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 heat-melting adhesive layer are sequentially laminated on a plastic film support has been proposed and has been widely used in recent years. This marking sheet is
It can be attached by a simple method, and because a transparent or translucent plastic film is used as a support,
Work such as positioning has become much easier. 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 solve the above-mentioned problems, the inventors of the present invention have made various studies on the sticking method, the materials used, etc. As a result, at least two colored layers and a heat-melting adhesive layer are formed on the plastic film support. It was found that a multicolor mark which does not cause misalignment in a desired color can be obtained by a simple operation of one cutting and one thermocompression bonding by using a marking sheet in which is sequentially laminated. It was completed.

SUMMARY OF THE INVENTION The present invention provides a method for manufacturing a semiconductor device comprising the steps of:
By using a marking sheet provided with a coating formed by sequentially laminating at least two colored layers and a heat-melting adhesive layer in order from the support side, a desired color, and
A multicolor mark can be obtained by a simple operation.

As shown in FIG. 1, the marking sheet 5 of the present invention is a film obtained by sequentially laminating a first colored layer 21, a second colored layer 22 and a heat-melting adhesive layer 3 on a support 1. 4 has a laminated structure. 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 comprises sequentially performing the following steps (1) to (7) using the marking sheet 5 (FIG. 3) of the present invention described above.

(1) The coating 4 is cut from the side of the heat-melting adhesive layer 3 of the marking sheet 5 without cutting the support 1 (FIG. 4). (2) Peel off at least the heat-melting adhesive layer 3 of the unnecessary portion (FIG. 5). (3) Peel off the film 4 of the portion whose color is to be changed from the support 1 (FIG. 6). (4) At least one layer 21 of the colored layer of the film (b) peeled off in the process of (3) is peeled off entirely or partially (FIG. 7). (5) The surface of the film (b) obtained by the steps (4) opposite to the heat-melting adhesive layer 3 is attached to a desired position on the support 1 (FIG. 8). (6) The heat-melting adhesive layer 3 and the adherend 7 are superposed so as to face each other (Fig. 9) and thermocompression bonded (Fig. 10). (7) The support 1 is peeled and removed (FIG. 11).

In this method, it is possible to change the color by peeling off the film 4 of the portion whose color is to be changed from the support 1, and further peeling off one of the colored layers of the film 4, and then heat A multicolor mark can be obtained by pressure bonding. Here, by peeling and removing at least the heat-melting adhesive layer 3 of the unnecessary portion, the film 4 of the unnecessary portion is prevented from being transferred to the adherend 7. Further, if the entire unnecessary portion of the film 4 is peeled and removed, the contour of the pattern to be attached can be confirmed before the attachment.

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 positioning when it is attached 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 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 accurately cut out without causing 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 at the time of cutting or peeling off the film 4 on the unnecessary portion. Since it is heated from above, it is better not to be too thick. For this reason, it is generally 25 to 2 although it depends on working conditions and materials.
The one having a thickness of about 50 μm is used.

Further, when the film 4 is peeled from the support 1 after cutting, it is necessary to have an appropriate adhesive force with the colored layer. Therefore, depending on the support used,
It is preferable to perform an appropriate mold release treatment or subbing treatment on the support. 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 coloring layer 21 and the second coloring 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 separated when they are cut between the adjacent layers. As the tackiness, the second layer which is in contact with the interlayer between the colored layers and the heat-melting adhesive layer 3 when being cut is cut.
The layer with the colored layer 22 does not peel or fall off, and at least the heat-melting adhesive layer 3 in the non-adhered portion (unnecessary portion) is peeled off, or the layer between the colored layers in the portion whose color is to be changed is peeled. When doing, it is preferable that it can be easily worked. 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.

Furthermore, it is preferable that the layers between the colored layers and the layer between the heat-fusible adhesive layer 3 and the second colored layer 22 in contact with the layers are firmly bonded 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 is a method in which the heat-meltable adhesive layer 3 and the second colored layer 22 in contact therewith are firmly melt-bonded.

The thicknesses of the first colored layer 21 and the second colored layer 22 are such that the coating film strength is not lost, and after adhesion, 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 layers, the dyes are added to the coloring layers. 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, when a fabric 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 is not dyed in the coloring layer and the color tone of the mark is not changed. Layers can also be provided (Japanese Patent Laid-Open No. 7-83242)
No. 26479). Although this barrier layer may be provided anywhere, it is particularly effective to provide it between the heat-melting adhesive layer 3 and the second coloring layer 22 which is in contact therewith because the unnecessary coloring layer is peeled off and removed.

The pressure-sensitive adhesive layer 6 used in the above may be any substance having a slight pressure-sensitive adhesive property at room temperature, and it is necessary for the pressure-sensitive adhesive layer 6 to firmly bond the colored layers 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 the colored layers at the portions whose colors are to be changed are peeled off from each other. If it remains on the colored layer that becomes the surface when peeled, it is preferable to use a resin that can be easily peeled from the support 1 after thermocompression bonding. In addition, we put hardening agent in microcapsule,
It is also possible to mix it with a resin and cure it by applying pressure to break the microcapsules. 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-melting adhesive layer 3, a material having good adhesion may be selected depending on the type of the adherend. Those that do not block at room temperature and have no tackiness are preferably used. For example, one or more of vinyl-based copolymers, olefin-based resins, polyamide-based resins, urethane-based resins, polyester-based resins, epoxy-based resins and phenol-based 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 thickness of the heat-melting adhesive layer 3 varies depending on the adherend, but if the adherend is a fiber 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.

