Description

Description: TECHNICAL FIELD The present invention relates to a transfer sheet and a method for decorating an article using the transfer sheet, and more specifically, a heat transfer dye (sublimation dye) is used to form an arbitrary image. It is intended to provide a transfer sheet capable of forming a sheet, and capable of adhering or transferring the formed image to an arbitrary article, and a decoration method using the transfer sheet.

(Conventional technology) Conventionally, thermal transfer (sublimation transfer) of cloth with a heat transferable dye
The method has been used for a long time, and this method forms a dye pattern layer carrying a heat transferable dye on a sheet-shaped substrate, superimposes this on a cloth, and heats it to transfer the dye to the cloth to heat the cloth. It is a method of forming an image on the. Utilizing this technology, coupled with the recent development of precision image technology such as a thermal printer, various precision image forming methods have been proposed on a plastic film from a thermal transfer sheet having a heat transferable dye, which is comparable to a photograph. ing.

According to this recent method, for example, a camera, an image, a television image or a graphic image of a personal computer can be easily made into a hard copy on the surface of a transfer material such as paper having a polyester layer. It has reached a level where it can fully compete with technology and precision printing technology.

(Problems to be Solved by the Invention) Although the thermal transfer technique as described above has an advantage that an arbitrary image can be easily formed, the transferred article is made into a material that can be dyed with a heat transferable dye such as polyester. On the other hand, the transferred article is limited in shape to a sheet-like material such as a film or a sheet, and forms an image on wood, metal, glass, ceramics, etc. In addition, even in the case of plastics such as polyester, the three-dimensional molded article other than the sheet-shaped article even if the image forming surface thereof is a curved surface, has an uneven shape, or is flat. Has a problem that it is difficult to form an image.

In particular, as the fields of use of various cards such as cash cards have expanded in recent years, it is necessary to add images and symbols to these cards to give them various functions and decorations. However, it is difficult to apply an image to these cards by the above-mentioned thermal transfer method because they are inflexible or have irregularities such as letters and symbols.

As a method of solving such a drawback, there is a method of sticking a picture sticker having a desired image on a desired place of a desired article, but since the sealing material is relatively thick in this method,
There are drawbacks that the sticking portion is projected, the seal and the article to be decorated do not have a sense of unity, and are easily peeled off.

As a method that does not cause such a defect, there is a method using a thermal transfer method such as a hot stamp method.
This method has a drawback that a heating means is always required at the time of image transfer, and there is a problem that thermal transfer is difficult on a complicated uneven surface as in the above case.

Therefore, there is a demand for the development of a technique in which a desired image can be easily provided on the surface of an article made of an arbitrary material and having an arbitrary shape and an arbitrary surface shape, and the image and the article to be decorated are integrated. Has been done.

(Means for Solving Problems) That is, according to the present invention, a thermal transfer sheet comprising a layer having a sublimable dye provided on a sheet-shaped substrate, and an image receiving layer provided on the sheet-shaped substrate A transfer sheet for forming an image on the image receiving layer by heating the sheet with a thermal head that operates according to image data, with a weak adhesive layer on one surface of the sheet-shaped substrate. And a method for decorating an article using the transfer-receiving sheet, wherein the transfer-receiving sheet is provided with a removable image-receiving layer.

The present invention will now be described in more detail with reference to the accompanying drawings, which schematically show embodiments of the present invention.

FIG. 1 is a diagram schematically showing a basic aspect of a transfer sheet 10 of the present invention, and FIGS. 2 to 3 are diagrams showing a preferred embodiment of the transfer sheet of the present invention.

As shown in the first drawing, the basic structure of the transfer sheet 10 of the present invention has a weak adhesive layer 2 on one surface of an arbitrary sheet-shaped substrate 1.
The image receiving layer 3 which can be peeled off is provided. By configuring the transfer-receiving sheet of the present invention as described above, a desired forward or reverse image is formed on the image-receiving layer 3 by the thermal transfer sheet having the heat transferable dye, and then the image-receiving layer 3 having the image is formed into a sheet shape. By peeling from the base material 1 and sticking it to any article by any means, or sticking without peeling, and then peeling the base material sheet, the above-mentioned drawbacks of the prior art are eliminated. It is basically solved.

