  According to this, since the color ink layer formed by ink jet printing expresses a color printing pattern, and the metal foil pattern layer expresses high brightness unique to the metal foil, the metal foil and high-definition color printing coexist. A transfer sheet excellent in design is realized. Furthermore, since the anchor effect between the ink sprayed by inkjet and the pinhole on the surface of the metal foil is improved and the adhesion is improved, a transfer sheet excellent in durability can be obtained.

  Here, a white layer formed on the color print layer between the color print layer and the base layer and sprayed with white ink having a droplet diameter of about 12 to 48 μm by an inkjet method. It is preferable to interpose a printing layer.

  According to this, since the white printing layer improves the color development of the color printing layer, the design decoration effect can be enhanced by making the printed pattern formed by the color printing layer appear more clearly.

  Further, a powder layer made of a powdery substance having an average particle size of 10 μm or less may be interposed between the seal mount and the protective coating layer.

  According to this, since the powder layer promotes irregular reflection of light, it is possible to produce high brightness unique to the metal foil, and to exhibit an excellent design decoration effect.

  In order to achieve the above object, a transfer sheet manufacturing method according to the present invention is a transfer sheet manufacturing method for transferring a pattern onto an adherend, and has flexibility and water-insolubility on a seal mount.

It is characterized by that.

  Thereby, the transfer sheet which made the outstanding design decoration effect as mentioned above and outstanding durability performance compatible can be manufactured.

  According to the transfer sheet of the present invention, a high-definition color printing pattern is expressed by forming a color printing layer by an ink jet method. Therefore, the design is achieved by the high brightness and high-definition color printing design unique to metal foil. A transfer sheet having excellent properties can be realized. In addition, since the anchor effect between the ink sprayed by inkjet and the pinhole on the surface of the metal foil is improved, a transfer sheet with enhanced adhesion and excellent durability can be realized.

  In addition, the transfer sheet manufacturing method according to the present invention makes it possible to manufacture a transfer sheet excellent in decorative effect and durability.

It is a partial top view of the transfer sheet which concerns on embodiment of this invention. It is a fragmentary sectional view in the AA line of FIG. It is a flowchart which shows the manufacture procedure of a transfer sheet. It is a partial top view of the transfer sheet which concerns on a modification.

  Hereinafter, a transfer sheet and a manufacturing method thereof according to the present invention will be described with reference to the drawings.

  FIG. 1 is a partial plan view of a transfer sheet according to Embodiment 1 of the present invention.

  The transfer sheet 1 covers a pattern formed using a metal foil made of a single metal such as gold, silver, platinum, copper tin, or aluminum or an alloy of these metals and a pattern formed using color printing. It is transferred to the sticking body to decorate the sticking body. FIG. 1 shows metal foil patterns 7a, 7b, and 7c of alphabets “A”, “B”, and “C” as examples of patterns by metal foil, and printed patterns 4a, 4b, as examples of patterns by color printing. 4c is shown.

  Human skin is typical of the transfer sheet 1 to be adhered, but nail seals used for nail art, etc. Tableware such as fingernails, nails, heavy boxes, chopsticks, spoons, etc. , Indirect dishes such as coasters and trays, ornaments such as flower arrangements and watches, stationery items such as pens and business card holders, furniture furnishings such as chests and folding screens, accessories such as hair ornaments and pendants, window glass, makeup Any article having a flat surface to which the transfer sheet 1 can be attached, such as a building such as a wall, can be an adherend.

  2 is a partial cross-sectional view taken along line AA in FIG.

  As shown in FIG. 2, the transfer sheet 1 includes a seal mount 2, a protective coating layer 3, a color printing layer 4, a white printing layer 5, a base layer 6, a metal foil pattern layer 7, an adhesive layer 8, and a silicon release paper 9. Are stacked.

  The seal mount 2 is a mount for holding the laminated protective coat layer 3 to the silicon release paper 9 until the transfer sheet 1 is attached to the adherend, and a conventional seal mount is used. be able to.

  The protective coating layer 3 is a thin layer of about 10 to 20 μm composed of a transparent resin film having flexibility and water insolubility, and protects the metal foil pattern layer 7 to enhance its wear resistance. At the same time, it is provided to enhance the flexibility of following the movement of the skin. Examples of the resin film constituting the protective coat layer 3 include acrylic, cellulose, butyral, urethane, and epoxy resin films.

  The color printing layer 4 is a layer formed by printing a pattern using full-color ink. The color printing layer 4 is formed by an ink jet method in which ink having a droplet diameter of about 12 to 48 μm is discharged and sprayed to be fixed. By adopting the ink jet method, it is possible to achieve fine halftone dots (dots) without crushing the ink, and it is possible to express a high-definition (1800 × 1800 dpi) printed pattern. In addition, by forming halftone dots, the ink droplets exhibit flexible elasticity and can follow the elasticity and expansion / contraction of the skin of the adherend. The ink used here is preferably a UV ink having flexibility. This is because the ink has flexibility so that it can follow the elasticity and expansion / contraction of the skin of the adherend.

