Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking sheet capable of producing a double mark by one cutting and one thermocompression bonding, and a method for producing the double 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 adhesive called an application film. 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 heat-adhesive layer are sequentially laminated on a plastic film support has been proposed and has been widely used in recent years (JP-A-2- 196693, JP-A-3-45672, JP-A-3-244682, and JP-A-6-55734). 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 highly stretchable material such as urethane resin is used, it can follow the stretch of the fabric made of fibers well, so that it has come to be used for sportswear bib etc.

However, in the case of producing a double mark having an edge, after cutting the marking sheet of the color of the edge portion into a desired pattern, 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.

In some cases, a double 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 print pattern or the like given. However, there is no choice but to choose what you want,
There is a drawback in that the transfer sheet has a narrow use or versatility. In addition, in the case of a transfer sheet such as a multicolor silk screen printing, in order to produce an original mark, it is necessary to print a large amount from the viewpoint of cost.
The production of only one sheet has a problem that it is not actually done at all because the cost rises, and it is practically impossible to produce the original mark only for oneself.

In order to solve the above-mentioned problems, the inventors of the present invention have conducted various studies on the sticking method, the materials used, etc., and as a result, a colored layer and a colored heat-adhesive film capable of temporary adhesion on the plastic film support. By using a marking sheet in which layers are sequentially laminated, it has been found that a double mark without deviation in a desired color can be obtained by a simple operation of one cutting and one thermocompression bonding. Was completed.

SUMMARY OF THE INVENTION The present invention provides a method for manufacturing a semiconductor device comprising the steps of:
In order from the support side, by using a marking sheet provided with a coating formed by sequentially stacking a colored layer and a colored heat-adhesive layer capable of temporary adhesion, in a desired color, and,
A double mark can be obtained by a simple operation.

As shown in FIG. 1, the marking sheet 6 of the present invention has a structure in which a coating 4 composed of a colored layer 2 and a colored heat-adhesive layer 3 capable of temporary adhesion is sequentially laminated on a support 1. Have.

The double mark manufacturing method of the present invention is one in which the following steps (1) to (4) are sequentially performed using the marking sheet 6 (FIG. 4) of the present invention described above.

(1) The coating 4 is cut from the side of the colored heat-adhesive layer 3 of the marking sheet 6 which can be temporarily adhered, without cutting the support 1 (FIG. 5). (2) Peel off at least the temporary heat-bondable colored heat-bonding layer 3 of the unnecessary portion (FIG. 6), and give tackiness to the temporarily heat-bondable colored heat-bonding layer 3 (desired pattern part). . (3) Colored heat-adhesive layer 3 capable of temporary adhesion and adherend 7
They are superposed so that and face each other, and temporarily adhered to the adherend (FIG. 7), and the support 1 and, if necessary, an unnecessary portion of the colored layer are peeled off (FIG. 8). (4) The colored layer 2 in the portion whose color is to be changed is peeled off (FIG. 9) and thermocompression bonded (FIG. 10).

In addition to this, in the step (2), there is also a method in which the unnecessary portion is not peeled off, the unnecessary portion is masked, and the adhesiveness is given only to the desired pattern portion.

According to this method, at least the unnecessary portion of the colored heat-adhesive layer 3 capable of temporary adhesion is peeled off to prevent the coating 4 of the unnecessary portion from being transferred to the adherend 7. Further, when the entire unnecessary film 4 is peeled off and removed, the contour of the pattern to be attached can be confirmed before the temporary adhesion. Further, after temporarily adhering, the support and, if necessary, the coloring layer 2 in unnecessary portions are peeled and removed, and the coloring layer 2 in a portion whose color is to be changed is peeled and removed while seeing the mark in a normal image, and thermocompression bonding is performed to double the layer. The mark is obtained.

A desired double mark can be easily produced by such a method, but in the case where the colored layer 2 and the colored thermal adhesive layer 3 which can be temporarily adhered are softened and melted during thermocompression bonding. It is advisable to place a paper, a film or the like, which is heat resistant and has releasability on the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered, 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 the adherend 7 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 7 can be confirmed.

A glossy image can be obtained if the surface of the support 1 on the laminated 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 better not to be too thin in view of workability in cutting and peeling the film 4 and the like of unnecessary portions.
From the viewpoint of cost, it is better not to be too thick. For this reason, it is generally 25-250μ, although it depends on the working conditions and materials.
m is used.

When peeling the film 4 from the support 1, proper adhesion between the support 1 and the colored layer 2 is required. Therefore, depending on the support used, it is preferable to subject the support to an appropriate release treatment or subbing treatment.
In particular, as the undercoating treatment, if a natural or synthetic rubber-based material having low tackiness is used, the coating film does not fall off after cutting, and if the coating film 4 is accidentally peeled off, 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, in order to prevent tacking or blocking of the surface of the colored layer 2 and the surface of the colored heat-adhesive layer 3 that can be temporarily adhered after the attachment, the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered are provided on the side of the colored layer 2 You can also leave the undercoat layer without tack.

