Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking sheet capable of producing a multicolor mark by one cutting and one thermocompression bonding and a method for producing the multicolor mark.

[0002]

2. Description of the Related Art In a conventional transfer sheet, the support is a release paper, or
It was a method of transferring using a film with a weak tackiness adhesive called an application film (JP-A-2-196693, JP-A-3-45672, JP-A-3-244682, and JP-A-6-55734). Etc.). However, these methods have a drawback that operations such as alignment become very complicated, and many transfer defects occur.

In order to remedy such drawbacks, a marking sheet in which a coloring layer and a thermal adhesive layer are sequentially laminated on a plastic film support has been proposed and has been widely used in recent years. This marking sheet can be attached by a simple method, and since a transparent or semi-transparent plastic film is used as a support, the work such as alignment becomes very easy. Furthermore, when a stretchable material such as urethane is used, the stretch of the fabric made of fibers is well followed, so that it has come to be used as a number for sportswear.

However, in the case of producing a multicolored mark having an edge, after cutting the marking sheet of the color of the edge portion into a desired figure, it is thermocompression-bonded to the adherend, and then different from the edge portion. It was necessary to repeat the operation of cutting the color marking sheet into a size different from that of the edge portion, superposing it on the edge portion, and thermocompression-bonding it again for each color. Further, there is a problem that air bubbles enter into the overlapped portions during such work, or misalignment occurs so that the contour portion is unsharply formed, which significantly reduces the commercial value.

There are also cases where a multicolor mark is produced by a method such as silk printing, but since a pattern or the like is printed in advance on the conventional transfer sheet, the user can select from the given print pattern or the like. However, there is a drawback that the transfer sheet can only be used to select a desired one, and the application or versatility of the transfer sheet is narrow. In addition, in the case of a transfer sheet such as a multi-color silk screen printing, in order to produce an original mark, it is necessary to print a large amount from the viewpoint of cost and the like. There was a problem that it was not done at all, and it was practically impossible to make an original mark only for oneself.

In order to improve the above-mentioned problems, the inventors of the present invention have made various studies on the sticking method, materials used, etc., and as a result, at least two colored layers and a heat-bondable heat-bonding layer on the plastic film support. By using a marking sheet in which an adhesive layer and a separator are sequentially laminated,
The present invention has been completed by finding that a multicolor mark having a desired color with no misalignment can be obtained by a simple operation of one cutting and one thermocompression bonding.

SUMMARY OF THE INVENTION The present invention provides a method for manufacturing a semiconductor device comprising the steps of:
A marking sheet in which at least two colored layers and a temporary adhesive heat-adhesive layer are sequentially laminated from the side of the support, and a separator is laminated on the temporary adhesive heat-adhesive layer is used. Thus, a multicolor mark having a desired color can be obtained by a simple operation.

In the marking sheet 7 of the present invention, as shown in FIG. 1, a coating 4 composed of a first colored layer 21, a second colored layer 22, and a heat-adhesive layer 3 which can be temporarily adhered is sequentially formed on a support 1. It has a structure in which a separator 5 is laminated, and further, a separator 5 is laminated on the heat-bonding layer 3 which can be temporarily adhered. In addition, although the colored layer is composed of two layers in FIG. 1, any number of colors can be expressed by stacking the colored layers according to the number of colors to be used. Even when it has three or more colored layers, the structure and the manufacturing method are substantially the same as those of the two-layered structure, and therefore the following description will be made by taking the case of two colored layers as an example.

The method for producing a multicolor mark in the present invention is as follows.
The feature is that a multicolor mark of a desired color can be easily produced by one cutting and one thermocompression bonding. Hereinafter, description will be given with reference to the drawings.

The method for producing a multicolor mark of the present invention uses the above-mentioned marking sheet 7 of the present invention (FIG. 4) to sequentially perform the following steps (1) to (4) (first step). Method of making).

(1) The separator 5 and the film 4 are cut from the marking sheet 7 from the separator 5 side without cutting the support 1 (FIG. 5). (2) At least the unnecessary portion of the thermal adhesive layer 3 that can be temporarily bonded to the separator 5 is peeled off (FIG. 6), and the separator 5 of the desired pattern portion is peeled off from the temporarily adhesive thermal adhesive layer 3 (FIG. 7). ). (3) The heat-adhesive layer 3 capable of temporary adhesion and the adherend 8 are superposed so as to face each other and temporarily adhered to the adherend 8 (FIG. 9),
The support 1 and, if necessary, an unnecessary portion of the colored layer are peeled off (FIG. 11). (4) At least one of the colored layers of the portion whose color is to be changed
The layer 21 is peeled off entirely or partially (FIG. 12) and thermocompression bonded (FIG. 13).