That is, the image receiving layer 3 in the above is limited to a material that can be dyed with a heat transferable dye, but the image formed and peeled or transferred from the sheet-shaped substrate 1 depends on the material of the article to be decorated. Depending on the bonding method, glass, metal, wood, or even plastics materials that are difficult to dye with heat transfer dyes can be freely attached or transferred.

Further, since the image receiving layer 3 having an image and peeled or transferred from the sheet-shaped substrate 1 is very thin and has sufficient flexibility, even if the surface shape of the article to be decorated is a curved surface or an uneven surface, those Since the surface shape of the article can be sufficiently followed, the attachment and transfer are not limited by the surface shape of the article to be decorated.

Further, similarly, since the image receiving layer 3 having an image is very thin, it can be easily integrated with the article to be decorated, unlike the conventional sticker, and there is no swelling of the sticking part or the transfer part.
It does not give a so-called sticking feeling.

In the above example, since the image receiving layer 3 alone is thin, these layers are insufficient in sheet feeding in the printer during image formation by thermal transfer, cushioning property or thermal efficiency during printing, and also before and after image formation. Since it is difficult to handle, the presence of the sheet-shaped substrate 1 is necessary. Further, the image receiving layer 3 provided on the sheet-shaped substrate 1 is required to be easily peelable after the image formation, and therefore, the image receiving layer 3
The sheet-shaped substrate 1 and the sheet-shaped substrate 1 should not be strongly adhered to each other, and the weak adhesive layer 2 is provided so that they can be easily peeled off.
Therefore, the term "weakly sticky" in the present invention means that the image receiving layer 3 or the sheet-shaped substrate can be easily peeled from the other side without being broken by fingers or other means.

FIG. 2 shows a preferred example of the transfer sheet 10 of the present invention, in which a release layer 4 is provided on the surface of the image receiving layer 3.

The release layer 4 is for preventing the heat transfer sheet and the image receiving layer 3 from sticking to each other when heat is transferred from a transfer sheet (not shown) to form an image on the image receiving layer 3. It is not necessary when such adhesion does not occur or when such a release layer is provided on the surface of the thermal transfer sheet.

The example shown in FIG. 3 is the same as the example shown in FIG. 2 except that a protective film layer 5 is further provided between the image receiving layer 3 and the weak adhesive layer 2. The protective film layer 5 preferably forms an image of a reversal image, and the image receiving layer 3 separated from the sheet-like substrate 1 together with the protective film layer 5 is a surface (image forming surface) of the image receiving layer 3.
Is to prevent deterioration of the image of the image receiving layer 3 when it is attached to the article to be decorated, and is excellent in various physical properties such as abrasion resistance, light resistance, weather resistance and chemical resistance. It is formed from the material. By providing such a protective film layer 5, it is possible to improve various toughness of the image after being attached to the article to be decorated.

In the above-mentioned third illustrated example, another release layer (not shown) is provided between the protective film layer 5 and the weak adhesive layer 2 in order to make the protective film layer 5 and the weak adhesive layer 2 peelable. It may be provided. It is not necessary when the surface of the protective film layer 5 has sufficient peelability.

Next, the decoration method of the present invention will be described. The decoration method of the present invention is mainly characterized in that the transfer sheet 10 of the present invention as described above is used.

As a basic mode, a method illustrated in FIGS. 4 to 5 will be described.

In the example shown in FIG. 4, the transfer sheet 10 shown in FIG. 1 is used. First, a conventionally known heat transfer sheet 20 containing a heat transferable dye (sublimation dye) as a recording agent is used as the transfer sheet.
10, the dye carrying layer 21 of the thermal transfer sheet 20 is the transferred sheet 10
Of the thermal transfer sheet 20 or the transfer target sheet 10, preferably from the transfer sheet 20 side, by a thermal head in accordance with an image signal to generate thermal energy (arrow). ), The desired image 6 is formed on the image receiving layer 3.

