Description

  The present invention relates to a three-dimensional decorative sheet that can express a three-dimensional pattern using a lens, a three-dimensional decorative object, a method for manufacturing a three-dimensional decorative sheet, and a method for manufacturing a three-dimensional decorative object.

  2. Description of the Related Art Conventionally, a decorative sheet that uses the principle of moire fringes due to light interference has been used for decoration, as the pattern and color change depending on the viewing angle (see, for example, Patent Document 1).

  This decorative sheet creates a three-dimensional pattern on the sheet by forming a continuous pattern of lenses on the surface of the transparent sheet and printing on the back surface to form the pattern portions on the front and back surfaces of the transparent sheet. It is a thing.

  In addition, a three-dimensional decorative printed metal plate has been devised in which a three-dimensional pattern with a three-dimensional effect is created on the metal plate. This three-dimensional decorative printed metal plate is manufactured by printing on a metal plate and thermocompression bonding a transparent resin film having a lens formed on the printed metal plate via an adhesive at a required thermocompression bonding temperature. (For example, refer to Patent Document 2). According to this method of manufacturing a three-dimensional decorative printed metal plate, it is possible to firmly press the transparent resin film on the metal plate by thermocompression bonding, and metal cans etc. by molding using the three-dimensional decorative printed metal plate as a material Products can be manufactured.

  Furthermore, a three-dimensional decorative printed metal plate in which a transparent resin film is more firmly bonded onto the metal plate has been devised (see, for example, Patent Document 3). This three-dimensional decorative printing metal plate is manufactured by forming a lens on a transparent resin film after thermocompression bonding a flat transparent resin film on a printed metal plate at a required thermocompression bonding temperature. The three-dimensional decorative printed metal plate manufactured by this manufacturing method can be used as a material for products such as various can containers because the transparent resin film is firmly bonded to the printed metal plate.

In addition, as a decorative sheet, a sheet in which a hologram is coated on the surface of paper is also commercialized.

  However, in a decorative sheet in which a pattern portion is formed on the front and back surfaces of a conventional transparent sheet, printing is performed on the back surface of the lens-attached transparent sheet. For this reason, at the time of printing, it is necessary to print while pulling the transparent sheet under tension. For this reason, pressure is applied to the transparent sheet, and there is a problem that the printing accuracy is lowered because the transparent sheet after printing shrinks. In addition, there is a technique for printing on a transparent sheet using a silk screen, but sufficient printing accuracy cannot be obtained. And the fall of printing accuracy is the cause of the quality fall of a three-dimensional decoration effect.

  In addition, in the conventional three-dimensional decorative printing metal plate, printing is performed on the metal plate side, so that the printing accuracy can be maintained, but since the transparent resin film is firmly thermocompression bonded to the metal plate by a hot pressing process, it is transparent later. It is not suitable for products that require removal of the resin film.

  Furthermore, it is desirable to apply a three-dimensional decoration not only to a metal plate but also to a decorative object composed of a wide variety of materials, and to apply a three-dimensional decoration even if the decorative object has a more complicated shape. May be desired. In addition, it may be desired to later remove the three-dimensional decoration once applied to the decoration.

  Embodiments of a three-dimensional decorative sheet, a three-dimensional decorative object, a three-dimensional decorative sheet manufacturing method, and a three-dimensional decorative object manufacturing method according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a sectional structural view showing an embodiment of a three-dimensional decorative sheet according to the present invention.

  The three-dimensional decorative sheet 1 is obtained by adhering a transparent resin film 4 to a printing sheet 2 via an adhesive 3. Printing is performed at a first pattern pitch on the transparent resin film 4 side of the printing sheet 2 to form a printing layer 5. The pattern pitch can also be referred to as the number of screen lines. The number of screen lines refers to the number of black lines (halftone dots) between 1 cm or 1 inch. Further, on the surface side of the transparent resin film 4, a large number of lenses 4A are formed two-dimensionally with a second pattern pitch. The lens 4A may be a convex lens or a concave lens. Furthermore, you may form not only the lens 4A but the continuous pattern which repeats the same unevenness like a tortoise-like protrusion on the surface side of the transparent resin film 4 by a 2nd pattern pitch in two dimensions.

