Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basic thermal transfer print marking sheet on which a desired character or pattern is printed and cut into a predetermined shape, which is then placed on an adherend such as clothing and pressed and heated. TECHNICAL FIELD The present invention relates to a thermal transfer print marking sheet that is used as a thermal adhesive mark by adhering together, a manufacturing method thereof, and a thermal adhesive mark with a surface design.

[0002]

2. Description of the Related Art For example, when a predetermined character such as a jersey number, a name, an emblem, or a pattern is displayed on a base cloth (also referred to as an adherend) such as sports goods or other clothing or bags A cloth cut into a shape is often sewn to a base cloth. However, in recent years, a method of adhering a marking sheet obtained by cutting a sheet of a predetermined color into a predetermined shape to the base fabric instead of sewing the cut base fabric is used.

[Prior Art 1] As a marking sheet using a transfer method, a heat-sensitive adhesive layer is laminated on a release sheet, and a sheet colored by kneading a pigment into PVC or acrylic resin is colored thereon. Is known as a colored layer, and a marking sheet having a structure in which a support is provided thereon is known. Such a marking sheet, after removing the release sheet and cutting it into the desired characters and figures, removes unnecessary parts (also called dust removal) and places it on the base fabric, and pressurizes and heats it to bond it. After that, the support is peeled off, whereby marking is made on the base cloth by transfer.

[Prior Art 2] A base material layer of a base material sheet in which a support and a base material layer (having a function of an adhesive for hot melt) are laminated as a transfer sheet for coping with multiple colors. After printing a multicolor pattern / design with a color copier, etc., cutting this base sheet according to the printed pattern, etc., and thermally bonding the base layer to an adherend such as clothing,
There is a method of transferring a design / design to an adherend such as the clothing by peeling the support.

As described above, anyone can easily perform a desired display simply by cutting the marking sheet into a shape for displaying a predetermined character, a design or the like and thermally bonding it to the adherend. For this reason, it is not necessary to sew a cloth cut into a predetermined shape to the base cloth, and the work can be performed easily, and by using this marking sheet, the same finish as a skilled craftsman can be obtained.

[0006]

However, a colored marking sheet obtained by kneading a pigment or the like into PVC or the like as shown in the prior art 1 can obtain only a single color sheet, so that a multicolored character When obtaining a combination or a pattern, the user needs to combine the monochromatic marking sheets. That is, it is necessary to cut out a plurality of marking sheets each having a different color according to the design to be displayed, accurately arrange them according to the design to be displayed, etc. It is difficult and the work is complicated. Further, when performing multi-color display, marking sheets of multiple colors are required, but since the number of colors is limited, it may not be possible to perform desired color display, and it may be difficult to use. is there.

A transfer sheet printed by color copying or the like as shown in the prior art 2 in order to support multi-color display has no concealing property for the color material, and is affected by the material color. It has the drawback of being less robust. Further, in the field of stickers and the like, there is a problem that washing resistance and dry cleaning resistance are not sufficient.

The present invention has been made in view of the above problems, and a thermal transfer print marking sheet capable of easily displaying multiple colors by thermal transfer print or the like, excellent in concealing property, and resistant to washing and dry cleaning, An object of the present invention is to provide a stable manufacturing method of the thermal transfer print marking sheet.

[0009]

In order to solve the above-mentioned problems, the thermal transfer print marking sheet according to claim 1 is used as a heat-bonding mark by being heated and pressed to adhere to an adherend such as clothing. , A thermal transfer print marking sheet in which an adhesive layer for hot melt and a base material layer are laminated in this order on the surface of a support layer, and a predetermined pattern, character, figure or the like can be printed on the surface of the base material layer. And the adhesive force between the surface of the support layer and the adhesive layer for hot melt is 5
It is characterized by being ~ 150 g / 25 mm.

Conventionally, a single color heat transfer print marking sheet was used, and there was a problem of poor designability. However, a predetermined pattern, character, figure or the like was formed by printing on the surface of the single color heat adhesive mark, and a predetermined pattern was formed. By cutting into the shape of the heat-bonding mark, various heat-bonding marks for multicolor display can be easily formed regardless of the use of the monochromatic base material layer.

However, in this case, after the hot-melt adhesive and the base material layer are laminated on the surface of the support layer (the surface on which the hot-melt adhesive layer is laminated), a pattern or the like is printed on the base material layer. , Cut into a predetermined shape along the pattern, etc., and peel off this heat-adhesive mark part (meaning the base material layer with the adhesive layer for hot melt on one side and the printing layer on the other side) from the support layer. It is necessary to heat-bond to the adherend such as clothing. When the adhesive force between the surface of the support layer and the adhesive layer for hot melt is less than 5 g / 25 mm, the support layer and the hot melt adhesive are used when cutting small letters or sharp corners of a printed pattern. There is a problem that it may be peeled off or lifted up between and, and wrinkles may occur, and when the adhesive force exceeds 150 g / 25 mm, the heat-adhesive mark portion is stuck on the application film on the print layer. It becomes difficult to peel it off from the support layer.

In the thermal transfer print marking sheet according to a second aspect of the present invention, the adhesive force between the surface of the support layer and the hot melt adhesive layer is high when the thermal transfer print marking sheet is wound into a coil. Is larger than the adhesive force between the back surface of the support layer and the base material layer.

