Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a transparent decorative display body having a dot-like laminated image layer on a transparent substrate.

2. Description of the Related Art Conventionally, as a decorative body such as a decorative display panel, there is a display plate having transparency and displaying different patterns and characters on the front and back sides. As a method of manufacturing such a decorative display panel, a method of manufacturing by a printing method, a transfer method, an etching method, or the like has been proposed. For example, in the case of the transfer method, a transfer sheet obtained by sequentially laminating a coloring layer for forming each fine pattern on a transfer substrate is superimposed on a panel substrate on which an adhesive is formed in a fine pattern shape, and heated and pressed to transfer the transfer sheet. Is peeled off to form a fine laminated pattern on the substrate. However, it is necessary to set the adhesive strength of the colored layer on the transfer sheet side to the substrate to be smaller than the adhesive strength of the colored layer adhered through the fine pattern adhesive. Since the material of the colored layer is a resin component similar to the adhesive, it is extremely difficult to make a remarkable difference in the adhesive strength, and thus it has not been easy to smoothly perform the peeling operation after the transfer.

Also, in the printing method, the inverted part of the shape to be formed is printed with mask ink, and an ink layer is laminated on it,
Finally, there was a method that lifts off the mask ink and removes it together with the ink layer.However, this method can only be printed using the silk screen printing method due to the adhesive strength between the mask ink and the base material, resulting in high cost. There was a problem with poor workability.

(Object of the Invention) An object of the present invention is to easily and satisfactorily produce a transparent decorative display body having a dot-shaped laminated image layer on a transparent substrate.

(Constitution of the Invention) In the present invention, one or more desired image layers are laminated on one or both sides of an opaque or translucent resin or paper support sheet to form a laminated image sheet, A sheet and a transparent or opaque thin resin film made of vinyl chloride are adhered, and then the thin resin film side of the image sheet is superimposed on a transparent resin substrate mainly composed of the same or different material as the thin resin film. After temporary bonding by pressurizing or heating and pressing, a large number of cylinders are cut and cut from the sheet side to the thin resin film, and the half-cut cylinder region is left on the transparent resin base material side, leaving the thin resin film above. Forming a tubular laminated image layer on the substrate by peeling the laminated image sheet in a net-like manner, and then bonding and fixing the laminated image layer to the substrate by heating and pressing the laminated image layer. Having decorative display It is a manufacturing method.

(Effect of the Invention) The method of the present invention is to perform half blanking of a laminated image layer formed in advance on a transparent base material by using a blanking die in which a large number of cylindrical half blanking blade dies are arranged. The tubular portion of the image forming layer, which has been half-punched into a tubular shape, is left on the transparent substrate, and only the reticulated portion of the inverted pattern is peeled off from the transparent substrate. A thin film of a transparent resin film made of vinyl chloride is temporarily adhered between the transparent substrate and the image layer, and the thin film of the transparent resin film can be used as a release layer to smoothly perform a net-like peeling operation after half-blanking. It is. The dot-like image layer remaining on the substrate after peeling can be heated and pressed to cause the thin film resin film to be fused to the substrate and to be strongly adhered to the substrate.