As another method of producing a multicolor mark, the following steps (1) to (4) are sequentially carried out using the marking sheet 7 (FIG. 4) of the present invention described above ( Second manufacturing method).

(1) The separator 5 and the film 4 are cut from the marking sheet 7 from the separator 5 side without cutting the support 1 (FIG. 5). (2) The separator 5 having only the desired pattern portion is peeled and removed from the heat-bonding layer 3 capable of temporary bonding (FIG. 8). (3) The heat-adhesive layer 3 which can be temporarily adhered and the adherend 8 are superposed so as to face each other and temporarily adhered to the adherend 8 (see FIG. 1).
0), the unnecessary portion of the separator 5 and the film 4 are peeled off together with the support 1 (FIG. 11). (4) At least one of the colored layers of the portion whose color is to be changed
The layer 21 is peeled off entirely or partially (FIG. 12) and thermocompression bonded (FIG. 13).

In the first method, at least an unnecessary portion of the thermal adhesive layer 3 which can be temporarily adhered to the separator 5 is peeled and removed,
The film 4 in the unnecessary portion is prevented from being transferred to the adherend 8. On the other hand, in the second method, the film 5 of the unnecessary portion is removed by not peeling the separator 5 of the unnecessary portion.
Prevents the transfer to the adherend. That is, in the second method, only the portion where the separator 5 is peeled off after cutting is transferred to the adherend 8 and the portion where the separator 5 is not peeled off and the separator 5 and the film 4 can be peeled off together with the support 1. It was done like this. In addition, in the first method, the unnecessary film 4
If the whole is peeled and removed, the contour of the pattern to be attached can be confirmed at the stage after the temporary attachment and before the attachment. Further, after the temporary adhesion, the support 1 and, if necessary, the coloring layer of the unnecessary portion are peeled and removed, and at least one layer of the coloring layer of the portion whose color is to be changed is peeled and removed while the mark is viewed in a normal image to remove the multicolor The mark is obtained.

A desired multicolor mark can be easily produced by the first and second production methods as described above. However, when the colored layer is softened and melted during thermocompression bonding, the heat resistance and the colored layer are reduced. On the other hand, it is advisable to place paper, film or the like having releasability on the colored layer and then perform thermocompression bonding.

Next, the marking sheet of the present invention will be described in detail.

As the support 1, paper, synthetic paper, resin-impregnated paper or the like can be used, but a substantially transparent or translucent plastic film such as polypropylene, polyvinyl chloride, polystyrene, polycarbonate, polyethylene terephthalate, polyethylene na. It is desirable to use phthalate or the like. If the support 1 is transparent or semi-transparent, it is easy to perform alignment when temporarily adhering to an adherend after cutting and peeling off the unnecessary portion of the film 4. Therefore, the transparency of the support 1 should be such that the position of the adherend can be confirmed.

A glossy image can be obtained if the surface of the support 1 on the laminate side is smooth, and a matte image can be obtained by using a roughened support.

Further, when cutting with a cutting plotter or the like, it is possible to cut out accurately without slippage, and to prevent blocking between the non-laminated side of the support 1 and each layer during the manufacturing process, non-laminated The surface of the side support may be matted by sandblasting or the like.

The thickness of the support 1 is not particularly limited, but it is preferable that it is not too thin due to workability when cutting or peeling off the unnecessary film 4 and the like. It is better not to be too thick from the aspect of. Therefore, it is generally 25 depending on the working conditions and materials.
The one having a thickness of about 250 μm is used.

Further, after cutting, the separator 5 is peeled and removed from the heat-bonding layer 3 which can be temporarily bonded, the unnecessary portion of the film 4 is peeled and removed from the support 1, and temporarily adhered to the adherend to be colored. Since the support 1 is peeled off from the marking sheet 7 in order to change the above, it is necessary to have an appropriate adhesive force with the first colored layer 21. Therefore, depending on the support used, it is preferable to subject the support to an appropriate release treatment or undercoating treatment. In particular, as the undercoating treatment, if a natural or synthetic rubber-based material having low tackiness is used, the coating 4 does not fall off after it is cut, and if the coating 4 is accidentally peeled, it can be re-bonded. When performing these undercoating treatments, it is preferable that the undercoating layer remains on the support 1 side after peeling. However, an undercoat layer without tack can be left on the colored layer side in order to prevent tacking or blocking of the surface of the colored layer after sticking.

