Description

  The present invention relates to a transfer sheet for applying a decorative pattern by thermocompression bonding to the surface of various transfer objects (hereinafter referred to as “transfer material”) such as paper, cloth, synthetic resin, ceramics, etc. The present invention relates to a manufacturing method and a decorative molded product using a transfer sheet.

  2. Description of the Related Art Conventionally, a decorative pattern formed by, for example, a metal thin film has been formed on the surface of a material to be transferred by pressure-bonding a transfer sheet to the material to be transferred such as paper or cloth. As shown in FIG. 17, the existing general transfer sheet 100 is disposed on the entire surface of the colorless and transparent film sheet 101 through a transparent release agent layer 102 so that the film sheet 101 can be peeled off. The metal film layer 103 formed by laminating metals in a thin film shape by, for example, vacuum deposition is formed. Hereinafter, the release agent layer 102 and the metal film layer 103 are collectively referred to as a “transfer layer 104”.

  In order to form a desired decorative pattern on the surface of the transfer material using this transfer sheet 100, first, as shown in FIGS. 18 (1) to (3), a metal thin film on the surface of the transfer material 105 is used. An adhesive that adheres at room temperature or a heat-sealable adhesive 106 that does not cause adhesiveness at room temperature is applied to a predetermined portion that forms the decorative pattern (FIG. 18A). Next, the transfer sheet 100 is superimposed on the transfer material 105, and the transfer sheet 100 is pressure-bonded to the transfer material 105 by applying heat and pressure or only pressure from above the transfer sheet 100 (FIG. 18 (2)). )). Thereafter, when the transfer sheet 100 is peeled off from the transfer material 105, the film sheet 101 and the release agent layer 102 are peeled off at the portion where the adhesive 106 of the transfer material 105 is applied (FIG. 18 (3)). Then, the transfer layer 104 of the transfer sheet 100 is transferred to the surface of the transfer material 105 to form a decorative pattern formed by a metal thin film (see, for example, Patent Document 1).

JP 2005-88304 A

In the above-described existing transfer sheet 100, it is possible to form a decorative pattern (hereinafter referred to as "metal pattern") made of a metal thin film by partially transferring the metal film layer 103 onto the transfer material 105. However, in order to form a desired metal pattern on the transfer material 105, an adhesive 106 is applied to form a metal pattern area on the surface of the transfer material 105 each time the transfer sheet 100 is pressure-bonded. It is necessary to do it, and the work is troublesome.
In addition to this metal pattern, in order to form a certain pattern (for example, a color pattern using color ink) on the transfer material 105, the other material 107 of the transfer material 105 where the metal pattern is not formed is previously (or After the fact) it is necessary to form a color pattern by printing the pattern with color ink. However, if the formation of the color pattern on the intended surface of the transfer material 105 fails, the entire transfer material 105 must be discarded, resulting in a disadvantage that the yield decreases.

  The present invention has been made paying attention to the above-mentioned problems, a transfer sheet capable of easily forming various decorative patterns on the surface of a transfer material without failure, and a method for producing the transfer sheet, It is an object to provide a decorative molded product using the transfer sheet.

  The transfer sheet according to the present invention is for obtaining a decorative pattern composed of a main pattern formed by a metal or pigment thin film by thermocompression bonding, and is provided on a transparent film sheet having releasability. A pattern layer for obtaining the main pattern is formed by attaching a metal or a pigment in a thin film form through the layer, and is bonded so as to cover the pattern layer and the area where the film sheet without the pattern layer is exposed. A layer of agent is formed.

  In the transfer sheet having the above-described configuration, the “adhesive” is used for bonding and fixing the pattern layer of the transfer sheet to the surface of the transfer material during thermocompression bonding. In order to prevent sticking, it is desirable that the adhesive does not generate adhesiveness at room temperature and melts when heated to exhibit adhesiveness. In order to form a decorative pattern on the surface of a material to be transferred such as paper using this transfer sheet, first, the transfer sheet is superposed on the material to be transferred so that the pattern layer faces the surface of the material to be transferred. Next, when heat and pressure are applied from above and the transfer sheet is thermocompression bonded to the surface of the transfer material, the pattern layer of the transfer sheet is transferred to the surface of the transfer material. After that, when the transfer sheet is peeled off from the transfer material, the film sheet is peeled off due to the release agent layer and the release property of the film sheet, and a decorative pattern consisting of a main pattern formed in a predetermined shape on the surface of the transfer material Is formed.

