B consists of a 1-1 base layer 22BA printed on the surface 21A of the transparent sheet 21 and a white 1-2 base layer 22BB printed on the 1-1 base layer 22BA. and including. This two-layer structure enhances the concealment function.

The first colored layer 22A is color-printed on the 1-2 base layer 22BB. The individual first colored layers 22A arranged in a matrix form each part of the first pattern Z1. Thereby, the first pattern Z1 is represented by the entirety of the plurality of first colored layers 22A.

The layers 22BA and 22BB of the first base layer 22B are formed in the same shape when viewed from the thickness direction of the transparent sheet 21 and match. The first colored layer 22A is formed slightly larger than the first base layer 22B when viewed from the thickness direction of the transparent sheet 21 so that the first base layer 22B is less visible to the user. In FIG. 4, the edge of the first colored layer 22A is also schematically drawn, and the actual edge covers the side of the first base layer 22B.

As shown in FIG. 5, the first colored layer 22A is formed to be smaller than the light shielding layer 23C of the second pattern element 23 overlapping the first colored layer 22A when viewed from the thickness direction of the transparent sheet 21. The whole is covered with a light shielding layer 23C. In other words, when viewed from the back side of the decorative sheet 20, the light blocking layer 23C of the second pattern element 23 covers the entire first colored layer 22A. Therefore, when the decorative sheet 20 is viewed from the back side, the first colored layer 22A is prevented from protruding from the light shielding layer 23C.

As described above, in the decorative sheet 20, when viewed from the thickness direction of the transparent sheet 21, the first pattern Z1 and the second pattern Z2 include lattice-shaped patterns that are seen through the transparent sheet 21 by the user. A see-through portion X is provided. As a result, the patterns Z1 and Z2 are expressed together with the see-through portion X, so that the design of the decorative sheet 20 is improved. In such a decorative sheet 20, the first pattern element 22 and the second pattern element 23 representing the first pattern Z1 and the second pattern Z2, respectively, are formed on the front surface 21A and the back surface 21B of the transparent sheet 21, respectively. there is Therefore, since the first pattern Z1 and the second pattern Z2 are not visually recognized through the transparent sheet 21, the visibility of the first pattern Z1 and the second pattern Z2 is improved.

Furthermore, since the light shielding layer 23C is provided between the first colored layer 22A and the second colored layer 23A, one of the colored layers 22A and 23A can be hardly seen through the other. As a result, the first pattern Z1 and the second pattern Z2 are less likely to interfere with each other, so that both can be formed as separate patterns.

Furthermore, the first base layer 22B can hide the light shielding layer 23C, which overlaps with the transparent sheet 21, on the front side, thereby reducing the color influence of the metallic luster of the light shielding layer 23C on the first colored layer 22A. be. Similarly, the second base layer 23B reduces the color effect of the metallic luster of the light shielding layer 23C on the second colored layer 23A. Instead of reducing the influence of color, a metallic luster may be imparted to the first colored layer 22A by, for example, thinning the first base layer 22B. Similarly, the second colored layer 23A may be provided with a metallic luster by, for example, thinning the second base layer 23B. The underlayers 22B and 23B may have a color other than white, and may not have a two-layer structure.

Furthermore, when viewed from the back side of the decorative sheet 20, the light shielding layer 23C of the second pattern element 23 is formed larger than the first pattern element 22 overlapping the second pattern element 23, especially the first colored layer 22A, It covers the entire first colored layer 22A. As a result, even if the first colored layer 22A is slightly misaligned when the decorative sheet 20 is formed, the first colored layer 22A does not easily protrude from the light shielding layer 23C when viewed from the thickness direction of the transparent sheet 21. Due to the protrusion, the first colored layer 22A is visible from the back side, and as a result, the inconvenience that the first pattern Z1 formed by the first colored layer 22A is seen through to the back side is suppressed. In this embodiment, the decorative sheet 20 is a playing card, and the first pattern Z1 is a non-common pattern representing numbers, marks, and the like. Therefore, if the first pattern Z1 were to be transparent on the back side, the contents of the non-common pattern would become known to the user, and the fairness of the game would be lost. On the other hand, the fairness of the game is not affected even if the second symbol Z2, which is a common symbol, is transparent to the front side. By covering the entire first colored layer 22A with the light shielding layer 23C as described above, even if there is a risk that the second pattern Z2 may be seen through to the front side, the first pattern Z1 is at least suppressed from being seen through to the back side. Keep the game fair.