For the first colored layer 21 and the second colored layer 22, a film-forming resin or resin solution in which a dye, a pigment, a metal powder or the like is dispersed or dissolved is used. As the resin, vinyl chloride resin, vinyl acetate resin, vinylidene chloride resin, cellulose resin, polyester resin, urethane resin, polyamide resin, polystyrene resin, acrylic resin, olefin resin, nitrile rubber, etc. One kind or two or more kinds of resins can be used. In addition, when used by being attached to a cloth, a resin having flexibility to follow the elongation of the cloth and having water resistance so as not to be peeled off by washing or the like is preferably used. Among the resins, Urethane resins are particularly preferable.

It is preferable that the first colored layer 21 and the second colored layer 22 have a performance such as a slight adhesiveness such that the layers are not peeled off when they are cut between the adjacent layers. The adhesiveness is such that the layers between the colored layers and the layer between the heat-adhesive layer 3 that can be temporarily adhered and the second colored layer 22 that is in contact with the layers do not peel off or fall off when cut, and
Work is easily performed when peeling between the layers of the colored layers where the color is desired to be changed or between the non-sticking portion (unnecessary portion) of the temporarily adhesive heat-adhesive layer 3 and the second colored layer 22 in contact therewith. It is preferably as high as possible. If a layer that does not have a slight adhesiveness between the colored layers is used, for example, as shown in FIG. 2, the adhesiveness between the first colored layer 21 and the second colored layer 22 is slightly reduced. You may provide the adhesive layer 6 which has. Further, other than the above, a method may be used in which the layers between the colored layers are not separated by an operation such as cutting.

Further, it is preferable that the layers between the colored layers and the layer between the heat-adhesive layer 3 which can be temporarily adhered and the second colored layer 22 in contact with the layer are firmly adhered after thermocompression bonding. As a method of firmly adhering after thermocompression bonding, for example, the colored layer (the first colored layer 21 or the second colored layer 22) is made of a material that is slightly melted by the heat at the time of attachment, and the colored layers are mutually bonded by thermocompression bonding. There may be mentioned a method of firmly melting and adhering the heat-adhesive layer 3 capable of temporary adhesion and the second colored layer 22 in contact therewith.

The thickness of the first colored layer 21 and the second colored layer 22 is such that the coating film strength is not lost, and after the application, the color of the underlying colored layer and the pattern of the adherend. The thickness is preferably such that the above can be concealed, and from the viewpoint of cutting property, peeling property, productivity, etc., 5 to 150 μm is preferable.

The first coloring layer 21 and the second coloring layer 22 are usually mixed with dyes or pigments for coloring. However, if a metal thin film layer or the like is provided above or below the coloring layer, the dye is added to the coloring layer. It may be colorless without mixing a pigment or a pigment, and the colored layer may be replaced with a metal thin film layer or the like.

Further, a transparent resin is used for the first colored layer 21 in contact with the support 1, and the mark is given an originality by patterning the first colored layer 21 or coloring it with a dye. Is also possible. For example, the first colored layer 21
Are colored with a fluorescent dye, and the second colored layer 22 is colored with a white pigment, whereby a brighter fluorescent color mark can be produced.

Further, when a cloth made of fibers whose dyes are easily sublimated by heat during thermocompression bonding is used as an adherend, a barrier is applied so that the dye does not stain the colored layer and the color tone of the mark background does not change. Layers can also be provided (Japanese Patent Laid-Open No. 7-83242)
No. 26479). This barrier layer may be provided anywhere, but since the unnecessary coloring layer is peeled off and removed, it is particularly effective if it is provided between the heat-adhesive layer 3 that can be temporarily adhered and the second coloring layer 22 that is in contact therewith. is there.

The adhesive layer 6 used in the above may be any substance having a slight adhesive property at room temperature, and it is necessary for the adhesive layer 6 to firmly adhere the colored layers to each other after thermocompression bonding. Further, those having water resistance are preferable so as not to be peeled off by rain or washing. For example, various types such as rubber-based resins, acrylic-based resins, urethane-based resins, ethylene / vinyl acetate-based resins, styrene / isoprene-based resins, and other organic solvents or aqueous solutions, and water dispersions can be used.