For the colored layer 2, 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.

Further, it is preferable that the colored layer 2 has a performance such as a slight adhesiveness such that it is not peeled off between the adjacent layers when it is cut. As the tackiness, the layer between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered does not peel off or fall off when cut, and the part whose color is desired to be changed or the non-adhesive part (unnecessary part) When peeling between the colored layer 2 of 4) and the colored heat-adhesive layer 3 that can be temporarily adhered, it is preferable that the work can be easily performed. If a layer that does not have a slight adhesive property is used between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily bonded, for example, as shown in FIG. An adhesive layer 5 having a slight adhesiveness may be provided between the adhesively colored heat-adhesive layer 3 and the layer. In addition to the above, a method may be used in which the layers are not peeled off by an operation such as cutting.

Furthermore, it is preferable that the layers between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered are firmly adhered after thermocompression bonding. As a method for firmly adhering after thermocompression bonding, for example, a colored thermoadhesive layer that is made of a material that slightly melts the coloring layer 2 by the heat at the time of adhesion and can be temporarily adhered to the coloring layer 2 by thermocompression bonding. There may be mentioned a method of firmly melting and adhering the layer with No. 3.

The thickness of the colored layer 2 is such that the coating film strength is not lost, and after the application, the color of the colored heat-adhesive layer that can be temporarily adhered below and the adherend 7 The thickness is preferably such that a pattern or the like can be hidden, and from the viewpoint of cutting property, peeling property, productivity, etc., 5 to 150 μm is preferable.

The coloring layer 2 is usually mixed with a dye or a pigment for coloring. However, if a metal thin film layer or the like is provided above or below the coloring layer, the coloring layer is not mixed with the dye or pigment and is colorless. Alternatively, the colored layer may be replaced with a metal thin film layer or the like.

It is also possible to impart originality to the mark by using a transparent resin for the colored layer 2 and providing the colored layer 2 with a pattern or coloring with a dye.
For example, if the colored layer 2 is colored with a fluorescent dye and the colored heat-adhesive layer 3 that can be temporarily adhered is colored with a white pigment, a brighter fluorescent color mark can be produced.

Further, when a cloth made of fibers in which the dye is easily sublimated by heat during thermocompression bonding is used as the adherend 7, the dye is dyed on the coloring layer 2 and the color tone of the mark base does not change. A barrier layer may be provided as described above (Japanese Patent Laid-Open No. 7-26479). This barrier layer is effectively provided between the colored layer 2 and the temporary heat-bondable colored heat-bonding layer 3 if the color of the temporary heat-bondable heat-bonding layer is dark.

The adhesive layer 5 used in the above may be a substance having a slight adhesive property at room temperature, and the adhesive layer 5 is a colored thermal adhesive layer 3 which can be temporarily adhered to the colored layer 2 after thermocompression bonding. It is necessary to firmly bond the. Further, those having water resistance are preferable so as not to be peeled off by rain or washing. For example, rubber resin, 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.

The adhesive layer 5 remains on the side of the colored layer 2 to be peeled off and removed together when peeling between the colored layer 2 in the portion whose color is desired to be changed and the colored heat-adhesive layer 3 which can be temporarily adhered. Those that are removed are preferred. 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. Alternatively, the adhesive force may be adjusted by adding beads made of acrylic or the like to the resin and changing the addition amount of the beads.

For the colored heat-adhesive layer 3 that can be temporarily adhered, a material having good adhesion may be selected depending on the type of the adherend 7. Normally, it does not have tackiness, but it may be any substance that exhibits strong tackiness due to external factors such as moisture and heat. Also, after temporarily adhering to the adherend 7, it is desired to change the place of sticking. At the time of peeling, it is preferable not to transfer to the adherend 7. For example, polyvinyl alcohol resin, polyvinyl ether resin, cellulose resin, polyester resin, urethane resin, polyamide resin, EVA (ethylene-vinyl acetate copolymer) resin, polyolefin resin, vinyl copolymer, One type or two or more types of epoxy resin, phenolic resin and the like are used. Also,
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 the above resins, Urethane resins are particularly preferable.

When the tackiness is expressed by heat, the layer between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered is colored so that the layer can be temporarily adhered so that it does not melt due to heat and peeling becomes difficult. The heat-adhesive layer 3 is preferably one that exhibits tackiness at a melting point or softening point of the colored layer 2 or at a temperature lower than the temperature at the time of thermocompression bonding, and one that does not exhibit tackiness even when the temperature is high is used. Preferably. For example, when the temperature at the time of thermocompression bonding is around 160 ° C, it is preferable that the adhesiveness is exhibited at a temperature of about 40 ° C to 140 ° C.

When a material that cannot be temporarily bonded is selected as the colored heat-bonding layer, a temporary bonding layer 32 is laminated on the colored heat-bonding layer 31 as shown in FIG. The colored heat-bonding layer 3 may be used.