  According to the transfer sheet having the above-described configuration, the transfer sheet is formed with a pattern layer for obtaining a main pattern formed in a predetermined shape. As a result, a decorative pattern with excellent design can be easily formed on the surface of the transfer material without failure. Further, by cutting the transfer sheet into an appropriate size and shape, a desired product, a sample, or a design can be created using the transfer sheet.

  In a preferred embodiment of the present invention, the adhesive contains a pigment and is colored. According to this embodiment, a color is applied to the region where the main pattern of the transfer material does not exist by the adhesive colored with the pigment. It becomes more convenient to use this colored transfer sheet for the creation of products and designs.

  In another transfer sheet according to the present invention, a decorative pattern comprising a main pattern formed by a thin film of metal or pigment and a color pattern formed by filling a non-patterned area other than the main pattern with a pigment is formed by thermocompression bonding. A first film for obtaining the main pattern by depositing a metal or a pigment in a thin film form on a transparent film sheet having releasability via a layer of a transparent release agent. A pattern layer is formed, and a second pattern layer for obtaining the color pattern by attaching a pigment is formed on a region of the film sheet where the first pattern layer is not present, and the first pattern layer An adhesive layer is formed so as to cover the first pattern layer and the second pattern layer.

  In the transfer sheet having the above-described configuration, the adhesive does not cause adhesion at room temperature so that the sheets do not stick to each other even when a plurality of transfer sheets are stacked, and melts when heated to exhibit adhesion. Desirably, it is a heat-fusible adhesive. In order to form a decorative pattern on the surface of a transfer material such as paper using this transfer sheet, first, the transfer sheet is covered so that the first and second pattern layers face the surface of the transfer material. Overlay the transfer material. Next, when heat and pressure are applied from above and the transfer sheet is thermocompression bonded to the surface of the transfer material, each pattern layer of the transfer sheet is transferred to the surface of the transfer material. After that, when the transfer sheet is peeled off from the transfer material, the film sheet peels off due to the release agent layer and the release property of the film sheet, and various decorations that combine the main pattern and the color pattern on the surface of the transfer material A pattern is formed.

  According to the transfer sheet having the above-described configuration, the first pattern layer for obtaining the main pattern and the second pattern layer for obtaining the color pattern in the area where the first pattern layer does not exist on one transfer sheet. Therefore, a decorative pattern composed of various patterns can be easily formed on the surface of the material to be transferred only by performing a simple transfer operation conventionally used. Moreover, since the decorative pattern can be formed on the transfer material without failure, a transfer material to which various patterns are added can be obtained with high yield.

  In a preferred embodiment of the present invention, a transparent adhesive intermediate layer is provided on the exposed area of the film sheet where the first pattern layer and the first pattern layer are not present on the film sheet. The second pattern layer is formed on the film sheet via an adhesive intermediate layer. Note that the adhesive forming the intermediate layer of the adhesive is also preferably a heat-fusible adhesive that does not exhibit adhesiveness at room temperature and melts and exhibits adhesiveness when heated.

  According to the transfer sheet manufacturing method of the present invention, a decorative pattern comprising a main pattern formed by a thin film of metal or pigment and a color pattern formed by filling a non-patterned area other than the main pattern with a pigment is thermocompression bonded. A sheet material obtained by attaching a metal or a pigment in a thin film form to a whole surface of a transparent film sheet through a transparent release agent layer, and A preparation process for preparing a sheet-shaped mold material on which an original image for forming a pattern area is drawn, and the sheet material and the mold material are overlapped, and a thin film of metal or pigment is thermocompression bonded to the mold material along the original image of the mold material.

It is.

  In the above-described configuration of the present invention, as the sheet material, an existing transfer sheet that is generally commercially available, for example, a metal or pigment through a layer of a transparent release agent on the entire surface of a film sheet having releasability. What formed the thin film can be used. In addition, paper is usually used as the mold material, but the present invention is not limited to this, and a thin plate material such as wood, cloth, leather, or synthetic resin can be used as long as it is a sheet.

  According to the transfer sheet manufacturing method of the present invention, a transfer sheet on which a first pattern layer and a second pattern layer are formed can be easily manufactured using an existing transfer sheet as it is. Furthermore, since the pattern is formed on the original image portion of the mold material, for example, by attaching a thin film of metal or pigment, the mold material itself can also be used for other specific applications without leaving an existing transfer sheet. Can be used.