The adhesive layer 6 is preferably one that remains on the side of the colored layer to be peeled off and is removed together with the colored layer when peeling between the colored layers at the portions whose color is desired to be changed. It is also possible to put a curing agent in a microcapsule, mix it with a resin, and apply pressure to break the microcapsule to cure it. Furthermore, beads made of acrylic or the like may be added to the resin, and the adhesive amount may be adjusted by changing the addition amount of the beads.

For the heat-bonding layer 3 that can be temporarily bonded, it is preferable to select a material having good adhesion depending on the type of the adherend. At room temperature
Those having strong tackiness are preferably used. For example, vinyl-based copolymer, olefin-based resin, polyamide-based resin,
One or more urethane resins, polyester resins, epoxy resins and phenol resins are used. Further, when used by being attached to a cloth, a resin having flexibility to follow the elongation of the cloth and having water resistance so as not to be peeled off during washing is preferably used. Among them, urethane resin is particularly preferable.

The heat-adhesive layer 3 which can be temporarily adhered may contain a colorant, if necessary.

When the heat-bonding layer 31 that cannot be temporarily bonded is used, as shown in FIG.
May be laminated to form the heat-bonding layer 3 that can be temporarily bonded.

As the film thickness of the heat-bonding layer 3 which can be temporarily bonded,
Although it depends on the adherend, it is possible to adhere the adherend if it is a textile product such as clothing having a thickness of 10 μm or more. In order to improve the adhesive strength, it is preferable that the film thickness is thick, but if it is too thick, it may cause inconvenience in cutting property, productivity, etc., and therefore, it is preferably 200 μm or less.

The temporary adhesive layer 32 may be any substance having a strong adhesive property at room temperature, and when the temporary adhesive layer is temporarily adhered to an object to be adhered and then peeled off when it is desired to change a place to be adhered, the temporary adhesive layer is adhered. It is preferable not to transfer to a kimono. As those having these properties, for example, a rubber resin, an acrylic resin,
Various types such as urethane type resins, ethylene / vinyl acetate type resins, styrene / isoprene type resins, and other organic solvents or aqueous solutions, water dispersions and the like can be mentioned.

A separator 5 is laminated in order to protect the surface of the heat-bonding layer 3 that can be temporarily bonded or the surface of the temporary bonding layer 32. As the separator 5, a polyethylene resin is generally laminated on the surface of a paper base material such as high-quality paper, kraft paper, glassine paper, etc., and the polyethylene resin surface is coated with a silicone resin, or a plastic film which has been previously treated. Etc. are used.

Further, it is preferable to use a material suitable for the temporary adhesive layer so that the separator can be cut without floating during cutting.

Next, a method for producing a multicolor mark of the present invention (first method) in which the following steps (1) to (4) are sequentially performed
Will be used to explain the marking sheet of the present invention in more detail. Since the performance required for the marking sheet itself is the same as that of the first method when the second method is used, the first method will be described here as an example.

(1) The separator 5 and the film 4 are cut from the marking sheet 7 from the separator 5 side without cutting the support 1 (FIG. 5). (2) The unnecessary portion of the separator 5 and the film 4 are peeled off from the support 1 (FIG. 6), and the desired pattern portion of the separator 5 is peeled off from the heat-bonding layer 3 capable of temporary adhesion (FIG. 7). (3) The heat-adhesive layer 3 capable of temporary adhesion and the adherend 8 are superposed so as to face each other and temporarily adhered to the adherend 8 (FIG. 9),
The support 1 is peeled off (FIG. 11). (4) The first colored layer 2 of the colored layers of the portion whose color is to be changed
1 is peeled off all or part of the surface (FIG. 12) and thermocompression bonded (FIG. 13).

In this case, it is preferable that the unnecessary portion of the separator 5 and the film 4 can be easily peeled and removed after cutting, and that the colored layers of the portion whose color is desired to be changed can be peeled off. That is, before thermocompression bonding, the layer between the support 1 and the first colored layer 21 in contact therewith, the layer between the colored layers, and the layer between the separator 5 and the heat-adhesive layer 3 that can be temporarily adhered can be peeled off. It is characterized in that it becomes difficult to separate the colored layers from each other by pressure bonding.