In the step of producing the thermal transfer print marking sheet according to claim 1, an adhesive layer for hot melt and a base material layer are laminated on a support layer and wound into a coil to form an adhesive layer for hot melt. And the back surface of the support layer (referred to as the surface to which the hot melt adhesive layer is not attached in the above step), or the base material layer and the back surface of the support layer may come into contact with each other for storage. This thermal transfer print marking sheet wound in a coil shape needs to be able to be smoothly developed in the processes such as printing and cutting.

When the adhesive force between the back surface of the support layer and the base material layer is larger than the adhesive force between the surface of the support layer and the adhesive layer for hot melt, it becomes impossible to develop due to blocking. There may be a problem of peeling between the body layer and the hot melt adhesive layer. The releasability of the back surface of the support layer is adjusted by a release treatment such as coating with a silicone release agent.

The thermal transfer print marking sheet according to claim 3 is used as a thermal adhesive mark by adhering to an adherend such as clothing under pressure and heat, and is used as a thermal adhesive mark, and an adhesive layer for hot melt is provided on the surface of the support layer. A thermal transfer print marking sheet with a surface protective layer in which a base material layer and a surface protective layer are laminated in this order, and the adhesive force between the back surface of the surface protective layer and the base material layer is 1 g / 25 mm or more. And less than the adhesive force between the surface of the support layer and the hot melt adhesive layer.

An adhesive layer for hot melt, a base material layer and a surface protective layer are laminated in this order on the surface of a support layer, and a thermal transfer print marking sheet before printing / cutting is wound into a coil. After being stored, it is developed in the next process of printing and cutting. If the adhesive force between the back surface of the surface protection layer and the base material layer is less than 1 g / 25 mm, the surface protection layer peels off from the base material layer and becomes wrinkled in the above-mentioned steps such as winding, storage and printing. It may cause scratches. On the other hand, if the adhesive strength between the back surface of the surface protective layer and the base material layer is equal to or more than the adhesive strength between the hot melt adhesive and the surface of the support layer, when the surface protective layer is peeled from the base material layer in a later step, There is the problem of delamination between the support layer and the hot melt adhesive.

In the thermal transfer print marking sheet according to claim 4, the surface of the surface protective layer to be bonded to the base material layer has a shape corresponding to the surface design formed on the base material layer. Is characterized by. On the surface of the surface protective layer to be laminated with the base material layer, a shape corresponding to the surface design (referred to as the shape of the surface) such as gloss and matte to be formed on the base material layer is formed. Thereby, by pressing the surface protective layer against the base material layer, and bonding while heating,
A surface design can be formed on the surface of the base material layer before printing. As a result, a unique effect such as gloss and matte can be imparted to the next printed surface. When the surface protection layer is coated with the base material layer, pressurization / heating is not required.

A method for producing a thermal transfer print marking sheet with a protective layer (also referred to as a protective sheet with a protective layer) according to claim 5 is a heat-adhesive mark which is adhered to an adherend such as clothing by applying pressure and heat. A method for producing a marking sheet with a protective layer which is used and has a hot melt adhesive layer, a base material layer and a surface protective layer laminated in this order on the surface of a support layer, wherein the surface of the support layer is A laminate A in which an adhesive layer for hot melt is laminated and a laminate B in which the base material layer is laminated on the back surface of the surface protective layer are produced, and the adhesive layer for hot melt in the laminate A and the laminate are prepared. It is characterized in that the base material layer of the body B is face-to-face and bonded.

In the method for producing a marking sheet with a surface protective layer, in which an adhesive layer for hot melt, a base material layer, and a surface protective layer are sequentially laminated on a support layer, an intermediate laminate in which three layers are laminated is used. Although a process of handling occurs, two intermediate laminates of the laminate A and the laminate B are created as described above, and these are laminated to treat a two-layer laminate as an intermediate laminate. Is easier and easier to work with.

A method of laminating the laminate A and the laminate B according to claim 6 is dry lamination or thermal lamination. If the hot melt adhesive is sticky, dry lamination is performed, and if it is not sticky, heat lamination is performed. The laminating method is selected depending on the state of the hot melt adhesive, the process is simplified without using a solvent, and a clean environment can be maintained.

According to a seventh aspect of the present invention, there is provided a marking sheet for thermal transfer printing, wherein a hot melt adhesive layer is laminated on the surface of a support layer and wound into a coil to form a laminate A.
In the step of producing, the adhesive force between the surface of the support layer and the hot melt adhesive layer is greater than the adhesive force between the back surface of the support layer and the hot melt adhesive layer, To do.

When the laminated body A is first laminated and then the laminated body A is attached to the laminated body B following the manufacturing process of the laminated body B, there is a step in which only the laminated body A is wound into a coil shape. . At this time, the back surface of the support layer and the hot melt adhesive layer contact each other. Therefore, by making this adhesive force smaller than the adhesive force between the surface of the support layer and the hot melt adhesive layer, the laminate A in the next step is formed. Can be deployed smoothly. In the opposite case, if the laminate A wound into a coil is blocked and is forcibly separated, the surface of the support layer and the adhesive layer for hot melt may be separated.

In the method for producing a marking sheet for thermal transfer printing according to claim 8, in the step of producing a laminate B by laminating a base material layer on the back surface of the surface protective layer and winding it into a coil, the surface protective layer is formed. The adhesive force between the back surface of the substrate and the base material layer is greater than the adhesive force between the surface of the surface protective layer and the base material layer.