Then the image-receiving layer 3 with the image 6 thus formed
When the sheet is peeled from the sheet-shaped substrate 1 and attached to the article to be decorated, the attaching surface may be the image forming surface or the opposite surface. In the case of sticking to the article to be decorated on the image forming surface, the image 6 that is visually perceived is a reverse image, and therefore it is preferable to form a reverse image on the image receiving layer 3 in advance during image formation.

On the other hand, when the opposite side of the image forming surface is attached to the article to be decorated, the image is visually perceived as it is, and thus a normal image may be formed. Further, in this case, the sheet-shaped substrate 1 and the weak adhesive layer 2
If the space between and is made to be peelable, the weak adhesive layer 2 remains on the image receiving layer 3 side, and therefore, the weak adhesive layer 2 can be used to directly adhere to the article to be decorated. Of course, it is of course possible to use another pressure-sensitive adhesive or adhesive at the time of sticking in any case.

When the image-receiving layer 3 on which the image 6 is formed is attached to the article to be decorated without being peeled from the sheet-shaped substrate 1, the sheet-shaped substrate 1 is peeled after the attachment. In this case, the image after peeling of the sheet-shaped substrate 1 is a reverse image, and therefore it is preferable to form a reverse image on the image receiving layer 3 in advance in the same manner as above.
Further, since the peeling surface is the outermost layer, peeling is performed by the protective film layer 5
It is preferable that it occurs between the adhesive layer 2 and the weak adhesive layer 2.

Further, since the image receiving layer 3 is generally formed of a thermoplastic resin which can be dyed with a heat transferable dye, it does not require any adhesive or pressure sensitive adhesive and can be used as it is as a plastic molding, cloth, metal or other decorative object. It is also possible to heat bond the article.

The fifth illustrated example is the transferred sheet of the present invention of the third illustrated example.
In this case, the image 6 is formed in the same manner as described above, and then the image receiving layer 3 is peeled together with the protective film layer 5 at the interface between the protective film layer 5 and the weak adhesive layer 2, and then the image is formed. It is preferable that the surface to be formed is adhered to the article to be decorated, and since the protective film layer 5 becomes the outermost surface in this case, various fastnesses of the image 6 are remarkably improved. Of course, in this case as well, the image transferred to the article to be decorated becomes a reverse image, so it is preferable to form a reverse image in advance on the image receiving layer 3 during image formation.

Further, in the transfer-receiving sheet 10 of the present invention, when it is used as a transfer sheet after image formation, the image-receiving layer 3
Since it is necessary to peel off the sheet-like base material 1 from
In order to facilitate the peeling property, it is preferable to make a cut 7 in the sheet-shaped substrate 1 at a part of the edge of the transfer sheet 10. By providing such a notch 7, the image receiving layer 3 or the base material sheet 1 can be easily peeled off by bending that portion.

Although the decorative method of the present invention has been described above with reference to a basic example, the present invention can be performed by using the transfer sheet of the present invention illustrated in FIG. 2 or the transfer sheet of another embodiment of the present invention not shown. The same applies to the case of implementing the decoration method.

Next, the present invention will be described in more detail in terms of the main materials and the method for constituting the transfer sheet of the present invention as described above.

As the sheet-shaped substrate, (1) synthetic paper (polyolefin-based, polystyrene-based, etc.), (2) high-quality paper, art paper,
Coated paper, cast coated paper, wallpaper, backing paper, synthetic resin or emulsion mixed paper, synthetic rubber latex impregnated paper, synthetic resin internal paper, paperboard, cellulose fiber paper,
(3) Films or sheets of various plastics such as polyolefin, polyvinyl chloride, polyester, polystyrene, polymethacrylate, and polycarbonate, which are used in conventional transfer sheets, can be used, and the shape is not limited at all. Thickness is generally several μm
To a range of several hundreds μm.