  The first pattern pitch and the second pattern pitch are set to different values. A three-dimensional decoration effect having a sense of depth can be created according to the difference between the values of the first pattern pitch and the second pattern pitch.

  FIG. 2 is a cross-sectional view for explaining the decoration principle of the three-dimensional decorative sheet 1 shown in FIG.

  The patterns 5 a, 5 b, 5 c of the printing layer 5 formed on the surface of the printing sheet 2 have different visual states depending on the positional relationship with the lens 4 </ b> A formed on the transparent resin film 4. As shown in FIG. 2A, in the portion where the pattern 5a and the lens 4A completely overlap, the pattern 5a can be recognized even when viewed from all directions, for example, the X direction and the Y direction. On the other hand, as shown in FIG. 2B, when the overlap between the lens 4A and the pattern 5b is shifted by almost the radius of the lens 4A, the pattern 5b can be seen when viewed from the X direction, but when viewed from the Y direction. The pattern 5b cannot be recognized, and the pattern 5b may or may not be visible depending on the viewing direction. Further, as shown in FIG. 2C, if the pattern 5c is displaced by the radius of the lens 4A or more, the pattern 5c is not visible from the Y direction, and the pattern 5c is difficult to see from the X direction. 5c cannot be recognized.

  Therefore, each pattern 5a, 5b, 5c created by the printing layer 5 formed on the surface of the printing sheet 2 changes depending on the relative positional relationship with the lens 4A, that is, depending on the viewing angle.

  The transparent resin film 4 is made of transparent synthetic resin such as polyethylene, polypropylene, polyester, nylon, urethane, polyvinyl chloride, polyvinyl nitrate, polyacryl, and polyethylene terephthalate resin (PET) that transmits light. However, it is preferably composed of a polyester sheet from an environmental aspect, an acrylic sheet from a weather resistance aspect, and a soft vinyl chloride sheet from a flexibility aspect. The transparent resin film 4 may be translucently colored.

  The printing sheet 2 is preferably made of any material that has a sufficiently small expansion / contraction. More specifically, the material having a sufficiently small expansion / contraction is a material that can be expanded / contracted to such a degree that the quality of the three-dimensional decoration effect can be maintained even if the expansion / contraction is performed. As a material with sufficiently small expansion and contraction, according to the nature, a flexible material that can be bent, a non-flexible material with sufficiently small expansion and contraction, and a plurality of flexible materials and non-flexible materials are laminated. There are materials. A material suitable for the application is selected from these materials for the printing sheet 2.

  Specific examples of flexible materials include paper with small expansion and contraction, polyethylene, polypropylene, polyester, nylon, urethane, polyvinyl chloride, polyvinyl nitrate, polyacryl, PET and other resins, aluminum foil, and sealing sheets. .

  Paper that can be used as the printing sheet 2 includes printing paper and paper other than printing paper. Normal printing paper is coated paper, and there is non-coated paper as paper other than printing paper. Non-coated paper is classified into high-quality paper (high-grade paper), medium-quality paper (intermediate paper), and modified paper (lower-grade paper) according to the chemical pulp content. In general, non-coated paper having a chemical pulp content of 100% is called high-quality paper, and non-coated paper having a chemical pulp content of about 40% to 70% is called medium-quality paper. Paper usually expands and contracts about 3mm / m, and there is no paper that does not stretch. Non-coated paper has a larger amount of expansion / contraction than coated paper. Therefore, the non-coated paper can be used as the printing sheet 2 when good quality is not required for the three-dimensional decoration effect.

  On the other hand, the coated paper is a microscopic amount of expansion and contraction that can maintain the quality of the three-dimensional decoration effect, and therefore can be used as the printing sheet 2 when good quality is required for the three-dimensional decoration effect. it can. The coated paper is a paper in which a chemical such as a white pigment is applied to the surface of high-quality paper or medium-quality paper using a paste material such as starch. Coated paper is art paper, coated paper, medium coated paper, lightweight coated paper, medium lightweight coated paper, fine coating depending on conditions such as chemical application amount (coating amount), chemical pulp content, etc. Classified as paper. The coated paper is classified into a gloss type, a mat type, and a dull type according to the difference in coating, surface smoothness, and amount of drug applied.