When the laminate B is first laminated and then the laminate B is attached to the laminate A following the step of producing the laminate A, only the laminate B is wound into a coil. There is. At this time, when the adhesive force between the back surface of the surface protective layer and the base material layer is smaller than the adhesive force between the surface of the surface protective layer and the base material layer, the laminated body B wound into a coil is blocked, and it is impossible. If it is pulled away, the back surface of the surface protective layer may be peeled off or may not be peeled off between the base material layer.

The thermal adhesive mark with surface design according to claim 9 has a surface design in which an adhesive layer for hot melt, a base material layer and a printing layer are laminated and adhered to an adherend such as clothing in this order. An application film is attached to the print layer of the thermal transfer print marking sheet according to claim 1, which is a heat-adhesive mark, is printed and cut, and unnecessary portions are removed, the support layer is peeled off, and an adherend such as clothing is attached. After applying heat and pressure to adhere to the surface of the heat-adhesive mark from which the application film has been peeled off, the printed surface of the heat-adhesive mark having a surface design and the design surface of the design sheet having releasability are overlaid. Characterized in that the surface design is transferred to the printing layer by reheating and pressurizing to a temperature which is equal to or higher than the softening temperature of the base material layer and is equal to or lower than a temperature obtained by adding 60 ° C. to the softening temperature. .

The surface of the heat-bonding mark adhered to an adherend such as clothing using the heat transfer print marking sheet according to the first aspect usually shows the surface shape of an application film or a heat press board. On the surface of this heat-bonding mark, a surface design, for example, a matte-tone design, and a design sheet that is a sheet having releasability from the base material layer is placed on the surface of the heat-bonding mark, and then heated and pressed again, whereby the heat-bonding is performed. A new shape (matte, gloss, etc.) is formed on the surface of the mark. Since the surface of the design sheet that is in contact with the base layer is subjected to a mold release treatment, it can be easily peeled from the surface layer after transfer. In addition, if the reheating temperature is not higher than the softening temperature of the base layer, the surface design is not transferred, and if the temperature exceeds the softening temperature of the base layer plus 60 ° C., the base layer Prints flow or are destroyed, or the base material layer is pushed into an adherend such as clothing, resulting in poor concealability.

BEST MODE FOR CARRYING OUT THE INVENTION A thermal transfer print marking sheet (also referred to as a basic marking sheet) of the present invention, a thermal transfer print marking sheet with a protective layer (also referred to as a protective sheet with a protective layer), a manufacturing method thereof, and a surface design An embodiment of the heat-bonding mark will be described with reference to the drawings.

First, as shown in the partial cross-sectional view of FIG. 1, the structure of the thermal transfer print marking sheet (basic marking sheet 20) according to the present invention has a peelable surface of the support layer 3 (for hot melt). On the surface on which the adhesive layer is laminated), the hot-melt adhesive layer 2 using the hot-melt adhesive and the base material layer 1 are laminated in this order. The thermal transfer print marking sheet (print marking sheet 21) is printed by providing the printing layer 5 on the surface of the basic marking sheet 20.

The support layer 3 is an adhesive layer 2 for hot melt.
And the base material layer 1 are supported. That is, until the printing marking sheet 21 is adhered to the adherend such as clothes or bags,
The hot melt adhesive layer 2 is protected and each layer such as the relatively soft base material layer 1 is supported. Further, since the support layer 3 needs to be peeled off when the heat-bonding mark portion 24 is adhered to an adherend such as clothing, the surface of the support layer 3 can be peeled off from the hot-melt adhesive layer 2. It is surface-treated so that it adheres with a predetermined force.

The support layer 3 is not particularly limited as long as it can protect the hot melt adhesive layer 2 and can be peeled from the hot melt adhesive layer 2 with a predetermined force. For example, polypropylene (PP) , Polyvinyl chloride (PV
A release film or release paper made of C), polycarbonate (PC), polyethylene terephthalate (PET), or the like is used, and a PET film is often used. As such a PET film, a commercially available product can be used, and the product name “Gloss PET75X1-TF” (manufactured by Nipper Co., Ltd.) can be used, although it is not particularly limited. From the viewpoint of handleability, the thickness of the support layer 3 is generally appropriately set within the range of 25 μm or more and 200 μm or less, and a thickness of about 100 μm is generally used.

The hot-melt adhesive layer 2 is an adhesive for hot-melt, and melts and flows by heat and pressure during thermocompression bonding so that the heat-adhesive mark portion 24 adheres to the adherend such as clothing (not shown). No.) can be melt-bonded. The hot-melt adhesive is not particularly limited as long as it can be hot-melted and can adhere to clothing and the like and the base material layer 1, but a urethane-based adhesive is preferably used. As the adhesive layer for hot melt, it is preferable to use an adhesive for hot melt having a flow starting temperature in the range of 50 ° C. or higher and 120 ° C. or lower in order to obtain a sufficient adhesive force to an adherend. If the flow starting temperature is lower than 50 ° C., the composition becomes sticky at room temperature, the workability is poor, the cohesive force is weak, and the adhesive strength is low. On the other hand, when the flow starting temperature is higher than 120 ° C., there is a tendency that the adhesion is deteriorated due to insufficient melting and the adhesion is weakened.

The hot melt adhesive is selected so that the flow starting temperature thereof is lower than the softening temperature of the base material layer 1 (polyurethane resin or the like), for example, "No. 557".
6 ”(product number; manufactured by No Tape Industrial Co., Ltd.) can be used.