Of these, the synthetic paper (1) is preferable because it has a microvoid layer having a low heat transfer coefficient (in other words, a high heat insulating property) on its surface. Further, a laminated body formed by any combination of the above (1) to (3) can also be used.

The material constituting the image receiving layer is for receiving a heat transferable dye that moves from the heat transfer sheet, for example, a sublimable (heat transferable) dye, and holding an image formed by the reception. For example, the following synthetic resins can be used alone or as a mixture of two or more kinds.

Polyester resin, polyacrylic ester resin, polycarbonate resin, polyvinyl acetate resin, styrene acrylate resin, vinyl toluene acrylate resin, polyurethane resin, polyamide resin, urea resin, polycaprolactone resin, polystyrene resin, polyvinyl chloride resin, polyacrylonitrile resin etc.

Among the above synthetic resins, polyester resins are particularly preferred.

In any of the above cases, the image is received for the purpose of improving the whiteness of the image receiving layer to further improve the sharpness of the transferred image, imparting writability to the surface of the transferred sheet, and preventing bleeding of the transferred image. White pigments can be added in the layers.

Further, in order to further enhance the light resistance of the transferred image, an ultraviolet absorber and / or a light stabilizer may be added to the image receiving layer.

The image receiving layer made of the above materials can be formed by any conventionally known method such as a coating method and a transfer method, and the thickness thereof is generally in the range of about 1 to 50 μm.

The transfer-receiving sheet of the present invention has a release layer formed on the image-receiving layer surface thereof in order to improve the release property from the thermal transfer sheet during image formation, or alternatively, a release agent in the image-receiving layer. Can be included. Examples of the release agent include solid waxes such as polyethylene wax, amide wax, and Teflon powder; fluorine-based and phosphoric acid ester-based surfactants; silicone oil and the like, with silicone oil being preferred.

As the pressure-sensitive adhesive forming the weak pressure-sensitive adhesive layer, any pressure-sensitive adhesive used in conventionally known pressure-sensitive adhesive tapes and seals can be used, for example, polyisoprene rubber, polyisobutyl rubber, styrene butadiene rubber, butadiene acrylonitrile rubber, etc. Rubber resin, (meth) acrylate resin, polyvinyl ether resin, polyvinyl acetate resin, vinyl chloride vinyl acetate copolymer resin, polystyrene resin, polyester resin, polyamide resin, polychlorinated olefin -Based resin, polyvinyl butyral-based resin or any other adhesive, suitable tackifier, for example, rosin, dammar, polymerized rosin, partially hydrogenated rosin,
Ester rosin, polyterpene resin, terpene modified product, petroleum resin, cyclopentadiene resin, phenol resin, styrene resin, xylene resin, coumarone-indene resin, etc. are added in appropriate amounts, and further necessary. Accordingly, a softening agent, a filler, an antiaging agent and the like can be added. All such adhesives are commercially available and can be easily used.

If necessary, an organic solvent is added to the pressure-sensitive adhesive to adjust the viscosity, and for example, a conventional coating method such as roll coating, die coating, knife coating, or gravure coating, the sheet-shaped substrate or the image-receiving layer. Alternatively, the pressure-sensitive adhesive layer is formed by coating on the surface of the protective film layer. The pressure-sensitive adhesive layer thus formed may have any thickness, but it is generally preferable that the pressure-sensitive adhesive layer has a thickness of about 1 to 50 μm.