(Example) The method of the present invention will be described in detail with reference to one example. FIG. 1 (a) shows a first colored layer 2 on the front and back of an opaque or translucent film-like support sheet 1 such as a resin film or paper. And the second colored layer 3, and a laminated image sheet 5
To form The second colored layer and the second colored layer in the present invention are those on which coloring, characters, patterns, etc. are applied as appropriate. For example, monochromatic, multicolored line drawings, gradation reproduction images, etc. Can be set. Subsequently, a thin transparent resin film 4 made of vinyl chloride (for example, having a thickness of about 10 to 40 μm) is bonded and laminated on either the first coloring layer 2 or the second coloring layer 3. The film 4 is formed on the colored layer 2 or the colored layer 3 by a coating method such as extruder coating or a laminating method. Next, (c) the transparent resin film 4 of the laminated image sheet 5 and the transparent substrate 6 made of vinyl chloride are superimposed, and heated and pressed at least at a temperature equal to or lower than the melting point of the resin to temporarily adhere. The thin transparent resin film 4 and the transparent substrate 6 are made of the same resin material, and the thin transparent resin film 4 is made of a flexible film (such as a resin in which a plasticizer is added to the main body resin) and has a self-adhesive property. It is used for temporary bonding. As the transparent substrate 6,
Low- or high-polymerized vinyl chloride can be used, but other resins such as acrylic resin, polystyrene, and polyester can also be used. Next, FIG. 1 (d) shows a half-cut cutting template 8 in which a large number of small-diameter (for example, 3 to 10 mm diameter) cylindrical half-cutting blade dies 7 are arranged on the plate in the vertical and horizontal directions. By pressing from above, the image sheet 5 is cut to the thin resin film 4. 9 is a half-cut cutting line. After the half-cutting cutting, the thin film resin film 4 in the cylindrical laminated image forming area is left on the transparent substrate 6, and delamination is performed from the temporary adhesion portion between the thin film resin film 4 and the transparent substrate 6. Is performed, and the image sheet 5 is peeled off in a net shape to form a dot-like laminated image a as a cylindrical laminated image on the transparent substrate 6 (e). Then, pressure is applied while heating to about 100 to 150 ° C. from above the image a, and the temporary adhesive portion between the thin film resin film 4 and the transparent substrate 6 is bonded and fixed to produce a decorative display body having a see-through property. Things.

In the decorative display body obtained by the method of the present invention shown in FIG. 1 (e), the portion where the dot-like laminated image a is not formed (the mesh portion) passes through the transparent substrate 6 Can be seen through from each other, the pattern of the first colored layer 2 can be observed from one side of the substrate 6, and the translucent or opaque support sheet 1 (having a concealing action) can be seen from the other side. The first colored layer 2 is incomplete or completely hidden, and the second colored layer 3
Only the picture by can be observed. In addition, the shape of the half-cutting die 7 in the method of the present invention is not limited to a cylindrical shape, and an appropriately shaped blade can be used in addition to a polygonal rectangular tube or the like.

FIG. 2 shows another embodiment of the method of the present invention, in which an opaque base coloring layer 10 and an opaque coloring layer 10 using an opaque coloring material are sequentially applied to one surface of a support sheet 1, and the other surface is applied to cover the other surface. In this case, a laminated image sheet 5 is formed by laminating a base coloring layer 11 and a second coloring layer 3 having different properties. After bonding the thin transparent resin film 4 to one surface of the sheet 5 and superimposing and temporarily bonding the transparent resin film 6 to the transparent resin base material 6, the predetermined half blanking process shown in FIG. It is for producing a decorative display. In the case of this embodiment, since the base coloring layers 10 and 11 are laminated on the support sheet 1, the support sheet 1 does not necessarily have to be opaque as in the one embodiment, but is a transparent film. You may.

FIG. 3 shows another embodiment of the present invention, in which a base layer 10 and a first coloring layer 2 having an opaque color using an opaque coloring agent such as ink are laminated on one side of the supporting sheet 1 and then the supporting sheet 1 is laminated. A colored opaque (or colored transparent) thin film resin film 12 is bonded to the other side of the film 1 and the thin film resin film 12 and the transparent substrate 6 are temporarily bonded to each other. Through a predetermined half blanking process and a heating and pressing bonding step, a decorative display body having a see-through property in which a dot-like laminated image a as shown in FIG. 4 is formed on the transparent base material 6 is manufactured.

(Effects of the Invention) In the method of the present invention, a laminated image sheet provided with a concealing layer in which a color, a character, a pattern, and the like are appropriately formed on a support sheet by a normal printing method or the like, and a transparent resin base material via a thin resin film. After the temporary bonding, after the half-cutting of the thin film resin film to the temporary bonding from the support sheet side in the form of dots, unnecessary areas are peeled off and removed from the temporary bonding portion in a net-like manner. Fine registration for image formation such as color misregistration prevention in printing etc. other than image layout operation is unnecessary, and dot-like laminated images formed on transparent base material are formed by cutting. Since a clear image of the edge of the image is obtained, and the peeling treatment is performed by a peeling operation from the temporarily bonded portion, a remarkable effect such that the peeling operation can be performed smoothly is exhibited.