The thickness of the hot melt adhesive layer 2 is
Although not particularly limited, the thickness of the hot-melt adhesive layer 2 is preferably in the range of 20 μm or more and 100 μm or less in order to obtain a sufficient adhesive force to the adherend. When the thickness is less than 20 μm, the adhesive strength is remarkably reduced, and even when it is more than 100 μm, the effect of improving the adhesive strength corresponding to the increase in the thickness of the adhesive layer 2 for hot melt cannot be obtained and the texture is deteriorated. , Tend to be hard.

The base material layer 1 is mainly composed of a polyurethane resin having a softening temperature in the range of 80 ° C. or higher and 150 ° C. or lower, for example, and is subjected to thermal transfer printing on its surface to display an arbitrary color. It is possible. The softening temperature of the base material layer 1 is set to be higher than the flow starting temperature of the hot melt adhesive used in the hot melt adhesive layer 2. This is because the base material layer 1 is not deformed when the heat-bonding mark portion 24 is heat-welded to an adherend such as clothing. When the softening temperature of the polyurethane resin used for the base material layer 1 is less than 80 ° C., the ink ribbon sticks to the base material layer 1 during thermal transfer printing of a design, design, etc. on the base material layer 1, which hinders printing. May occur. on the other hand,
If the softening temperature of the polyurethane resin exceeds 150 ° C., the ink adhesion tends to decrease.

As such a base material layer 1, a commercially available polyurethane resin may be selected and a softening agent and a curing agent may be added to adjust the softening temperature. For example, urethane resin "Resamine ME-44LP" (product number; manufactured by Dainichiseika Kogyo KK, softening temperature = 130 ° C) as a main component, acrylic resin "UAC-43B" (produced by Special Coloring Company), ink "M"
U6091 (white ink) "(manufactured by Dainichiseika Co., Ltd.) and the like to adjust the softening temperature.

The print layer 5 has a thermal adhesive mark 23 (see FIG. 2).
(E)) is a layer for forming pictures, characters, figures, etc. of multicolor display, and at the same time as full-color printing by a thermal transfer printing / cutting machine, depending on the picture or design, base layer 1, hot melt It is cut together with the adhesive layer 2 for a predetermined shape. For this thermal transfer print / cut machine,
For example, "COLER CAMM" manufactured by Roland DG
PC 600 "can be used. In this way, it is possible to provide a thermal transfer print marking sheet having a print layer (also referred to as a marking sheet 21 having a print layer), which has excellent ink adhesion and does not cause print drop after washing or dry cleaning.

In the present embodiment, the method of laminating each layer of the marking sheet 21 with the printing layer is not particularly limited, and various methods such as coating, laminating and a method using an extrusion device such as a T-die method. Can be adopted. Referring to FIG. 2, the marking sheet 21 with a printing layer according to the present invention is adhered to an adherend 8 such as clothing to obtain a heat-adhesive mark 2.
The procedure for setting 3 will be described.

As shown in the partial cross-sectional view of FIG. 2 (a), the basic marking sheet 20 comprises a support layer 3 (usually a PET film) and a hot melt adhesive layer 2 and a base material layer 1 on the surface thereof.
And are laminated in this order.

As shown in FIG. 2B, a printing layer 5 for multicolor display is printed on the surface of the base material layer 1 of the basic marking sheet 20 so as to display a predetermined pattern or design. Thermal transfer print marking sheet (marking sheet 21 with a printing layer), and at the same time, the base material layer 1 and the adhesive layer 2 for hot melt are cut according to the above-mentioned pattern or design (printing / cutting means are not shown, and a support is also provided). Layer 3 is not cut). Unnecessary portions (portions not used as the heat-bonding mark portions 24) of the cut marking sheet 21 with the print layer are peeled off from the support layer 3 (not shown).

As shown in FIG. 2C, the application film 6 is attached to the surface of the printing layer 5 of the marking layer-equipped marking sheet 21 from which unnecessary portions are removed, and the marking with the printing layer is applied. After forming the sheet 22, the support layer 3 is peeled off from the hot melt adhesive layer 2.

Next, as shown in FIG. 2D, the application film 6 is attached and the support film 3 is peeled off.
(Also referred to as ") is placed on the surface of the adherend 8 such as clothing with the adhesive layer 2 for hot melt facing each other. This adherend 8
The heat-adhesive mark portion 30 with application is sandwiched between the heat press plates 12 and 12 ′, and heated and pressed to melt the adhesive layer 2 for hot melt, and the heat-adhesive mark portion 30 with application is attached to the adherend 8. To glue. The heat-bonding mark portion with application 30 bonded to the adherend 8 is taken out from the heat press plates 12 and 12 'as shown in FIG. 2 (e), and the application film 6 is peeled off to complete the heat-bonding mark 23. .

The application film 6 is attached to the printed layer 5 of the base material layer 1 when the heat-bonding mark portion 24 is heat-bonded to an adherend such as clothing, and the heat-bonding mark portion 2 is applied.
4 for protecting and supporting 4, does not impair the thermal adhesiveness of the thermal adhesive mark portion 24 to the adherend, and has sufficient heat resistance and dimensional stability when thermally adhered. The application film “AP-S” (trade name) manufactured by Lintec Co., Ltd. is preferably used, though not particularly limited. Application film 6
From the above viewpoint, the thickness of the
It is preferably in the range of m or less, 70 μm or more,
More preferably, it is in the range of 150 μm or less.

As the hot press machine, an iron, a manual press machine or the like may be used easily. The adherend 8 may have various shapes and uses / fields such as clothing, bags, banners, patches, and hats.