Furthermore, as described above, the light shielding layer 23C is larger than the first colored layer 22A and covers the entire first colored layer 22A when viewed from the thickness direction of the transparent sheet 21, so that when viewed from the thickness direction, the metal light shielding layer The layer 23C protrudes from the first colored layer 22A, that is, the first pattern element 22, and the protruding portion is viewed by the user from the front side together with the first colored layer 22A. In this case, the second pattern Z2 represented by the entirety of the plurality of first colored layers 22A is given the metallic luster of the protruding portion of the light shielding layer 23C, and the second pattern Z2 is expressed with a unique touch. As a result, the decorative sheet 20 can have a high degree of design.

When the light shielding layer 23C covers the entire first colored layer 22A when viewed in the thickness direction of the transparent sheet 21, the contour of the light shielding layer 23C is within the contour of the first colored layer 22A when viewed in the thickness direction of the transparent sheet 21. The former contour and the latter contour may partially overlap each other (see FIG. 5). Further, only some of the plurality of light shielding layers 23C may be formed so as to be larger than the first colored layer 22A when viewed from the thickness direction of the transparent sheet 21 and cover the entirety.

Next, a method for forming the decorative sheet 20 will be described with reference to FIG. In the method of forming the decorative sheet 20, first, the transparent sheet 21 is prepared (step S11). The transparent sheet 21 is made of, for example, a transparent resin such as vinyl chloride, polypropylene, or polyethylene terephthalate.

Thereafter, a light shielding layer 23C is formed on the back surface 21B of the transparent sheet 21 by cold foil printing (step S12). For example, the adhesive is applied only to the area of the back surface 21B of the transparent sheet 21 where the light shielding layer 23C is to be formed. The adhesive may be applied by printing with a printer or the like (for example, offset printing). Thereafter, a metal foil (for example, aluminum foil), which is the material of the light shielding layer 23C, is applied to the entire back surface 21B of the transparent sheet 21 and peeled off, thereby removing the portion of the metal foil that is attached to the transparent sheet 21 with the adhesive. remains as the light shielding layer 23C. Thereby, a plurality of light shielding layers 23C are printed at the same time. The foil printed by cold foil printing may be made of a material other than metal foil.

After that, the 2-1 base layer 23BA, the 2-2 base layer 23BB, and the second colored layer 23A are sequentially printed on the light shielding layer 23C (step S13). Thereafter, the 1-1 base layer 22BA, the 1-2 base layer 22BB, and the first colored layer 22A are sequentially printed on the back surface 21B of the transparent sheet 21 (step S14). Each base layer is printed with white ink, and each colored layer is printed with color ink. For printing, offset printing or the like is adopted. The inks and adhesives used for printing may be UV (ultraviolet) curable. In this case, irradiation of ultraviolet rays is performed at an appropriate timing.

By forming the light-shielding layer 23C of each of the second pattern elements 23 by cold foil printing, the step of heating the transparent sheet 21 at a high temperature, which is different from crimping, becomes unnecessary. This widens the range of choices for the material of the transparent sheet 21 .

Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments. The present invention includes various modifications to the above-described embodiments that can be understood by those skilled in the art within the scope of the technical idea of the present invention.

The transparent sheet 21 may be transparent, and transparent includes colorless transparent, colored transparent, and translucent. The see-through through the see-through portion X includes not only the see-through that makes the opposite side of the decorative sheet 20 clearly visible, but also the see-through that makes the other side vaguely visible. The decorative sheet 20 may include at least one of a colorless transparent or colored transparent protective layer covering the first pattern element 22 and a colorless transparent or colored transparent protective layer covering the second pattern element 23 . In this case, regions R1 and R2 in FIG. 4 include portions of the protective layer that extend into those regions. The content of the design is arbitrary. The plurality of first pattern elements 22 and the plurality of second pattern elements 23 may be formed in concentric circles instead of dots.

The present invention may be applied to various cards other than playing cards, such as game cards and trading cards (including collection cards). In particular, the decorative sheet according to the present invention has the first pattern and the second pattern formed on the transparent sheet, and can give a special feeling to the whole than a normal non-transparent card. Suitable for cards. Both the first pattern and the second pattern may be non-common patterns. In this case, of the two non-common patterns on the front and back sides, the non-common pattern that is not desired to be seen through may be used as the second pattern. The present invention may also be applied to sheets other than cards, such as calendars. The first pattern as the non-common pattern may be different between some of the plurality of decorative sheets constituting one sheet set, and may be different between some of the plurality of decorative sheets. may be the same.