In a preferred embodiment of the present invention, in the preparation step, a paper pattern on which an original image by a toner is represented is prepared as a mold material, and in the first pattern forming step, a metal or pigment thin film of a sheet material is used as the original image of the paper pattern. A first pattern layer for obtaining a main pattern is formed on the film sheet of the sheet material by thermocompression bonding with the toner as a binder on the film and cutting out along the original image.
In this embodiment, first, an original is drawn on an arbitrary material such as paper or synthetic resin by handwriting or other methods to produce an original, and the original is copied using a copying machine using toner. Produce a pattern with the original picture. The sheet material thus obtained is superimposed on the sheet material, and the sheet material metal or pigment thin film is transferred onto the original pattern paper image by hot stamping using toner as a binder (adhesive) to form a sheet material metal or pigment thin film. The first pattern layer for obtaining the main pattern is formed on the film sheet of the sheet material. According to this embodiment, it is possible to produce a template as a mold material easily and inexpensively without using a special template.
In this embodiment, the material of the paper pattern is not particularly limited, but a resin film or the like can be used in addition to a normal paper material such as Japanese paper or Western paper. The thickness of the pattern is such that it can be manually fed if it is manually fed into a copying machine, for example.
The type of the copying machine is not limited as long as it is a model using toner that can be used as a thermocompression binder (for example, a copying machine manufactured by Fuji Xerox Co., Ltd. or a copying machine manufactured by Canon Inc.). When the original drawing is produced by a computer, the image data of the original drawing is stored in a storage medium such as a hard disk or a CD-ROM. By sending the image data to the copying machine and printing it, a pattern paper as a template is obtained. Obtainable.

  In a preferred embodiment of the present invention, the first pattern layer of the sheet material and the region where the film sheet without the first pattern layer is exposed are covered between the first pattern forming step and the coloring step. And a transparent adhesive is applied to form an intermediate layer of the adhesive. According to this embodiment, when the second pattern layer is formed on the film sheet by, for example, manually applying color ink containing a pigment, the surface is smooth when the color ink is directly applied to the film sheet. Although it is difficult to apply, if the intermediate layer of the adhesive is formed on the entire surface of the film sheet, the color ink can be easily applied, so that the second pattern layer can be formed accurately and easily. Moreover, it can also prevent that each pattern layer peels from a film sheet, and when conveying a transfer sheet, it can prevent that a transfer sheet is damaged by peeling each pattern layer from a film sheet.

  In the decorative molded product according to the present invention, the pattern layer of the transfer sheet according to the present invention is transferred onto one surface of a resin molded product made of a transparent resin. Thereby, the pattern layer of a transfer sheet can be seen through a transparent resin molding, and the decorative molded product to which various decorative patterns were given can be provided. The pattern layer of the transfer sheet is transferred to the resin molded body by thermocompression bonding or resin adhesive force.

According to the transfer sheet of the present invention, since the pattern layer for obtaining the main pattern is formed on the film sheet, the transfer material can be obtained simply by overlaying the transfer sheet on the transfer material. A decorative pattern with excellent design can be easily formed on the surface without failure.
According to another transfer sheet of the present invention, the first pattern layer for obtaining the main pattern and the second pattern for applying the color pattern to the area where the first pattern layer does not exist on the film sheet. Since a single layer is formed, a simple transfer operation is performed once using this single transfer sheet, and various decorative patterns composed of a main pattern and a color pattern fail on the surface of the transfer material. And can be formed accurately and easily.
Furthermore, according to the manufacturing method of the present invention, the transfer sheet of the present invention can be manufactured by using an existing transfer sheet (for example, metal vapor deposition transfer foil, pigment transfer foil, etc.) as it is, and various patterns can be easily obtained. Can be produced.
Furthermore, since the transfer sheet according to the present invention is manufactured using the existing transfer sheet as it is, it is not necessary to prepare a separate film sheet, and the cost can be reduced.

  5 to 11 show specific examples of the manufacturing method of the transfer sheet 1 and the transfer sheet 10 described above. First, as a preparation step, as shown in FIG. 5, a sheet material 14 and a sheet-like mold material (pattern paper) 15 are prepared. In this embodiment, as the sheet material 14, an existing transfer sheet that is generally commercially available is used as it is, and the transfer sheet 1 and the transfer sheet 10 according to the present invention are manufactured. The sheet material 14 has a metal film layer 24 made of a metal thin film formed on a whole surface on one surface of a transparent film sheet 2 having releasability via a layer 23 of a transparent release agent. Etc. are formed.