The heat-bonding conditions for heat-bonding the heat-bonded mark portion 23 to the adherend 8 are as follows: the flow starting temperature of the hot-melt adhesive layer 2 used, the softening temperature of the base material layer 1, and the like. Although it is appropriately set depending on the layer thickness, the thickness and material of the base material layer 1, etc., it is not particularly limited, but it is preferable to perform hot pressing in a temperature range of 110 ° C. or higher and 180 ° C. or lower.

Next, the marking sheet with a printing layer, the thermal transfer printing marking sheet with a surface protective layer (also referred to as a marking sheet with a protective layer), the method for producing the same and the thermal adhesive mark with a surface design according to the present invention will be described in detail. .

Example 1 First, Example 1 relating to the adhesive force between the support layer 3 and the hot melt adhesive layer 2 of the marking sheet 21 with a printing layer will be described. The basic marking sheet 20 whose partial sectional view is shown in FIG.
Release-processed PET film commercially available as "PET7
5 × 1-TF ”(trade name; manufactured by Nipper Co., Ltd., 75 μ
m) was used, and "No. 5576" (trade name; manufactured by No-Tape Kogyo Co., Ltd., flow starting temperature 50 ° C.) was used as a hot-melt adhesive, and "Resamine ME-" was used as the base material layer 1 on this upper surface.
44LP "(trade name; manufactured by Dainichiseika Kogyo Co., Ltd., a one-component polyurethane resin having a softening temperature of 130 ° C.) was laminated in this order.
The adhesive layer 2 for hot melt had a thickness of 40 μm, and the base material layer 1 had a thickness of 20 μm.

The adhesive force between the support layer 3 of the basic marking sheet 20 and the hot-melt adhesive layer 2 is adjusted by the degree of release treatment of the surface of the support layer 3 to which the hot-melt adhesive is applied. Experimental Examples 1-4, Comparative Experimental Examples 1 and 2
Were prepared and the cutting suitability and application properties were evaluated, and the results are shown in Table 1. In Table 1, the cutting suitability is indicated as "cut suitability" and the application property is indicated as "appliability". The degree of release treatment of the support layer 3 is adjusted by using, for example, silicon or melamine alkyd as a release agent, depending on its type, coating density, additives and the like.

The measuring method of the adhesive force is JIS K-677.
A tensile tester “0116S (model number)” manufactured by Aigo Engineering Co., Ltd. was used as a measuring machine based on 2. The cutting suitability means that while printing on the surface of the base material layer 1 of the basic marking sheet 20, The workability when cutting into a predetermined shape (the support layer 3 is not cut) means that the necessary portion (heat-adhesion mark portion) is the support layer 3
It refers to the extent to which it is cut without peeling and unnecessary portions can be peeled off easily. Further, the application property means a degree to which the necessary part follows the application film 6 when the application film 6 is attached to the necessary part and peeled from the support layer 3 together with the necessary part.

[0049]

[Table 1]

(Note 1) The adhesive strength * 1 in Table 1 indicates the adhesive strength between the hot melt adhesive layer 2 and the support layer 1 (unit =
g / 25 mm). (Note 2) In the columns of cutting suitability and applicability * 2 in Table 1, ◎ is good without any problems, ○ is good, △ is good in general, and × shows problems (visual inspection). by).

From the data in Table 1, the cutting suitability and the applicability tend to be opposite with respect to the change in the adhesive force between the hot melt adhesive layer and the support layer.

In Experimental Examples 1 to 4, the adhesive force was 5 g / 2.
The amount was varied from 5 mm to 150 g / 25 mm, but in this range, the cutting suitability and application properties are generally in a good range or higher. Comparative Experimental Example 1 has an adhesive force of 2 g / 25 mm, and has an application property, that is, it is easy to peel off the application film-attached thermal adhesive mark portion 22 from the support layer 3 after printing / cutting, but cutting. Suitability, that is, when cutting after printing, peeling or floating may occur between the support layer 3 and the hot-melt adhesive layer 2 in the details of the pattern, small characters, or sharp corners of the pattern. In Comparative Experimental Example 2, the adhesive strength is 200 g / 25 mm and the cutting suitability is good, but the application property is that the cut thermal adhesive mark portion 24 cannot be peeled off from the support layer 3, and the application It may peel off between the film 6 and the base material layer 1.

In the manufacturing process of the above basic marking sheet 20, the hot melt adhesive layer 2 is formed on the support layer 3.
There is a process of laminating and winding in a coil shape, at this time,
The adhesive force between the back surface of the support layer 3 and the front surface of the hot melt adhesive layer 2 can be calculated by measuring the adhesive force between the back surface of the support layer 3 and the hot melt adhesive layer 2.
When the sheet wound into a coil is unfolded in the next step with the adhesive force with the adhesive layer (for example, 5 g / 25 mm) being reduced, the support layer 3 with the hot melt adhesive layer is smoothly unfolded. The adhesive force can be adjusted by subjecting the back surface of the support layer 3 to a release treatment.

Example 2 An embodiment of a thermal transfer print marking sheet with a surface protective layer (also referred to as a protective sheet with a protective layer) will be described with reference to FIG. FIG. 3A shows a partial cross-sectional view of the marking sheet with protective layer 25 in which the surface protective layer 4 is attached to the surface of the basic marking sheet 20 whose partial sectional view is shown in FIG. 2A. The basic marking sheet 20 has processes such as winding, rewinding, and storage before printing / cutting. During the process, scratches are generated on the surface of the base material layer 1 or foreign matter is attached to the basic marking sheet 20 for the next printing process. In this case, ink may be removed, blocking may occur in the wound state, the back surface shape of the support layer 3 may be transferred to the base material layer 1, and air marks may be generated. Therefore, the surface protection layer 4 is releasably attached to the surface of the base material layer 1 of the basic marking sheet 20 to prevent this.