  In addition, since the average diameter of fine holes (pinholes) on the surface of the metal foil constituting the metal foil picture layer 7 to be described later is about 13 μm, it is ejected by the ink jet method without crushing the ink having the above diameter. When sprayed, the anchor effect between the ink and the pinhole can be improved, the adhesion of the transfer sheet 1 can be improved, and a dramatic effect of durability can be realized.

  The white print layer 5 is a layer formed by printing with an ink jet method using a white ink in the same manner as the color print layer 4. The white print layer 5 improves the color of the color print layer 4 and is provided as necessary, for example, when the printed pattern formed by the color print layer 4 is more clearly reflected. On the contrary, it may be preferable not to provide it as in the case where the unique design of the metal foil pattern formed by the metal foil pattern layer 7 to be described later is emphasized.

  The underlayer 6 is a thin layer having a thickness of about 10 to 20 μm and is made of a transparent adhesive having the following composition. It forms so that it may become a pattern corresponding to the pattern form of the metal foil picture layer 7, and supports the metal foil of the metal foil picture layer 7.

(Composition of the pressure-sensitive adhesive of the underlayer 6)
Acrylic ester copolymer resin 20.0% by weight
Solvesso 150 (petroleum solvent, trade name) 48.0% by weight
Chelate-based crosslinking agent 2.0% by weight
Solfit (petroleum solvent, trade name) 30.0% by weight

  The metal foil pattern layer 7 is a layer made of a metal foil that is adhered to the base layer 6 and formed in a predetermined pattern form. The metal foil as used herein refers to a foil or sheet obtained by a foil-making method utilizing traditional craft technology, a foil or sheet obtained by industrial rolling technology such as a rolling roller, or a foil or sheet obtained by vapor deposition technology. Is included. In addition, it is preferable that the thickness of metal foil shall be the range of 0.1-5.0 micrometers. This is because an extremely thin metal foil of less than 0.1 μm is difficult to manufacture, and even if it can be manufactured, it lacks wear resistance. Further, the color of the human skin is transmitted through the metal foil, and the gloss generated by the metal foil is reduced, so that a design effect cannot be expected. On the other hand, a metal foil exceeding 5.0 μm is too thick and lacks flexibility, has poor followability to skin and is difficult to seal, and is economically disadvantageous.

  Explaining an example of forming the metal foil pattern layer 7 by the vapor deposition technique, the metal foil pattern layer 7 is lightly pressed by placing a 4.0 μm thick vapor deposition foil on the base layer 6 using a vacuum vapor deposition means. Thereafter, when the vapor-deposited foil is peeled off, the vapor-deposited foil remains adhered only to the portion where the underlayer 6 is formed, so that a desired picture form is formed.

  The pressure-sensitive adhesive layer 8 is a layer having a thickness of about 10 to 20 μm, and is a layer composed of a pressure-sensitive adhesive for attaching to an adherend such as a human skin. As an adhesive which comprises the adhesive layer 8, the thing of the following composition can be used, for example, However If it is a commercially available adhesive, it can be used almost. However, when the adherend is skin, it is needless to say that those having strong irritation are not suitable for use because they are in contact with the skin.

(Composition of the adhesive of the adhesive layer 8)
Acrylic ester resin 25.0% by weight
Methoxybutanol (solvent) 41.5% by weight
Chelate-based crosslinking agent 3.5% by weight
Diacetone alcohol 30.0% by weight

  The silicon release paper 9 is a sheet provided for preventing blocking, and a conventional one can be used.

  When the transfer sheet 1 configured as described above is applied to the skin of the upper arm of the human body, the silicone release paper 9 is first peeled, and then the adhesive layer 8 for application to the skin is pressed against the upper arm to seal Water is soaked in the sticker mount 2 from the back side of the mount 2. Then, after 20 to 40 seconds, the sticker mount 2 is easily removed and the pattern is transferred to the skin surface. If the excess glue or moisture is wiped off from the pattern with tissue paper or the like, the upper arm of the human body can be beautifully decorated with the metal foil of the metal foil pattern layer 7 and the color printing layer 4.

  Next, a method for manufacturing the transfer sheet 1 having such a configuration will be described.

  FIG. 3 is a flowchart showing a procedure for manufacturing the transfer sheet 1.

  First, paste-like starch is applied to the upper surface of the seal mount 2 and dried, and then the protective coat layer 3 is formed on the seal mount 2 by silk-screen printing the resin constituting the protective coat layer 3 (step) S10).

  Next, a high-definition full-color ink is ejected and sprayed on the formed protective coat layer 3 and fixed by printing, thereby forming the color printing layer 4 (step S20).

  Thereafter, when the white printing layer 5 is formed, the white printing layer 5 is formed by discharging and spraying high-definition white ink on the color printing layer 4 by an ink jet method (step S30).