  As shown in FIG. 6, the mold material 15 has an original image 16 that forms a non-pattern area other than the main pattern 21 (in this embodiment, a double ring pattern) on the surface of a paper material. A contour 25 of the main pattern 21 (double ring pattern) is formed in an area where the original image is not represented. The bonding layer 17 can also be formed by applying an adhesive having heat-fusibility to the portion of the original image 16 by silk screen printing, but in this embodiment, it can be used as a binder for thermocompression bonding. By copying a paper (original drawing) on which an original image is drawn using a copying machine using a proper toner, a pattern paper on which the original image by the toner is expressed is obtained. Since the original toner melts by heat and functions as the bonding layer 17, this pattern paper is used as the mold material 15.

  Next, as shown in FIG. 7, the sheet material 14 is superimposed on the surface of the mold material 15 and pressed from above with a heat transfer machine using a heat roller, a flat plate type or the like, whereby the metal thin film 24 of the sheet material 14 is coated with toner. As a binder, it is transferred onto the original image of the mold material 15 by thermocompression bonding. Then, when the sheet material 14 is peeled off from the mold material 15, the film sheet 2 of the sheet material 14 and the release agent layer 23 are separated, and the original image 16 of the mold material 15 is removed as shown in FIGS. The metal film layer 24 of the sheet material 14 adheres to the portion of the sheet material 14 together with the release agent layer 23, and the mold release from the sheet material 14 along the original image 16 of the mold material 15 as shown in FIGS. The agent layer 23 and the metal film layer 24 are cut out, and the pattern layer 4 for obtaining the region 12 where the film sheet 2 is exposed and the main pattern 21 on the film sheet 2 (in the second embodiment, the first pattern A sheet material 14 in which the layer 4) is partially formed is obtained.

  Next, as shown in FIG. 10, in the region 12 where the film sheet 2 between the pattern layer 4 (first pattern layer 4) and the pattern layer 4 (first pattern layer 4) of the sheet material 14 is exposed. If a heat-sealable adhesive is applied on the sheet material 14 to form an adhesive layer (adhesive layer 7 in the first embodiment) on the entire surface of the sheet material 14, the first layer shown in FIG. The transfer sheet 1 of one embodiment is obtained.

  In order to manufacture the transfer sheet 10 of the second embodiment, as shown in FIG. 11, the adhesive layer of the sheet material 14 that has undergone the above-described adhesive application step (in the second embodiment, the intermediate adhesive layer 5). Color ink is applied thereon to form the second pattern layer 6. In this embodiment, the color scheme is changed for each region 13A, 13B, 13C on the intermediate adhesive layer 5 corresponding to each region 12 where the film sheet 2 is exposed. For example, yellow color ink is used for the region 13A, Blue color ink is applied to the region 13B, and red color ink is applied to the region 13C. Thereby, the 2nd pattern layer 6A, 6B, 6C colored with the predetermined color is formed on the area | region 12 where the film sheet 2 in which the 1st pattern layer 4 of the sheet | seat material 14 does not exist is exposed.

  Finally, an adhesive layer 7 is formed on the intermediate adhesive layer 5 and the second patterned layer 6 by thinly applying a colorless and transparent adhesive having a heat-sealing property so as to cover them. The transfer sheet 10 of the second embodiment shown in FIG. As an adhesive for forming the adhesive layer 7, it is preferable to use an adhesive having a stronger adhesive strength than the adhesive used for forming the intermediate adhesive layer 5.

  In addition, about the transfer sheet 10 of 2nd Example, it is not necessarily required to provide the intermediate | middle adhesive layer 5, The film without the 1st pattern layer 4 of the sheet | seat material 14 which passed through the 1st pattern formation process shown in FIG. The second pattern layer 6 may be formed on the film sheet 2 by directly applying color ink onto the region 12 where the sheet 2 is exposed. When the adhesive layer (intermediate adhesive layer 5) is formed on the entire surface of the film sheet 2, there is an advantage that the color ink can be easily applied and the second pattern layer 6 can be formed accurately and easily. In addition, when the adhesion of the color ink to the film sheet is weak, there is also an advantage that it is possible to prevent delamination of the color ink from the film sheet.