  Details of the classification of printing paper are described in, for example, “DTP & Printing Mechanism Encyclopedia” issued by Works Corporation.

  As a technique for sufficiently reducing the expansion and contraction of the paper, there is seasoning in which the paper is exposed to a printing atmosphere such as room temperature and humidity at the time of printing to expand and contract in advance according to the printing atmosphere. Therefore, it is possible to use as the printing sheet 2 paper that has been subjected to seasoning and whose humidity and temperature are adjusted to sufficiently reduce expansion and contraction. Another technique for sufficiently reducing the expansion and contraction of paper is coating. For example, surface-treated coated paper, such as coated paper, synthetic paper, waterproof paper, and paper coated with a resin, can be used as the material for the printing sheet 2 because the expansion and contraction is sufficiently small. In addition, as an example of the laminate material, a sheet obtained by bonding paper on an aluminum foil can be given.

  In addition, a sealing sheet can be used as the printing sheet 2.

  FIG. 3 is a cross-sectional structure diagram of the three-dimensional decorative sheet 1 when a sealing sheet is used as the printing sheet 2 shown in FIG.

  As shown in FIG. 3, a sealing sheet 2 </ b> A can be used as the printing sheet 2. The sealing sheet 2A is configured by adhering the adhesive sheet 2B to the release paper 2C. The pressure-sensitive adhesive sheet 2B is obtained by applying a pressure-sensitive adhesive 2D to a sheet of paper, resin, metal foil or the like. As the adhesive sheet 2B, for example, a sheet obtained by applying an adhesive to the above-described coated paper can be used. The sealing sheet 2A that can be printed on the surface is commercially available and can be easily obtained. Even when the sealing sheet 2 </ b> A is used as the printing sheet 2, it is desirable that the sealing sheet 2 </ b> A is made of a material having sufficiently small expansion and contraction as described above.

  Thus, printing can be performed with high accuracy on a material having sufficiently small expansion and contraction. For example, even if the print layer is a still image such as a photograph or a landscape image or an illustration that requires accuracy, it can be printed on the printing sheet 2 with sufficient accuracy. On the other hand, for example, when paper whose expansion and contraction is not sufficiently small is used as the printing sheet 2, the paper expands and contracts, leading to quality deterioration of the three-dimensional decoration effect. Therefore, only paper satisfying the conditions corresponding to the printing accuracy can be used as the material for the printing sheet 2.

  Further, the pressure-sensitive adhesive 3 for adhering the printing sheet 2 to the transparent resin film 4 does not require heating to the thermocompression bonding temperature and pressurization to the thermocompression bonding pressure as in the hot press process, and can be performed at room temperature or as required. Those that can be adhered under temperature are used.

  The three-dimensional decorative sheet 1 having the above structure can be used as a product as it is. For example, it can be used as a calendar, business card, album, poster, guide letter, greeting card. The three-dimensional decorative sheet 1 can also be used as a product material. For example, a container can be manufactured using the three-dimensional decorative sheet 1.

  Furthermore, the three-dimensional decorative sheet 1 can be attached to any other object to be decorated. In this case, an adhesive may be applied to the printing sheet 2, but the release paper 2 </ b> C may be peeled off using the sealing sheet 2 </ b> A as the printing sheet 2 and attached to the object to be decorated.

  If the three-dimensional decoration sheet 1 is attached to the object to be decorated via the adhesive 3, a three-dimensional decoration effect can be created on the object to be decorated. Moreover, even if the three-dimensional decorative sheet 1 is once attached to the object to be decorated, it can be easily peeled off when it becomes necessary to remove it later. If a flexible material is used as the printing sheet 2, the three-dimensional decorative sheet 1 can be easily attached to an object to be decorated having various complicated shapes. That is, it is possible to apply a three-dimensional decoration on an object to be decorated with various materials and shapes.

  FIG. 4 is a structural diagram of a three-dimensional ornament using the three-dimensional ornament sheet 1 shown in FIG.

