Hereinafter, a transfer sheet and a manufacturing method thereof according to the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a partial plan view of a transfer sheet according to Embodiment 1 of the present invention.
The transfer sheet 1 transfers a pattern formed by using a metal foil made of a single metal such as gold, silver, platinum, copper tin, or aluminum or an alloy of these metals to an adherend of the transfer sheet 1. The decoration of the adherend is intended. In FIG. 1, as an example of the pattern, alphabets “A”, “B”, and “C” patterns 6 a, 6 b, and 6 c are shown.
The body of the transfer sheet 1 is typically human skin, but tableware such as bowls and heavy boxes, chopsticks, tableware such as spoons, indirect tableware such as coasters and trays, flower arrangements, watches, etc. Transfer sheet 1 can be affixed to stationery items such as pens, business card holders, furniture furnishings such as chests and folding screens, accessories such as hair ornaments and pendants, buildings such as window glass and decorative walls Any article having a flat surface 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 has a configuration in which a sticker mount 2, a protective coating layer 3, a powder layer 4, a base layer 5, a metal foil picture layer 6, an adhesive layer 7, and a silicon release paper 8 are laminated. Have.
The seal mount 2 is a mount for holding the laminated protective coat layer 3 to the silicon release paper 8 until the transfer sheet 1 is attached to the adherend, and the conventional seal mount described above. Can be used.

  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 6 to enhance its wear resistance. At the same time, it is provided in order to enhance flexibility to follow 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 powder layer 4 is a layer composed of a powdery substance (powder) having an average particle size of 10 μm or less, and makes the durability of the protective coat layer 3 and the metal foil pattern layer 6 more robust, and the metal foil pattern layer. 6 is provided to increase the gloss of the metal foil forming 6. The reason why the gloss of the metal foil is enhanced by the powder layer 4 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 6 adheres to the sticker mount 2 by forming the powder layer 4 can also be expected. As will be described later, the powder layer 4 is preferably formed to a thickness of about 4 to 10 μm by powdering the protective coat layer 3 in a semi-dry state and mixing the powder into the protective coat layer 3. This is because if the powder layer 4 is too thin, the irregular reflection of light becomes insufficient, so that it is inferior in terms of the effect of enhancing the gloss of the metal foil, and if it is too thick, it becomes difficult to hold the underlying layer 5 to be laminated.
As the powdery substance constituting the powder layer 4, 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. .

The underlayer 5 is a layer having a thickness of about 10 to 20 μm, is composed of a transparent adhesive having the following composition, and is a layer provided to support the metal foil of the metal foil picture layer 6. The metal foil pattern layer 6 is formed to have a pattern corresponding to the pattern form.
(Composition of the pressure-sensitive adhesive of the underlayer 5)
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 6 is a layer made of metal foil that is adhered to the base layer 5 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.
An example of forming the metal foil picture layer 6 by vapor deposition technology will be described. The metal foil picture layer 6 is lightly pressed by placing a 4.0 μm thick vapor deposition foil on the underlayer 5 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 5 is formed, so that a desired pattern form is formed.

The pressure-sensitive adhesive layer 7 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 7, the thing of the following composition can be used, for example, However If it is a commercially available adhesive, it can use 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 7)
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 8 is a sheet provided for preventing blocking, and a conventional one can be used.
When the transfer sheet 1 configured in this way is applied to the skin of the upper arm of the human body, first the silicon release paper 8 is peeled off, and then the adhesive layer 7 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 6. At this time, since the powder layer 4 of the transfer sheet 1 promotes irregular reflection of light, it produces high brightness unique to the metal foil and exhibits an excellent design decoration effect.

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, after the formed protective coat layer 3 is in a dry and hardened state, that is, in a semi-dry state, the above-mentioned powder is sprinkled to form the powder layer 4 (step S20). When a base layer is laminated on a protective coat layer as in the prior art, a considerable amount of time must be taken until the protective coat layer is completely dried in order to form the base layer with an adhesive. In this respect, if the powder forms a powder layer, it can be powdered even in a semi-dry state because it is in a powder form, and the density is obtained by mixing the powder into the semi-dry protective coat layer 3. As a result, the robustness and durability of the protective coating layer 3 as a protective film are improved. In addition, it takes about 30 minutes to 2 hours at room temperature (15 to 25 ° C.) for the protective coat layer 3 to be in a semi-dry state.
Subsequently, on the powder layer 4, the transparent adhesive for supporting the metal foil described above is screen-printed to form the base layer 5 in a corresponding pattern so that the metal foil picture layer 6 is formed in a desired picture form. Form (step S30).
And after making the drying time (about 1 day) of the adhesive which comprises the base layer 5 similarly to the past, after placing metal foil on the base layer 5 and pressing lightly, peeling metal foil and removing metal foil The pattern layer 6 is formed (step S40).
Finally, an adhesive for adhering to the adherend is laminated on the metal foil pattern layer 6 so as to have the same pattern as the protective coating layer 3 by screen printing to form the adhesive layer 7. Then, the transfer sheet 1 is completed by attaching the silicon release paper 8 for blocking prevention (step S50).

  By manufacturing the transfer sheet 1 according to the above-described procedure, it is not necessary to wait for the protective coat layer 3 to be completely dried before forming the powder layer 4. The time required to form the film is extremely shorter than the drying waiting time (one day or longer) of the conventional protective coating layer 3, and the lead time can be significantly shortened.

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 modification is different from the transfer sheet 1 of the first embodiment in that the powder layer 4a is formed so as to cover the protective coat layer 3.
Thus, by covering the protective coating layer 3 with the powder layer 4a, it becomes possible to improve the durability and the stability of the quality of the protective coating layer 3, and the brightness of the metal foil can be further enhanced.

(Embodiment 2)
Next, a transfer sheet according to Embodiment 2 of the present invention will be described.
FIG. 5 is a partial plan view of the transfer sheet according to the second embodiment.
The transfer sheet 11 according to the second embodiment is laminated so that the protective coat layer 13 and the pressure-sensitive adhesive layer 17 are wider than the other layers, that is, the powder layer 14, the base layer 15, and the metal foil pattern layer 16. Furthermore, it differs from the transfer sheet 1 according to Embodiment 1 in that the pressure-sensitive adhesive layer 17 is formed wider than the protective coating layer 13.

  Thus, by making the protective coat layer 13 and the pressure-sensitive adhesive layer 17 wider than the other layers, the protective coat layer 13 and the pressure-sensitive adhesive layer 17 are covered with the other layers sandwiched between them. A transfer sheet with improved wear resistance and higher durability can be realized. Moreover, since the entire remaining layer is held by forming the pressure-sensitive adhesive layer 17 wider than the protective coating layer 13, the durability can be further improved. Furthermore, since the pressure-sensitive adhesive layer 17 is the widest, flexibility and flexibility can be improved, and a transfer sheet excellent in followability to the skin can be realized.

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.

  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.