If desired, the heat-melting adhesive layer 3 may contain a coloring agent.

Next, the marking sheet of the present invention will be described in more detail using the method for producing a multicolor mark of the present invention in which the following steps (1) to (7) are sequentially performed.

(1) The coating 4 is cut from the marking sheet 5 from the heat-melting adhesive layer 3 side without cutting the support 1 (FIG. 4). (2) The unnecessary portion of the film 4 is peeled and removed (FIG. 5). (3) Peel off the film 4 of the portion whose color is to be changed from the support 1 (FIG. 6). (4) The first colored layer 21 of the colored layer of the film (b) peeled off in the steps of (3) is peeled off entirely or partially (FIG. 7). (5) The surface of the film (b) obtained by the steps (4) opposite to the heat-melting adhesive layer 3 is attached to a desired position on the support 1 (FIG. 8). (6) The heat-melting adhesive layer 3 and the adherend 7 are superposed so as to face each other (Fig. 9) and thermocompression bonded (Fig. 10). (7) The support 1 is peeled and removed (FIG. 11).

In this case, it is preferable that the coating film 4 in the unnecessary portion can be easily peeled and removed after cutting, and further the peeling can be performed between the colored layers in the portions where the color is desired to be changed. That is, before thermocompression bonding, the support 1 and the first colored layer 21 in contact therewith
And the colored layers can be peeled from each other, and the thermo-compression bonding makes it difficult to peel the colored layers from each other.

Before thermocompression bonding, the support 1 and the first
If it is difficult to peel off the layer between the colored layer 21 and the colored layer 21, not only the unnecessary portion of the film 4 cannot be peeled and removed, but especially, the portion of the film 4 whose color is desired to be changed cannot be peeled off, so that a desired pattern cannot be obtained. Further, if the film 4 of the unnecessary portion can be peeled off, the pattern to be attached can be confirmed at the stage before the attachment. At this time, the heat-melting adhesive layer 3 and the second colored layer 22 in contact therewith may be difficult to peel off. Further, after thermocompression bonding, the support 1 is peeled off and the colored layers (the first colored layer 21 and the second colored layer 2) in contact with the support 1 are separated.
It is necessary that the layer between (2) and the colored layer should be peelable, and that the layers between the colored layers should be difficult to peel. This is because if peeling occurs between the colored layers, problems such as peeling will occur during use and the commercial value will be significantly reduced.

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.

The adhesion between the support 1 and the colored layer in contact with the support 1. : Adhesive force between the colored layers. : Adhesive force between layers of the heat-melting adhesive layer 3 and the second colored layer 22 in contact therewith. : Adhesive force between layers of the heat-melting adhesive layer 3 and the adherend 7.

When the unnecessary portion of the film 4 is peeled from the support 1 after cutting (FIGS. 4 to 5), the adhesive force between the layers is preferably ≦≦. >
In that case, the coating film 4 is difficult to be peeled from the support 1, and peeling occurs between layers in the middle, resulting in poor workability. Further, when peeling off the colored layer of the portion whose color is to be changed (FIGS. 6 to 7),
When it is>, the heat-melting adhesive layer 3 and the second colored layer 22 that is in contact with the heat-meltable adhesive layer are easily peeled off from each other, and they are not easily peeled off from each other between the colored layers, so that workability is extremely deteriorated.

After thermocompression bonding (FIG. 10), <<
It is preferably (,,). ≧ (,,,
In such a case, when the support 1 is peeled off, the pattern that should have been transferred to the adherend is peeled off entirely or partially and is peeled off together with the support 1, so that the desired pattern cannot be obtained. .

In the above description, the case where the entire film 4 of the unnecessary portion is peeled off has been described. It is also possible to peel off one colored layer 22 (FIG. 13) to produce a multicolor mark. At this time, it is preferable that the adhesive force between the layers is appropriately adjusted to facilitate the work.

These layers can be laminated by dispersing or dissolving them in a solvent or the like, or by heat-melting them and sequentially coating them on a support. In addition, a colored layer having 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 on the temporary support, The heat-melting adhesive layer 3 alone or a desired coloring layer 22 laminated on the heat-melting adhesive layer 3 by a known method is used as a coloring layer (second coloring layer 22 or first coloring layer) on the support 1. 21) and the heat-melting adhesive layer 3 or the colored layer 22 on the heat-melting adhesive layer 3 may be laminated so as to face each other. It is also possible to provide each layer on a separate 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. .

[0041]

According to the marking sheet and the method for producing a multicolor mark of the present invention, a desired multicolor mark in which a pattern shift does not occur 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 lamination (two or more times of thermocompression bonding) is not performed, bubbles do not enter between the mark layers.