The protective film layer is peeled from the sheet-like base material together with the image-receiving layer having an image, becomes the uppermost layer when the image-receiving layer is inverted and attached to the article to be decorated, and the abrasion resistance of the image-receiving layer having an image , Which improve light resistance, chemical resistance, etc., for example, as a material for forming the protective layer, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyester, polyamide,
Plastic films such as polycarbonate and polyacrylate can be used, and particularly preferred is transparency,
A polyester film excellent in various physical properties such as abrasion resistance, further, instead of these film-like protective layer, a solution or emulsion of the above resins, further epoxy resin, alkyd resin, phenol-modified alkyd resin,
Aminoalkyd resin, phenol resin, urea resin, melamine resin, silicone resin, thermosetting acrylic resin, thermosetting polyurethane resin, or other thermosetting resin or room temperature curable resin, UV curable resin, electron beam curable resin Alternatively, an active energy ray-curable resin such as a resin may be dissolved in an appropriate solvent to prepare a coating solution or an ink, which may be used to form a coating method. The thickness of such a protective film layer is generally about 0.5 to 20 μm.

The transfer-receiving sheet of the present invention is formed from the above materials. For example, in the case of the first and second examples, a material for forming an image receiving layer is formed on the weak adhesive layer formed on the sheet-shaped substrate. The composition for image-receiving layer formation obtained by dissolution or dispersion is applied and dried by a known coating or printing method to form an image-receiving layer, and further, if necessary, a release layer is formed. As a method, the image receiving layer may be once formed on a temporary carrier different from the sheet-shaped substrate and then transferred onto the sheet-shaped substrate provided with the weak adhesive layer. If the weak adhesive layer is previously formed on the image receiving layer, the weak adhesive layer may not be formed on the sheet-shaped substrate.

In the case of the example shown in FIG. 3, the composition for forming an image receiving layer as described above is similarly applied onto various films to be the protective film layer and dried to form a release layer, if necessary. Then, this is laminated on a sheet-shaped substrate having a weak adhesive layer formed thereon by using the weak adhesive layer.
It becomes the transferred sheet illustrated.

The above method is one example, and the transfer sheet of the present invention can be obtained by any other method.

Further, the transfer-receiving sheet as described above may be provided with other releasing layer, intermediate layer and other layers as required.

The above is the constitution of the transfer sheet of the present invention, but a preferable method for forming a desired image on such a transfer sheet is to form a layer having a heat transferable dye (sublimable dye) on a sheet-like substrate. This is a method of using the provided thermal transfer sheet. Both the thermal transfer sheet itself and the thermal transfer method itself used in this method are known, and all of these known thermal transfer sheets and thermal transfer methods are useful in the present invention. Further, by such a thermal transfer method, both a mono-color image and a full-color image can be easily formed.

For example, a conventionally known thermal transfer sheet is overlaid on the thermal transfer sheet of the present invention, and any conventionally known thermal transfer device, for example, a thermal printer (e.g., Toshiba, thermal printer TN-5400) is used by a device such as 5 100m
A desired image can be formed in the image-receiving layer of the transfer sheet of the present invention by applying thermal energy of J / mm ² .

The peeling or transfer of the image-receiving layer on which an image is formed as described above is very easy because the weak adhesive layer is formed between the image-receiving layer and the sheet-shaped substrate, and a thin film having a desired image is formed. It can be peeled off. When the film having the peeled image has the above-described weak adhesive layer on the side opposite to the recording surface, the film can be directly attached to various articles to be decorated. As a matter of course, the attachment may be performed on the entire surface of the article to be decorated or a part thereof. If the image-receiving layer film does not have a weak adhesive layer in advance, the peeled image can be heat-sealed as it is according to the physical properties or material of the article to be decorated. It is also possible to apply a suitable adhesive to the image-receiving layer film or the article to be decorated and then attach the same.

Further, the film having such an image can be reversed after peeling, that is, the image forming surface is opposed to the article to be decorated, and the film can be attached to any article to be decorated in the same manner as described above.
In this case, before the receiving layer is peeled off in advance, the transfer sheet having an image is placed on the article to be decorated with the image surface thereof facing,
More preferable is a method of sticking with an adhesive if necessary, and then peeling the sheet-shaped substrate to leave an image receiving layer having an image on the article surface, that is, a transfer method. The same applies to the case where the transfer sheet of the present invention has a protective film layer, and it is possible to impart an image having various fastnesses to a decorated article.