In order to form the decorative pattern 20 on the surface of the transfer material 18 such as paper using the transfer sheet 10 having the above-described configuration, first, as shown in FIG. The transfer sheet 10 is superimposed on the transfer material 18 so as to face the surface of the sheet, and heat and pressure are applied to the transfer sheet 10 from above using a heat transfer machine such as a heat roller or a flat plate, for example. The material to be transferred 18 is thermocompression bonded (FIG. 12 (2)). Thereafter, when the transfer sheet 10 is peeled off from the transfer material 18, the film sheet 2 of the transfer sheet 10 is peeled off due to the release property of the release layer 3 and the film sheet 2 (FIG. 12 (3)), and the transfer material 18 is transferred. The transfer layer 9 of the transfer sheet 10 is transferred to the surface. As a result, a variety of decorative patterns 20 are formed on the surface of the transfer material 18 by combining the main pattern 21 formed by the metal thin film and the color pattern 22 formed by the pigment.
Note that the pattern forming method using the transfer sheet 1 is the same as the above-described method, and thus the description thereof is omitted here.

  In the above embodiment, the transfer sheet 1 and the transfer sheet 10 according to the present invention are manufactured by using an existing transfer sheet 14 that is generally commercially available as it is. Since the metal layer is formed by adhering the film layer 24, the mold material 15 itself can also be used for other specific uses. For example, a decorative pattern can be obtained by coloring an area where the metal pattern of the mold material 15 is not formed with a paint, so that the pattern 15 can be used as a coloring picture. Therefore, the existing transfer sheet 14 can be used without surplus.

  In the above-described embodiment, the existing transfer sheet 14 is formed by forming a metal film layer on the film sheet 2 by vapor deposition or sputtering, but is not limited thereto, and gold, silver, copper The transfer sheet 1 and the transfer sheet 10 according to the present invention can be obtained by forming a hand foil obtained by manually thinning aluminum or an alloy thereof on a film sheet made of polypropylene resin or polyethylene resin. Can be manufactured.

  FIG. 13 shows a configuration of a decorative molded product 30 using the transfer sheet 10 shown in FIG. As shown in FIG. 14, this decorative molded product 30 is a colorless transparent or colored transparent melted in the mold 32 after a mold 32 having a predetermined shape is disposed on the adhesive layer 7 side of the transfer sheet 10. The transfer sheet 10 is adhered to the surface of the molten resin. Then, after the synthetic resin is solidified to form the resin molded body 31 having a predetermined shape, the film sheet 2 of the transfer sheet 10 is peeled off from the resin molded body 31 to cut off the excess portions, whereby each of the transfer sheet 10 A decorative molded product 30 with excellent design that allows the patterned layers 4 and 6 to be seen through the transparent resin molded body 31 is obtained. In order to solidify the synthetic resin, methods such as an oxygen bond type, a water bond type, a two-component reaction type, and a photocuring type can be used.

  FIG. 15 shows a configuration of a decorative molded product 33 of another example in which the transfer sheet 10 shown in FIG. 3 is used. This decorative molded product 33 is obtained by integrating a resin molded body 34 on the side opposite to the adhesive layer 7 of the transfer sheet 10. As shown in FIG. The pressure-sensitive adhesive sheet 36 having the pressure-sensitive adhesive surface 37 is superposed on the pressure-sensitive adhesive sheet 37, and heat and pressure are applied to the transfer sheet 10 from above using a thermal transfer machine, whereby the pressure-sensitive adhesive sheet 36 is thermocompression-bonded to the transfer sheet 10 (FIG. . Then, after the film sheet 2 of the transfer sheet 10 is peeled off, a mold 35 having a predetermined shape is disposed on the opposite side of the transfer sheet 10 from the adhesive layer 7 and is melted into the mold 35 to be colorless, transparent or colored. Then, the synthetic resin is poured and solidified, and the transfer layer 9 of the transfer sheet 10 is integrated with the resin molded body 34 (FIG. 16B). Thereafter, the pressure-sensitive adhesive sheet 36 is peeled off and an excess portion is cut, whereby the decorative molded product 33 with excellent design that allows the pattern layers 4 and 6 of the transfer sheet 10 to be seen through the transparent resin molded body 34 is obtained. can get.

In addition, the material of a synthetic resin is not specifically limited, Well-known resin, such as a polyester resin, an epoxy resin, a urethane resin, an acrylic resin, a photocuring resin, is used.
Moreover, the decoration molded product decorated using the transfer sheet 1 shown in FIG. 1 can also be manufactured by the method similar to the above.