  As shown in FIG. 4, the three-dimensional decorative object 12 can be configured by sticking the three-dimensional decorative sheet 1 shown in FIG. 1 to the object to be decorated 11 with an adhesive or a pressure-sensitive adhesive 10. Any object can be used as the decoration object 11 as long as the three-dimensional decoration sheet 1 can be attached. For example, a three-dimensional decoration is obtained by sticking the three-dimensional decoration sheet 1 to a decoration object 11 such as a metal, a resin product, a glass product, a can, a box such as a paper box or a wooden box, a bottle, a plastic bottle, a container, or an automobile body. The object 12 can be configured.

  Next, a method for manufacturing the three-dimensional decorative sheet 1 and the three-dimensional decorative object 12 will be described.

  FIG. 5 is a flowchart showing a method of manufacturing the three-dimensional decorative sheet 1 shown in FIG. 1 and the three-dimensional decorative object shown in FIG. 4, and the reference numerals with numerals in the figure indicate the steps of the flowchart.

  First, in step S <b> 1, printing is performed on the surface of the printing sheet 2 at the first pattern pitch, and the printing layer 5 is formed on the surface of the printing sheet 2.

  Next, in step S2, the surface of the transparent resin film 4 on which the plurality of lenses 4A have already been formed with a second pattern pitch different from the first pattern pitch, at a room temperature or appropriate adhesive The pressure-sensitive adhesive 3 is applied at a temperature.

  Next, in step S3, the printing layer 5 side of the printing sheet 2 is adhered to the adhesive 3 on the transparent resin film 4 at room temperature or at an appropriate adhesion temperature.

  In addition, the adhesive 3 may be apply | coated to the surface side of the printing sheet 2 in which the printing layer 5 was formed, and the transparent resin film 4 may be adhered to the adhesive 3 on the printing sheet 2. FIG. However, it is desirable to apply the adhesive 3 to the transparent resin film 4 side from the viewpoint of maintaining the quality of the printing sheet 2 well.

  In this way, the three-dimensional decorative sheet 1 is manufactured. When manufacturing the three-dimensional decoration 12, the three-dimensional decoration sheet 1 is affixed to the to-be-decorated object 11 via the adhesive agent or the adhesive 10 in step S4 implemented after step S3. The three-dimensional ornament 12 can be produced by such a method for producing the three-dimensional ornament 12. However, as described above, a three-dimensional decorative object can also be manufactured using the three-dimensional decorative sheet 1 as a raw material.

  FIG. 6 is an enlarged cross-sectional view showing an example of a container-shaped three-dimensional decorative object created using the three-dimensional decorative sheet 1 shown in FIG. 1 as a material.

  The three-dimensional ornament 12A is a box-shaped container created by bending the three-dimensional ornament sheet 1. The shape of the container may be either a round box shape or a square box shape. One edge of the three-dimensional decorative sheet 1 is provided with a margin portion 20 that is not covered with the transparent resin film 4 and from which the printing sheet 2 is exposed. Then, the printing sheet 2 side at the other end of the three-dimensional decorative sheet 1 of the glue margin 20 is bonded to the printing sheet 2 at the other end of the three-dimensional decorative sheet 1 via an adhesive or pressure-sensitive adhesive 10. Sticky.

  However, the adhesive sheet or adhesive 10 having a sufficiently strong adhesive force or adhesive force is applied to the surface end of the transparent resin film 4 without providing the adhesive margin 20 on the three-dimensional decorative sheet 1, and the facing printing sheet. You may make it adhere | attach or stick to 2 edge part.

  Further, when it is desired to make the edge portion 21 of the three-dimensional decorative object 12A, which is a box-shaped container, have a sharp angle, the transparent resin film 4 may not be bent to a desired angle due to properties such as elasticity of the transparent resin film 4. is there. In such a case, the cut portion 22 is provided in the transparent resin film 4 as necessary, and the printing sheet 2 is bent at a desired angle by removing or reducing the properties such as elasticity of the transparent resin film 4. It is done. Note that the transparent resin film 4 does not necessarily have to be completely cut at the cut portion 22 as shown in FIG. 6, and only the cut is made so that the transparent resin film 4 can be bent to a desired angle. Good.

  With the three-dimensional decoration 12A as a container configured as described above, a three-dimensional decoration effect can be created on the surface of the container.

  FIG. 7 is an enlarged cross-sectional view showing another example of a container-shaped three-dimensional decorative object created using the three-dimensional decorative sheet 1 shown in FIG. 1 as a material.

