Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game / education jigsaw puzzle or display, a picture to be fitted, and the like.

[0002]

2. Description of the Related Art As a most popular form of conventional jigsaw puzzles, there is one in which a colored image is printed on a cardboard and then subjected to press die cutting with a Thomson die to make it into small pieces. However, many jigsaw puzzles in Japan are set up in a suitable frame and displayed as interior decoration after the puzzle is restored and completed rather than the percentage of purchase for the purpose of game and competition in Europe and America. Reflecting such a market, jigsaw puzzles themselves are also diversifying.For example, a puzzle is mixed in which fluorescent paint is mixed with an image to print an image, and the completed puzzle is illuminated after turning off at night. After completion, it is disclosed that the building, castle, etc. are completed as a three-dimensional miniature, and the decorativeness after completion is further enhanced.

In view of the market trends as described above, there has been no jigsaw puzzle which can be decorated as a transmissive display having an excellent appearance by combining an appropriate backlight after the image restoration is completed.

As a conventional technique, the concept of a transparent jigsaw puzzle is disclosed in Japanese Utility Model Laid-Open No. 05-15993, Japanese Patent Publication No. 04-71557, etc. The image is completed as a multicolor image (reflection image), and the image is not displayed as a transmission image in a light emitting state by light from the back surface. The latter discloses an example in which an EL surface light source is used as a backlight, but the jigsaw puzzle only discloses that it partially has a light-transmitting property.

Therefore, there is no known jigsaw puzzle in which an image can be easily identified when enjoying a puzzle and a sufficient color density is maintained when the transmitted light is illuminated by a backlight. It is necessary for such a jigsaw puzzle to be handled as a reflection image when the puzzle is formed, and to have a good function as a light transmission image in the state of being decorated after completion. In addition, it is necessary for the interior of the room to have some light resistance and fading resistance to transmitted light. However, there was no jigsaw puzzle that had the above properties.

[0006]

SUMMARY OF THE INVENTION In view of the above points, the object of the present invention is to allow the image to be easily viewed as a reflection image when the puzzle is restored, and to use the completed image as a light transmission panel, and at this time, to obtain sufficient color density. Is to provide a jigsaw puzzle having images of.

[0007]

SUMMARY OF THE INVENTION The present invention is a jigsaw puzzle having an image formed by a colored layer having an optical density of at least one color of 0.5 to 3 on a transparent substrate.

[0008]

EXAMPLES The present invention will be described in detail below with reference to examples. Generally, a jigsaw puzzle image is formed by using a multicolor forming printing technique such as offset printing or gravure printing. In this printing method, it is difficult to increase the coloring density because the ink thickness is thin, and as described above, it is good as a reflection image when forming a puzzle, but the color density cannot be sufficiently maintained when transmitting light. Therefore, it is formed by the method described in Japanese Patent Application Laid-Open No. 3-228087, Japanese Patent Application No. 5-316644, which can form a multicolor image capable of both reflection and transmission as an image forming material.

The method for forming an image forming material disclosed in Japanese Patent Laid-Open No. 3-228087 includes the following steps (a) to (f). (A) A photosensitive coloring composition containing a dye or a pigment thereon, with or without a release layer provided on the support, or a coloring material layer containing the dye or the pigment and a photosensitive resist layer. A step of image-exposing a photosensitive image-forming material formed by stacking and an image through a color separation mask, (b) a step of developing the image-exposed photosensitive image-forming material to form a color image on a support, c) transferring the color image onto the photopolymerizable image-receiving layer of the image-receiving material, (d) (a)-
A step of transferring at least another color image having a different hue formed in the same manner as in (b) in alignment with the photopolymerizable image-receiving layer, and (e) a multicolor image formed on the image-receiving layer. Transferring the image onto a light-transmissive second support having a photopolymerizable adhesive layer, (f) exposing the photopolymerizable image-receptive layer of the image-receptive material and the light-transmissive second support. A step of adhering the photopolymerizable adhesive layer by photopolymerization.

The method for forming an image forming material described in the above-mentioned Japanese Patent Application No. 5-316644 discloses a semitransparent white layer,
A first color image layer (preferably formed by gravure printing) formed on one surface of the white background layer, and the same color image layer as the first color image layer, and the other surface of the white background layer To the first
To form a second color image layer. The optical density of this white background layer (broadly speaking, “white layer”) is preferably 0.01 to 0.5. This is because if it is less than 0.01, the white layer has no effect. This is because if it exceeds 0.5, the amount of transmitted light as a transmitted image is significantly reduced.

At least one color of the color layer density in the image formation is 0.5 with a transmission densitometer DM-500 manufactured by Dainippon Screen Co., Ltd. from the viewpoint of the visibility at the time of puzzle restoration and the beauty at the time of transmitting light. It has been found that it is preferably set to ˜3, preferably 0.8 to 2. That is, when the optical density is low, the color is thinned at the time of transmission as described above, and when it is too high, the entire image becomes dark when the reflected image is visually recognized, which makes it difficult to identify the image.