In the case of reversing the image and attaching or transferring the image to the article to be decorated as described above, it is preferable that the image to be formed is previously formed as a reverse image having a mirror surface relationship.

As described above, the decoration method of the present invention may be any conventionally known method, except that a specific transfer sheet is used, and the image forming method and the method of attaching or transferring to the article to be decorated, The material to be decorated, which is the object of the decoration method of the present invention, its shape, etc. are not particularly limited, and for example, packages such as cartons, containers, bags, cassette cases, cassette halves, floppy cases, wrapping paper, stock certificates, checks. , Bills, securities, certificates, passbooks, tickets, train tickets, stamps, stamps, appreciation tickets, etc .; cash cards, credit cards, members' cards, greeting cards, postcards, business cards, IC cards, etc. Other forms, envelopes, tags, Shiori, calendars, posters, brochures, passports, POP supplies,
Coasters, displays, name plates, keyboards, cosmetics, accessories (clocks, lighters), stationery, building materials, radios, TVs, speakers, calculators, car instrument panels, emblems, keys, clothing, footwear, devices,
Any material or shape such as OA equipment may be used.

(Functions / Effects) According to the transfer sheet and the decoration method of the present invention as described above, a surface such as a three-dimensional molded product, a curved surface or a complicated uneven shape, which has heretofore been impossible or difficult to form and impart an image, It is possible to freely give an image formed by a heat transferable dye, regardless of the materials having the above, and the materials of these articles.

Moreover, according to the present invention, unlike the conventional so-called picture sticker, since the image-receiving layer film having an image according to the present invention is very thin, even if it is attached to an article to be decorated, they are sufficiently thin. It is integrated and does not give a feeling of sticking, and has excellent aesthetics, function and durability.

Next, the present invention will be described more specifically with reference to examples.
In the text, “part” or “%” is based on weight unless otherwise specified.

Example 1 On the surface of a polyester film (thickness 6 μm) serving as a protective film layer, an ink for forming an image receiving layer having the following composition was applied and dried to a weight of 7 g / m ² after drying.

Were overlapped with each other, and thermal energy was applied by a thermal head connected to an electric signal of a cyan component obtained by color-separating a face photograph to obtain a cyan image.
Then, thermal transfer was performed in the same manner using a thermal transfer sheet using a magenta dye and a thermal transfer sheet using a yellow dye, thereby forming an image consisting of a full-color photograph and other characters and figures. The image was formed as a reverse image.

The image receiving layer side of the sheet on which the image is formed has a thickness of 100 μm.
On a card base made of white opaque hard vinyl chloride resin sheet and pressure-bonded with a heat roller at 200 ° C. After pressure-bonding, the sheet-shaped substrate is peeled off together with the weak adhesive layer at the interface between the protective film layer and the weak adhesive layer. Then, a card to which the image receiving layer having a display image was transferred was obtained.

The surface of this card was smooth as a whole, and there was little swelling in the image portion. Furthermore, the image of this card is 40 ℃

The grade was 4 to 5, showing good performance. It also showed good resistance to scratches on the surface.

Example 2 In the same manner as in Example 1 below, except that an image receiving layer was similarly formed on the surface of the sheet-shaped substrate on which the weakly adhesive layer was formed in Example 1 without a protective film layer interposed therebetween to form a normal image. An image was formed. Then, the image-receiving layer having the image formed thereon was peeled off, the polyester-based adhesive was applied to the peeled surface of the peeled film, and this was stuck to the curved surface of the telephone. It closely follows the curved surface of the phone, integrates with the curved surface, does not give the sticking feeling like a sticker, and gives the feeling of directly printing an image.

Example 3 An image was formed in the same manner as in Example 2 except that a reverse image was formed on the transfer sheet in Example 2, and a glass cup made of an adhesive agent was applied to the image side without peeling off the image layer. When the sheet-like base material was peeled off together with the weak adhesive layer, it gave almost no sticking feeling and gave the appearance as if printed directly.