The thickness of the colored heat-adhesive layer 3 that can be temporarily adhered varies depending on the adherend, but if the adherend is a textile product such as clothing, it can be adhered if it is 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 used in the above is not normally tacky, but may be any substance that exhibits strong tackiness due to external factors such as moisture and heat.
It is preferable that the temporary adhesive layer 32 does not transfer to the object 7 to be adhered when the object 7 is temporarily adhered and then peeled when it is desired to change a place to be adhered. For example, polyvinyl alcohol resin, polyvinyl ether resin, water-soluble resin such as cellulose resin, polyester resin, urethane resin,
Examples include hot melt resins such as polyamide resins, EVA (ethylene-vinyl acetate copolymer) resins, and polyolefin resins.

Next, the marking sheet 6 of the present invention will be described in more detail using the method for producing a double mark of the present invention in which the following steps (1) to (4) are sequentially performed.

(1) The coating 4 is cut from the colored heat-adhesive layer 3 side of the marking sheet 6 which can be temporarily adhered, without cutting the support 1 (FIG. 5). (2) The unnecessary portion of the film 4 is peeled off from the support 1 (FIG. 6), and tackiness is imparted to the colored heat-adhesive layer 3 (desired pattern portion) that can be temporarily adhered. (3) Colored heat-adhesive layer 3 capable of temporary adhesion and adherend 7
They are superposed so that and face each other, and temporarily adhered to the adherend 7 (FIG. 7), and the support 1 is peeled off (FIG. 8). (4) The colored layer 2 in the portion whose color is to be changed is peeled off (FIG. 9) and thermocompression bonded (FIG. 10).

In this case, it is necessary that the film 4 can be easily peeled off after cutting, and that it can be peeled between the colored layer 2 at a portion whose color is desired to be changed and the colored heat-adhesive layer 3 which can be temporarily adhered. That is, before thermocompression bonding, the layer between the support 1 and the colored layer 2 and the layer between the colored layer 2 and the colored thermoadhesive layer 3 that can be temporarily adhered can be peeled off. It is characterized in that it becomes difficult to separate the layer from the colored heat-adhesive layer 3 capable of temporary adhesion.

If the layer between the support 1 and the colored layer 2 is difficult to be peeled off before the thermocompression bonding, not only the unnecessary portion of the film 4 cannot be peeled off but also the support 1 cannot be peeled off particularly after the temporary adhesion. , I can't get the desired pattern. Also,
If the unnecessary film 4 can be peeled off, before the temporary adhesion,
You can check the outline of the pattern to be attached. further,
A double mark cannot be obtained unless the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered are separated from each other. In addition, after thermocompression bonding, it is difficult to peel the interlayer between the colored layer 2 and the colored thermal adhesive layer 3 that can be temporarily bonded. If peeling occurs between these layers, a problem such as peeling during use occurs. This is because the commercial value is significantly reduced.

Further, in producing the double 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.

The adhesive force between the support 1 and the colored layer 2 in contact with the support 1. : Adhesive strength between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered. : Adhesive strength between the layers of the colored heat-adhesive layer 3 that can be temporarily adhered and the adherend 7.

After cutting, when the film 4 is peeled from the support 1 (FIGS. 5 to 6) and after temporary adhesion, the support 1 is removed.
It is preferable that the relationship of the adhesive force between the respective layers at the time of peeling (see FIG. 7 to FIG. 8) be ≦≦. When it is <, peeling is likely to occur between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered, and the workability is poor. Also, <
If so, it is easy to peel between the adherend 7 and the colored heat-adhesive layer 3 that can be temporarily adhered, and it becomes difficult to peel between the colored layer 2 and the colored heat-adhesive layer 3 that can be temporarily adhered. Workability is extremely poor.

After thermocompression bonding (FIG. 10), it is preferable that all layers become difficult to peel off. This is because if the layers are easily peeled off after thermocompression bonding, the layers to be adhered after the sticking are likely to be peeled off during use and the use cannot be endured.

In the above description, the case where the entire film 4 of the unnecessary portion is peeled off has been described. However, only the colored thermal adhesive layer 3 (FIG. 11) which can temporarily bond the unnecessary portion is peeled off and the double mark is formed. It is also possible to fabricate, and it is also possible to mask the heat-bonding layer 3 capable of temporarily adhering an unnecessary portion to give adhesiveness only to a desired pattern portion to fabricate a double mark. . 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. It is also possible to provide each layer on the support 1 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. .

[0045]

According to the method for producing the marking sheet and the double mark of the present invention, a desired double mark can be obtained by one cutting and one thermocompression bonding. The step at the portion where the colored layer and the colored heat-adhesive layer that can be temporarily adhered overlap with each other is almost eliminated by thermocompression bonding to the adherend, and the appearance is very good in use. In addition, since the layers are not laminated (thermocompression bonding twice), bubbles do not enter between the marks.