Table 1 shows an example of the optical densities of the three primary colors and black used in forming a multicolor image.

[0013]

[Table 1]

Although the above-mentioned color density range is an appropriate range as the puzzle for this application, it is desirable to attach a white layer to the colored layer for practical use. Common jigsaw puzzles use white ink or white cardboard white, but these all have very poor light transmission, and the use of these in the transmission jigsaw that the present invention intends to provide provides high brightness. Since it is necessary to apply a backlight frame, these become expensive and large in size, and the value as a handy interior interior is greatly reduced.

A puzzle may be formed based on the surface color white on the frame backlight side, but in this case, it is a small piece (1 piece).
It is not a solution for poor visibility when picking up one by one. As a result of trial and error to solve this point, the optical density of the white layer is 0.01 to 0.5, preferably 0.01 to 0.5.
It is suitable to form a white layer of 0.2, and as the optimum white layer, a transparent resin layer having a matte surface is formed on the coloring layer, and a white background is formed by utilizing light diffusion on the surface (optical density). It was found that it is possible to provide white without reducing transmitted light. of course,
A film material containing a white pigment, an ink material, or the like may be coated on the colored layer, or may be provided between two image layers as in the above-mentioned Japanese Patent Application No. 5-316644. However, in this case, it is difficult to achieve both whiteness and translucency that are higher than those of the matte layer. The method of using the white pigment and the method of forming the matte layer may be combined.

Next, the image is transferred to a transparent resin substrate (thickness 0.5).
To 2.0 mm) in consideration of image adhesiveness, mold release property, dimensional stability, transparency, light resistance, etc., for example, surface-treated polypropylene, polycarbonate, ionomer resin, acrylic / acrylic rubber copolymer, ABS resin, etc. Ethylene / ethyl acrylate copolymer, ethylene /
A highly transparent hot-melt adhesive layer of acrylic acid copolymer, ionomer resin, ethylene / vinyl acetate copolymer or the like was formed with a thickness of several tens of microns by appropriate coating, laminating or the like to transfer and form the image layer. Alternatively, an acrylic pressure-sensitive adhesive may be provided for bonding to the image layer as in the hot melt resin.

In the case of the method described in JP-A-3-228087, the white background is formed by matting the transparent resin layer on the surface,
The surface of the second support of the image receiving layer can be easily formed by matting and peeling the image, transferring the image to the substrate, exposing it, and peeling the support. Japanese Patent Application 5
In the case of the method described in Japanese Patent No. 316644, after image transfer, a transparent photosensitive resin formed on a support having a matte surface is laminated and then exposed to ultraviolet rays to cure to transfer the matte surface, or a matting agent is added. The transparent ink may be formed by screen printing or the like. At that time, the degree of surface mat can be 20 or less, and 10 or less is preferable in terms of glossiness (60 °).

In this case, the jigsaw puzzle of the present invention is one in which the colored image layer is laminated and adhered from both sides by the transparent resin substrate and the surface mat layer made of the transparent resin. More specifically, the transparent resin substrate is used as the display side, and the colored layer and the mat layer are formed in this order on the back side.

Further, it is effective to form the mixture to a suitable thickness so that the mixture can be sufficiently protected with a mixture of a pigment and a resin component in order to suppress the color fading, and the layer thickness of the colored layer is set to 0. It was good to set it to 5 to 5.0 microns.

Further, an ultraviolet absorber may be appropriately added to the resin substrate, the image adhesive layer (which may be present between the image and the resin substrate and / or the surface matte layer), the surface matted transparent resin layer and the like. It is effective.

The display side of the image may be on the front side or the back side of the substrate. However, when the front side is on the substrate side, part of the light entering the transparent substrate is totally reflected and transmitted inside the substrate. Since it remains without it, the image looks brighter and clearer, and the image visibility is excellent when the puzzle is restored. Further, even when the light is emitted by the backlight, the image can be provided in a clear manner by the effect of guiding the transmitted light in the transparent substrate. Of course, the backlight used may be a general-purpose electric type (built-in fluorescent lamp type) backlight,
On the back side of the jigsaw puzzle, it is preferable to form a triangular prism which is a path changing means for refracting incident light so that the light is irradiated to the front side. A side view of the jigsaw puzzle with a triangular prism is shown in FIG. 3, and a front view thereof is shown in FIG. In these figures, 11 is a jigsaw puzzle, 12 is a triangular prism, and 13 is a matte surface. For example, the angle θ of the triangular prism is 70 °, and the triangular projection pitch P is 0.26 mm.
Is. As shown in FIG. 5, by suspending it vertically from the ceiling and hanging the indoor light 31 for indoor certification fixed to the ceiling 30 so that it is located in the upper rear part, the indoor light 31 can be used as a backlight. , It can be offered to general consumers at a price system that can be purchased. However, the light refracting means is not limited to the triangular prism, and a sheet having a similar shape and a light diffusing sheet on which matte printing or the like is formed can be appropriately applied.