As the surface protective layer 4, a release-treated polypropylene film such as "RS-02" manufactured by Santox Co. is used. The support layer 3, the hot-melt adhesive layer 2, and the base material layer 1 were used in Example 1.
Used the same.

The adhesive force between the surface protective layer 4 and the base material layer 1 is 1 g / 25 mm or more, which is smaller than the adhesive force between the hot melt adhesive layer 2 and the support layer 3. If this adhesive strength is less than 1 g / 25 mm, the surface protective layer 4 and the base material layer 1 may float or peel off in the steps such as winding and rewinding, causing wrinkles and misalignment of printing. Sometimes.

When this adhesive force is equal to or more than the adhesive force between the hot melt adhesive layer 2 and the support layer 3, the surface protective layer 4 is peeled from the base material layer 1 in the next step (printing / cutting step). At this time, it may be peeled off between the support layer 3 and the hot melt adhesive layer 2.

When the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2 is 100 g / 25 mm (Experimental Example 3), the adhesive force between the back surface of the surface protective layer 4 and the base material layer 1 is: 20g / 25mm, 50g / 25mm, 70g / 25
In the case of mm, no peeling occurred in the laminating step in any case, and peeling of the surface protective layer 4 was easy in the printing / cutting step. Furthermore, when the adhesive force between the surface protective layer 4 and the base material layer 1 is set to 0.5 g / 25 mm, the surface protective layer 4 and the base material layer 1 are peeled off and wrinkled during the lamination and winding steps, and 120 g In the case of / 25 mm, when the surface protection layer 4 is to be peeled off in the printing / cutting process, peeling is performed between the support layer 3 and the hot melt adhesive layer 2 to print.
I couldn't cut it.

Further, by providing a surface design such as matte and matte on the surface of the surface protective layer 4 facing the base material layer 1, the surface design such as matte is provided on the surface of the base material layer 1 before printing. It can be expressed, and thus the texture such as taste and depth of printing can be adjusted.

Example 3 An example of a method of manufacturing the marking sheet 25 with a protective layer shown in FIG. 3A will be described.
The adhesive layer 2 for hot melt is formed on the surface (upper surface) of the support layer 3.
A laminated body A26 in which the base material layer 1 is laminated on the back surface (lower surface) of the surface protective layer 4 is manufactured, and the hot melt adhesive layer 2 and the laminated body B27 of the laminated body A26 are manufactured.
The base material layer 1 of 1 is faced to and bonded. In the method of sequentially laminating the hot melt adhesive layer 2, the base material layer 1, and the surface protective layer 4 on the support layer 3, a step of handling an intermediate laminated body in which three layers are laminated occurs. Since the two-layered laminate A26 and the two-layered laminate B27 are attached to each other in this manner, the intermediate laminate can be easily handled.

After the laminated body A26 is manufactured in advance, the base material layer 1 of the laminated body B27 is manufactured while the laminated body B27 is manufactured.
To the surface of the adhesive layer 2 for hot melt of the laminate A26, conversely, after manufacturing the laminate B27 in advance, while manufacturing the laminate A26, the adhesive for hot melt of the laminate A26 There is also a method in which the surface of the base material layer 1 of the laminated body B27 is bonded to the surface of the layer 2, and in this case, there is an advantage that the bonding step is two steps.

The laminate B27 produced by this production method has a urethane resin as the base material layer 1 on the back surface of a polypropylene film "RS-02" (trade name, manufactured by Santox Co.) whose surface is release-treated as the surface protection layer 4. Solution "Resamine ME-
44LP "(trade name, manufactured by Dainichiseika Kogyo Co., Ltd.) is coated, dried and wound into a coil. The “RS-02” is
The film thickness used was 0.06 mm, and the thickness of the base material layer 1 was 0.02 mm after coating and drying. "RS-
The back surface of “02” (the surface on which the base material layer 1 is laminated) is a plain surface without treatment, and the front surface is treated with silicon to ensure a predetermined releasability from the base material layer 1.

The laminated body B27 is formed by laminating the base material layer 1 on the back surface of the surface protective layer 4 and then winding it into a coil, and the surface of the surface protective layer 4 and the base material layer 1 are overlapped with each other to some extent. Although pressed, since the surface of the surface protective layer 4 is subjected to a mold release treatment such as silicon treatment, the surface of the surface protective layer 4 and the base material layer 1 do not adhere strongly to each other and easily develop,
It can be attached to the laminate A26.

When a PET film, paper or the like is used as the surface protection layer 4, both surfaces of these surface protection layers 4 need to be subjected to a mold release treatment, and this back surface (the surface to be laminated with the base material layer 1) The adhesive force with the base material layer 1 is set to be larger than the adhesive force with the surface and the base material layer 1.

The laminate A26 has a surface (the surface on which the hot-melt adhesive layer 2 is laminated) as a support layer 3 which is release-treated, and the hot-melt adhesive layer 2 formed on the PET film.
Are stacked. As a PET film that has been subjected to a mold release treatment, a 0.075 mm-thick “gloss PET 75 × 1-T”
F "(product number, manufactured by Nippers Co., Ltd.), and as the hot melt adhesive layer 2," NO. 5576 "(product number,
Notape Kogyo Co., Ltd.) was applied after drying to a thickness of 0.04 mm.