  Subsequently, the transparent adhesive for supporting the metal foil described above is screen-printed on the white print layer 5 or on the color print layer 4 when the white print layer 5 is not formed, thereby forming a metal foil pattern. The underlayer 6 is formed with a corresponding pattern so that the layer 7 is formed in a desired pattern form (step S40).

  And after making the drying time (about 1 day) of the adhesive which comprises the base layer 6 similarly to the past, after putting metal foil on the base layer 6 and pressing lightly, peeling metal foil and metal foil The pattern layer 7 is formed (step S50).

  Finally, the adhesive layer 8 is formed by laminating an adhesive for adhering to the adherend on the metal foil pattern layer 7 so as to have the same pattern as the protective coat layer 3 by screen printing. Then, the transfer sheet 1 is completed by attaching the silicon release paper 9 for preventing blocking (step S60).

  The transfer sheet 1 manufactured in such a procedure expresses a high-definition color printing pattern by forming the color printing layer 4 by an ink jet method, and also includes the sprayed ink and the pinhole on the surface of the metal foil. Since the anchor effect is enhanced, the metal foil and the high-definition color printing design can coexist, and the adhesion can be enhanced to improve the durability.

  Subsequently, a modified example of the transfer sheet according to the first embodiment will be described.

  FIG. 4 is a partial plan view of a transfer sheet according to a modification.

  The transfer sheet 1a according to the modified example is different from the transfer sheet according to the embodiment in that a powder layer 10 is provided between the seal mount 2 and the protective coat layer 3.

  The powder layer 10 is a layer composed of a powdery substance (powder) having an average particle diameter of 10 μm or less, and is provided to increase the gloss of the metal foil forming the metal foil picture layer 7. The reason that the gloss of the metal foil is enhanced by the powder layer 10 is that the powdery substance promotes diffuse reflection of light. Moreover, the effect which prevents that the metal foil which comprises the metal foil picture layer 7 adheres to the sticker mount 2 by forming the powder layer 10 can also be expected. The powder layer 10 is formed by applying paste-like starch on the upper surface of the sticker mount 2 and drying it, followed by powdering.

  As the powdery substance constituting the powder layer 10, for example, baby powder mainly composed of talc can be used, and in addition, a powdery substance mainly composed of titanium oxide or the like can be used. .

  By providing the powder layer 10, the transfer sheet 1 a promotes diffused reflection of light, so that the gloss of the metal foil is further enhanced, combined with the decorative effect of color printing by the color printing layer 4. And can exhibit extremely high design properties.

  The powder layer 10 may be formed between the protective coating layer 3 and the color printing layer 4 from the viewpoint of increasing the gloss of the metal foil.

  However, by forming the powder layer 10 before the formation of the protective coating layer 3, that is, between the seal mount 2 and the protective coating layer 3 below the protective coating layer 3, the following effects can be obtained. .

  First, if the powder layer 10 is provided between the protective coating layer 3 and the color printing layer 4, the anchor effect between the sprayed ink and the pinhole of the metal foil may be hindered. The powder layer 10 is preferably a lower layer than the protective coat layer 3 in order to exhibit it.

  Further, in order to express the printed pattern by the color printing layer 4 more clearly, it is necessary to make the powder layer 10 as thin as possible and to make it with a small amount of powder. In this regard, if the powder is sprinkled after the formation of the protective coating layer 3, the amount of powder mixed into the protective coating layer 3 increases. The powder layer 10 can be formed with this powder. Furthermore, this also leads to an effect that it is possible to prevent extra foil or powder from adhering to the sticker mount 2.

  As described above, the transfer sheet according to the present invention has been described based on each embodiment. However, the present invention is not limited to these embodiments, and does not depart from the scope of the present invention. Needless to say, various variations or modifications are possible.

  For example, in each of the above embodiments, the protective coat layer is laminated on the seal mount. However, an adhesion preventing layer made of a resin having an adhesive property to the metal foil is interposed between the seal mount and the protective coat layer. It may be formed. Thereby, it can prevent effectively that the excess metal foil which generate | occur | produces during decoration of a metal foil picture layer combined with a powder layer adheres to a seal | sticker mount.

  In addition, the protective coating layer and the pressure-sensitive adhesive layer are laminated so as to be wider than the other layers, that is, the color printing layer, the white printing layer, the base layer, and the metal foil pattern layer. You may make it form wider than a layer. Thus, by making the protective coat layer and the pressure-sensitive adhesive layer wider than the other layers, the protective coat layer and the pressure-sensitive adhesive layer cover the other layers, so that the wear resistance of the metal foil is reduced. Thus, a transfer sheet having higher durability can be realized. Moreover, since the entire remaining layer is held by forming the pressure-sensitive adhesive layer wider than the protective coat layer, the durability can be further improved. Furthermore, since the pressure-sensitive adhesive layer becomes the widest, flexibility and flexibility can be improved, and a transfer sheet excellent in followability to the skin can be realized.

  The transfer sheet according to the present invention is useful as a sheet that enhances the decorative effect by transferring a pattern onto an adherend, and is particularly useful as a tattoo sheet that transfers the pattern onto the human skin.