Before thermocompression bonding, the support 1 and the first
If it is difficult to peel off the layer from the colored layer 21, not only the unnecessary portion of the film 4 cannot be peeled off, but also the support 1 cannot be peeled off after the temporary adhesion, and a desired pattern cannot be obtained. Further, if the film 4 of the unnecessary portion can be peeled off, the contour of the pattern to be attached can be confirmed at the stage before the attachment. Furthermore, a multicolor mark cannot be obtained unless the colored layers can be separated from each other. At this time, it may be difficult to peel off the interlayer between the heat-bonding layer 3 that can be temporarily bonded and the second colored layer 22 that is in contact with the heat-bonding layer 3. Also, after thermocompression bonding,
The reason why peeling between the colored layers is difficult is that peeling between the colored layers causes problems such as peeling during use, resulting in a marked decrease in commercial value.

Further, in producing a multicolor mark,
The relationship of the adhesive force between the layers will be described in detail. Note that, for convenience of description, the adhesive force between the layers is displayed as follows.

: Support 1 and first colored layer 2 in contact therewith
Adhesion between layers with 1. : Adhesive force between the colored layers. : Adhesion between the heat-bonding layer 3 that can be temporarily bonded and the second colored layer 22 that is in contact with the heat-bonding layer 3. : Adhesive force between the layers of the heat-bondable layer 3 and the separator 5 that can be temporarily bonded. : Adhesive force between layers of the heat-adhesive layer 3 that can be temporarily adhered and the adherend 8.

When the unnecessary portion of the separator 5 and the film 4 are peeled from the support 1 after cutting, the relation of the adhesive force between the respective layers is ≤≤≤ (,
) Is preferable. When it is <, when peeling the separator 5 for temporary adhesion to the adherend 8 (FIGS. 6 to 7), peeling easily occurs between the support 1 and the first colored layer 21 and workability is improved. Deteriorate. When the support 1 is peeled off after the temporary adhesion (FIGS. 9 to 11), if <, peeling is likely to occur between the colored layers, resulting in poor workability.
Further, when peeling between the layers of the colored layers where the color is desired to be changed (FIG. 11 to FIG. 12), when <, the thermal adhesive layer 3 which can be temporarily adhered and the second colored layer 22 which is in contact with the thermal adhesive layer 3 are provided between the layers. Peeling is easy, and when <, peeling easily occurs between the adherend 8 and the heat-bonding layer 3 that can be temporarily adhered, and it becomes difficult to peel between the colored layers, resulting in very poor workability.

After thermocompression bonding (FIG. 13), it is preferable that all layers become difficult to peel. This is because if the layers are easily peeled off after thermocompression bonding, delamination is likely to occur at the time of using the adherend after sticking and it becomes impossible to endure use.

The above explanation applies to the separator 5 of the unnecessary portion.
And the case where the entire film 4 is peeled off, only the heat-bonding layer 3 that can be temporarily bonded to the unnecessary separator 5 (FIG. 14), or the unnecessary separator 5, the heat-bondable layer 3 that can be temporarily bonded, and At least one colored layer 22
It is also possible to produce a multicolor mark by peeling and removing (FIG. 15). In this case, it is preferable that the adhesive force between the layers be appropriately adjusted so that the work can be performed easily.

These layers can be laminated by dispersing or dissolving them in a solvent or the like, or by heat-melting them and successively coating and laminating on the support 1. In addition, a colored layer of a desired color (the first colored layer 21 and the second colored layer 22, or the first colored layer 21) is laminated on the support 1 by a known method, while temporary adhesion is performed on the separator 5. Possible heat-adhesive layer 3 or a desired second colored layer 22 laminated on the heat-adhesive layer 3 which can be temporarily adhered by a known method to obtain a colored layer on the support 1 (second colored layer 22 or First colored layer 2
A method in which 1) and the heat-bondable layer 3 that can be temporarily bonded or the second colored layer 22 on the heat-bondable layer 3 that can be temporarily bonded are laminated and laminated so as to face each other is also possible. It is also possible to provide each layer on a separate support one by one and laminate them by a laminating method.

As a method for applying such a layer, known methods such as a bar coating method, a roll coater method and a curtain flow method, an extrusion method, a hot melt roll coater method and a die coating method can be used. .

[0049]

According to the method for producing a marking sheet and a multicolor mark of the present invention, a desired multicolor mark can be obtained by one cutting and one thermocompression bonding. The step in the portion where the colored layers overlap is almost eliminated by thermocompression bonding to the adherend, and the appearance is very good in use. Further, since the layers are not laminated (thermo-compression bonding twice or more), bubbles do not enter between the layers of the mark.