Although the surface of the support layer 3 is subjected to a mold release treatment, the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2 is the same as the surface protective layer 4 and the base material layer 1 described above. It is designed to be stronger than the adhesive strength with. This is because it is necessary to peel off only the surface protective layer 4 in the printing / cutting step after bonding the laminated body B27 in the next step. For example,
When the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2 is 100 g / 25 mm, the adhesive force between the back surface of the surface protective layer 4 and the base material layer 1 is about 50 g / 25 mm. preferable.

When the laminate A26 is manufactured first and then laminated with the laminate B27, the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2 is 100 g / 25 mm,
The adhesive force between the back surface of the surface protective layer 4 and the base material layer 1 is 50 g / 2.
In the case of 5 mm, the adhesive force between the back surface of the support layer 3 and the hot melt adhesive layer 2 and the adhesive force between the surface of the surface protective layer 4 and the base material layer 1 are the same as the back surface of the surface protective layer 4. And base material layer 1
Adhesive strength with less than 50g / mm, for example, about 20g
/ 25 mm is preferable.

When the laminate B27 is manufactured first and then laminated with the laminate A26, the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2 is 100 g / 25.
mm, the adhesive force between the back surface of the surface protective layer 4 and the base material layer 1 is 50
In the case of g / 25 mm, the adhesive force between the surface of the surface protective layer 4 and the base material layer 1 is smaller than the adhesive force between the back surface of the surface protective layer 4 and the base material layer 1, for example, about 20 g / 25 mm. Preferably.

Further, after the laminate A26 and the laminate B27 are individually laminated, the base material layer 1 and the laminate A26 of the laminate B27 are laminated.
When the adhesive layer 2 for hot melt is adhered to each other to form the marking sheet 25 with a protective layer (see FIG. 3A), it is necessary to have both of the above two requirements. In addition, this sticking is performed by dry lamination when stickiness remains on the surface of the hot melt adhesive layer 2 of the laminate A26, and when there is no stickiness, heat above the softening temperature of the hot melt adhesive is applied. Heat laminate.

The hot-melt adhesive layer 2, the base material layer 1 and the surface protective layer 4 are laminated in this order on the surface of the support layer 3, and the marking sheet 25 with the surface protective layer shown in FIG.
In the case of producing, the hot-melt adhesive layer 2, the base material layer 1 and the surface protective layer 4 are laminated in this order on the surface of the support layer 3, and each of these layers is wound into a coil shape. When taken, the adhesive force between the back surface of the support layer 3 and the surface of each layer laminated is made smaller than the adhesive force between the surface of the support layer 3 and the hot melt adhesive layer 2. This is to prevent peeling between layers that have already been laminated when the layers are rolled up in a coil shape and then developed in the next step.

Similarly, on the back surface of the surface protective layer 4, the base material layer 1,
In the case of manufacturing the marking sheet 25 with a surface protective layer shown in FIG. 3A by laminating the hot melt adhesive layer 2 and the support layer 3 in this order, the layer was laminated with the surface of the surface protective layer 4. It is preferable that the adhesive strength between the back surface of each layer and the back surface of the surface protective layer 4 is smaller than the adhesive strength between the base material layer 1.

[Embodiment 4] As another embodiment, an embodiment in which the surface design of a heat-bonding mark thermally transferred to an adherend such as clothing is improved will be described. First, the surface protective layer 4 of the marking sheet 25 with a protective layer whose partial sectional view is shown in FIG. 3 (a) is peeled off (see FIG. 3 (b)) and printed to print the base material layer 1 and the adhesive for hot melt. Cut layer 2 and according to the design,
The unnecessary portion is removed (also referred to as scrap removal), the application film 6 is attached, and the thermal adhesive mark portion 24 is peeled off from the support layer 3 (see FIGS. 2B and 2C). The heat-bonding mark portion 24 to which the application film 6 is attached is placed on the adherend 8 and the heat press board 1
After heat transfer by sandwiching it between 2, 12 ', the application film 6 is peeled off to form a heat-bonding mark 23 [see FIG. 2 (e)].

The shape of the back surface of the application film 6 (the surface in contact with the printing layer 5) is transferred to the surface of the heat-adhesive mark 23, and in many cases, it becomes mottled and the pattern of the printing layer 5 becomes unclear. is there.

Therefore, as shown in FIG. 4A, a predetermined amount is provided on the front surface (upper surface) of the heat-bonding mark 23 attached to the adherend 8 and on the back surface (surface facing the print layer 5 of the heat-bonding mark 23). The release sheet 10 on which gloss, matte or other design is formed is placed, sandwiched between the hot press plates 12 and 12 ', reheated to the softening temperature of the base material layer 1, pressurized, and then cooled. As shown in FIG. 4B, the release sheet 10 is peeled off, and the design of the release sheet 10 is transferred to the surface of the heat-bonding mark 23 to form a predetermined surface design 11. [Fig. 4 (c)]. The release sheet 10 may be a PET film, paper, or the like as long as it has a releasability from the base material layer 1 on the back surface (front surface design surface).