  The three-dimensional ornament 12B is a container having a cylindrical lid-side container 30 whose one end is closed and a cylindrical bottom-side container 31 whose one end is closed. In the example shown in FIG. 7, the surface on the closed end side of the lid-side container 30, that is, the material of the lid 30 </ b> A is the three-dimensional decorative sheet 1. The outer surface side of the lid 30A is set to the lens 4A side of the transparent resin film 4 so that a three-dimensional decoration effect can be obtained when the three-dimensional decoration 12B as a container is viewed from the outside.

  The end portion on the lid 30A side of the cylindrical member 30B of the lid-side container 30 is bent inside (curled). And the edge part of the three-dimensional decoration sheet 1 is adhere | attached or adhere | attached on the bent part of the cylindrical member 30B via the adhesive agent or the adhesive 10. FIG. Note that the three-dimensional decorative sheet 1 constituting the lid 30A may be merely fitted into the cylindrical member 30B without applying the adhesive or the pressure-sensitive adhesive 10 to the three-dimensional decorative sheet 1.

  In the three-dimensional decoration 12B as a container configured as described above, a three-dimensional decoration effect can be created only in a required portion of the container.

  Next, a method for manufacturing the three-dimensional ornament 12A shown in FIG. 6 will be described.

  FIG. 8 is a flowchart showing an example of a method for manufacturing a container having the same structure as that of the three-dimensional decorative object 12A shown in FIG. 6, and the reference numerals with numerals in the figure indicate each step of the flowchart.

  First, in step S <b> 10, printing is performed on the surface of the printing sheet 2 at the first pattern pitch, and the printing layer 5 is formed on the surface of the printing sheet 2. In FIG. 8, a dotted line is a folding line that is bent when the container is assembled.

  Next, when the margin part 20 is provided in the three-dimensional decorative sheet 1 in step S11, the part to be the margin part 20 on the printing layer 5 side of the printing sheet 2 is masked. For example, the margin portion 20 is covered with a mask paper 40 having a predetermined size.

  Next, in Step S12, the surface of the transparent resin film 4 on which the plurality of lenses 4A are already formed with the second pattern pitch different from the first pattern pitch is not room temperature or appropriate adhesive. The pressure-sensitive adhesive 3 is applied at a temperature. However, the pressure-sensitive adhesive 3 may be applied to the surface of the printing sheet 2 on which the printing layer 5 is formed at room temperature or under an appropriate pressure-sensitive adhesive temperature.

  Next, in step S <b> 13, the printing layer 5 side of the printing sheet 2 is adhered to the adhesive 3 on the transparent resin film 4 at normal temperature or at an appropriate adhesion temperature. As a result, the three-dimensional decorative sheet 1 that is a material of the three-dimensional decorative object 12A that is a container is manufactured.

  Next, in step S14, the three-dimensional decorative sheet 1 is cut into a developed view shape of the container.

  Next, in step S15, the transparent resin film 4 in the masked portion is cut. That is, the mask paper 40 to which the transparent resin film 4 is adhered via the adhesive 3 is cut. Thereby, the margin part 20 is exposed.

  Next, in step S <b> 16, a cut is made in the folding line in the three-dimensional decorative sheet 1 in the shape of the developed container, and the cut portion 22 is formed.

  Next, in step S <b> 17, the adhesive or pressure-sensitive adhesive 10 is applied to the glue margin 20.

  Next, in step S <b> 18, the three-dimensional decorative sheet 1 is folded at the cut portion 22, and the adhesive margin 20 is adhered or adhered to the surface of the opposing three-dimensional decorative sheet 1 through the adhesive or the adhesive 10. As a result, a container is formed.

  In addition, when the paste margin part 20 and the notch part 22 are not provided, when it is not necessary to cut | disconnect the three-dimensional decoration sheet 1 in the expanded view shape of a container, a related process can be skipped. Further, the order of the steps may be changed within a possible range. That is, the step of providing the margin portion 20 and the step of providing the cut portion 22 are performed as necessary.

  The margin portion 20 can be provided by, for example, masking the printed printing sheet 2 with a mask material such as the mask paper 40. However, the transparent resin film 4 can be used without using the mask material. Alternatively, the margin part 20 may be formed by peeling from the printing layer 5 side.
