Description

Technical Field

[0001] The present invention relates to a three-dimensional sticker that is attached and decorated to small items, bags, mobile communication terminals, etc.

Background Art

[0002] Conventionally, in order to decorate small items, bags, mobile communication terminals, etc., stickers with an adhesive seal on the back have been used. Recently, thick stickers have gained popularity due to their tactile feel and three-dimensional appearance. Some thick stickers have a thickness by providing a space filled with a transparent resin formed three-dimensionally on the printed surface.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, if there is a space filled with a transparent resin formed three-dimensionally on the printed design, when viewed from an oblique direction on the side, for example, other than the front, the design appears distorted. When there is a sharp corner part when viewed directly from the side in the three-dimensionally formed space, the printed design appears particularly distorted at the sharp corner part. Also, by viewing the printed surface through the space filled with the transparent resin, the printed design becomes unclear.

Means for Solving the Problems

[0005] Therefore, as a means for solving the above problems, the three-dimensional sticker according to the present invention includes a flat substrate and a skin layer provided on the surface of the substrate. The skin layer forms a close-contact region that adheres to the entire circumference along the outer peripheral edge of the substrate, and forms an enclosed space between the substrate and the central portion rather than the close-contact region. A liquid resin is enclosed in the enclosed space, and has a printing layer provided on the front side of the skin layer, and the printing layer has a three-dimensional structure that smoothly bulges from the close-contact region toward the central portion of the enclosed space.

[0006] Further, a transparent protective layer may be provided on the surface of the printing layer. Alternatively, the outer edge of the printing layer may be provided so as to be slightly outside the boundary between the close-contact region and the enclosed space along the boundary.

[0007] Thereby, since the outer edge of the printing layer can be formed in the plane of the front surface, when observing the printed design, the outer edge can be visually recognized at almost the same angle with respect to the line of sight. Therefore, by making a difference in the appearance from the bulging three-dimensional structure, the three-dimensional structure strongly stands out, and the area of the design printed on the bulging three-dimensional structure can be emphasized.

[0008] The flat substrate, the skin layer, and the protective layer are made of a thermoplastic resin, for example, polyurethane or polyvinyl chloride (PVC). The liquid resin is, for example, an epoxy resin. Since the liquid resin is enclosed in the enclosed space, the three-dimensional sticker according to the present invention can have a moderate touch feeling. The printing layer is printed on the surface of the skin layer by, for example, inkjet printing or screen printing. It is preferable to print on the skin layer before the liquid resin is enclosed. This is because accurate printing can be performed with the flat surface of the skin layer as the printing target by printing before enclosing the liquid resin.

Effects of the Invention

[0009] According to the present invention, by having a printed layer provided on the front side of the epidermal layer and having a three-dimensional structure in which the printed layer smoothly bulges from the adhesion region toward the central portion of the enclosed space, the printed design can be clearly seen without distortion not only from the front but also from the side diagonal direction.

[0010] In addition, since the printed design exists on the three-dimensional structure that smoothly bulges from the adhesion region toward the central portion of the enclosed space, a continuous and integral design can be used from the non-bulging part to the bulging part.

[0011] Furthermore, by providing a transparent protective layer on the surface of the printed layer, not only can the printed layer be prevented from being damaged by friction or the like, but also it can have a shiny feature. Also, since the printed layer is provided along the boundary between the adhesion region and the enclosed space, the design printed on the bulging three-dimensional structure can give a strong impression of floating up.

Modes for Carrying Out the Invention

[0013] Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. In this specification and the drawings, for components having substantially the same functional configuration, the same reference numerals are given and redundant description is omitted.

[0014] The three-dimensional sticker 1 according to this embodiment includes a flat substrate 2 and a skin layer 3 provided on the surface of the substrate 2. The skin layer 3 forms a close-contact region 5 that adheres to the entire circumference along the outer peripheral edge 4 of the substrate 2, and forms an enclosed space 6 between the substrate 2 in the central portion rather than the close-contact region 5.

[0015] A liquid resin 7 is enclosed in the enclosed space 6 and has a printing layer 8 provided on the front side of the skin layer 3. The printing layer 8 is formed in a three-dimensional structure that smoothly bulges from the close-contact region 5 toward the center of the enclosed space 6. Thereby, the design printed on the printing layer 8 can be clearly seen without distortion not only from the front but also from the side diagonal direction. Further, since the resin enclosed in the enclosed space 6 is liquid, a three-dimensional structure that smoothly bulges can be realized from the entire circumference of the enclosed space 6 toward the center.

[0016] A transparent protective layer 9 is provided on the surface of the printing layer 8. The protective layer 9 prevents the printing layer 8 from being damaged by friction or the like. Further, due to the transparent protective layer 9, the printing layer 8 can have a glossy feature.

[0017] The outer edge 4 of the printing layer 8 is provided along the boundary 12 between the close-contact region 5 and the enclosed space 6 so as to be slightly outside the boundary 12. Thereby, since the outer edge 4 of the printing layer 8 can be formed in the plane of the front surface, when observing the printed design, the outer edge 4 can be visually recognized at substantially the same angle with respect to the line of sight. Therefore, by giving a difference in angle in the way of appearance with the bulging three-dimensional structure, the three-dimensional structure strongly stands out, and the area of the design printed on the bulging three-dimensional structure can be emphasized.

[0018] The skin layer 3 is in close contact with the substrate 2 by the close-contact region 5. The substrate 2 includes an adhesive layer 10 on the back surface. When the three-dimensional sticker 1 is sold, the back surface of the three-dimensional sticker 1 includes a backing sheet 11. However, when the three-dimensional sticker 1 is used by sticking it to a small item or the like, the backing sheet 11 can be peeled off and stuck to the small item or the like by the adhesive layer 10.

[0019] Note that although the three-dimensional sticker 1 shown in Fig. 2 is in the shape of a cross, the three-dimensional sticker according to the present invention is not limited to the shape of a cross, and may be, for example, round, square or rectangular, or may be in a shape conforming to the shape of characters, animals, or characters printed on the printing layer.