The temperature condition for reheating and pressurizing is preferably at least the softening temperature of the base material layer 1 and at most the softening temperature plus 60 ° C. “Resamine ME-44L with a softening temperature of 130 ° C. as the base material layer 1
P ”(product number, manufactured by Dainichiseika Kogyo Co., Ltd.) is heated at 120 ° C. and pressurized, the design of the release sheet 10 is not transferred to the base material layer 1 and heated at 190 ° C. Then, the pattern printed on the base material layer 1 flows, and the base material layer 1 is further pushed into the adherend 8 such as clothing, so that the hiding property is lost. When the heating temperature was set to 150 ° C. and 160 ° C., the design of the release sheet 10 was transferred to the base material layer 1 and the pattern did not flow.

As is apparent from the above description,
The thermal transfer print marking sheet of the present invention and the method for producing the same have the following effects.

In the thermal transfer print marking sheet according to claim 1, the adhesive force between the surface of the support layer and the adhesive layer for hot melt is 5 to 150 g / 25 mm, and thus the process for producing the thermal transfer print marking sheet. Makes cutting and application easier.
When this adhesive strength is less than 5 g / 25 mm, when cutting small characters or a sharp-angled portion of a printed pattern,
Wrinkling may occur due to peeling or rising between the support layer and the hot melt adhesive. If the adhesive strength exceeds 150 g / 25 mm, it becomes difficult to remove unnecessary portions or peel off the heat-adhesive mark portion to which the application film is attached from the support layer.

The thermal transfer print marking sheet according to claim 2 has a step of being wound into a coil before printing on the base material layer, and bringing the back surface of the support layer into contact with the base material layer. By making the adhesive force between the back surface of the support layer and the base material layer smaller than the adhesive force between the surface of the support layer and the adhesive layer for hot melt, the back surface of the support layer and the base layer can be used when developing in the next step. The material layer is designed to develop smoothly. When the adhesive force between the back surface of the support layer and the base material layer is large, blocking occurs when developing, or if it is forcibly developed, peeling occurs between the support layer and the adhesive layer for hot melt and the next step is performed. I can't send it.

In the thermal transfer print marking sheet with the surface protective layer according to claim 3, the adhesive force between the back surface of the surface protective layer and the base material layer is 1 g / 25 mm or more, so that the sheet is wound up and unwound in the laminating step. In such a step, the surface protective layer does not peel off from the base material layer to cause wrinkles or scratches. Further, since the adhesive force between the back surface of the support layer and the base material layer is smaller than the adhesive force between the surface of the support layer and the adhesive layer for hot melt, the surface protective layer is peeled off from the base material layer in the next step. In this case, the problem of peeling between the support layer and the hot melt adhesive does not occur.

In the thermal transfer print marking sheet having the surface protective layer according to the present invention, the surface design is formed on the surface of the surface protective layer to be laminated with the base material layer. When wound up as a print marking sheet, the surface design of the surface protective layer such as matting and glazing can be transferred to the base material layer to impart a unique effect to the next printing.

A method for producing a thermal transfer print marking sheet having a surface protective layer according to the fifth aspect of the present invention comprises producing a laminate A having two layers and a laminate B having two layers, followed by bonding for hot melt. By laminating the agent layer and the base material layer facing each other, only the two-layer laminated body is handled as the intermediate laminated body, and the three-layered intermediate laminated body is treated like the method of sequentially laminating these four layers. There is no need to handle, the stacking work is easy, and the stacking device is small.

In the method for producing the thermal transfer print marking sheet having the surface protective layer according to the sixth aspect, the method of laminating the laminate A and the laminate B is dry lamination,
Alternatively, it is heat lamination, and dry lamination or heat lamination can be selected depending on the stickiness of the hot melt adhesive. The process is simplified and a clean environment can be maintained.

In the method for producing the marking sheet with a surface protective layer according to claim 7, in the step of producing the laminate A, the adhesive force between the surface of the support layer and the hot melt adhesive layer is changed to the support layer. The adhesive force for hot melt adheres strongly to the back surface of the support layer when the laminated body A is rolled up and unfolded in the next step by making it stronger than the adhesive force between the back surface and the hot melt adhesive layer. It can be deployed smoothly without any problems.

In the method for producing the marking sheet with a surface protective layer according to claim 8, in the step of producing the laminate B, the adhesive force between the back surface of the surface protective layer and the base material layer is When the laminate B is rolled up in the next step after being wound up by increasing the adhesive strength with the base material layer,
The base material layer does not strongly adhere to the surface of the surface protective layer and can be smoothly spread.

The heat-bonding mark with surface design according to claim 9 is the surface of the heat-bonding mark obtained by printing a predetermined design on the base layer of the thermal transfer print marking sheet according to claim 1 and bonding it to an adherend. Then, a design sheet having releasability is superposed and reheated and pressed to add new effects such as matting and polishing to the surface of the thermal adhesive mark. By setting the temperature of this reheating to a predetermined range based on the softening temperature of the base material layer, the surface design of the design sheet is sufficiently transferred, and the design such as a pattern is deformed due to overheating, or the base fabric. It will not be pushed into and will not become thin.

As described above, the thermal transfer print marking sheet of the present invention enables clear full-color printing / cutting by a thermal transfer print / cutting machine, and peels off unnecessary parts (dust removal) and heat-bonds it to an adherend. The heat-bonding mark can be easily formed. Further, according to the manufacturing method of the present invention, even when the laminate is wound into a coil in the intermediate step, the sheet does not cause blocking or peeling and the sheet can be smoothly developed. Furthermore, a heat-bonding mark with a surface design has been proposed in which a new design is added to the surface of the heat-bonding mark.
