Description

The present invention relates to a method for manufacturing a transfer tape for transferring a favorite pattern onto the surface of various paper products such as greeting cards, wrapping paper, learning notes, and the like, and a method for manufacturing a transfer tool incorporating the transfer tape. It is.

In recent years, a transfer tape that has been printed in advance with patterns such as figures, symbols, and characters in advance, and has been given pressure-sensitive transfer properties so that the pattern can be transferred to a transfer surface such as the surface of the paper product. However, it is becoming popular as one of the so-called fancy stationery.
As such a transfer tape, for example, those described in Patent Documents 1 and 2 can be used.

That is, in the transfer tape described in Patent Document 1, a mark forming layer is formed on one side of a base material that has been subjected to a release treatment on both sides, and after a pattern is printed on the surface by an arbitrary printing method, pressure-sensitive adhesive is further applied. It is configured by stacking layers.
In addition, the transfer tape described in Patent Document 2 has a surface protective layer laminated directly on one side of a base material or in a state where a release treatment is performed, and a pattern is printed on the surface protective layer by any printing method. In addition, a pressure-sensitive adhesive layer is laminated thereon.

As printing methods for these transfer tapes, conventional printing methods such as gravure printing method, letterpress printing method, offset printing method, silk screen printing method, tampo printing method, pad printing method and the like are assumed. Further, as a printing method, for example, an electrostatic printing method, a thermal transfer printing method, an ink jet printing method, or the like can be adopted.
Although not a transfer tape, Patent Document 3 describes an image recording medium in which a pattern is printed on a thermoplastic resin film by a dry electrostatic printing method, and the configuration of the thermoplastic resin film of the image recording medium is transferred. It can also be applied to tape.

However, conventional general printing methods such as the gravure printing method require a predetermined original plate and are suitable for printing a large amount of detailed patterns. And there is a problem that it is not suitable for frequent picture changes.
On the other hand, according to the electrostatic printing method, the thermal transfer printing method, the ink jet printing method, etc. that can be directly printed (on-demand printing) based on the data produced in a computer without requiring an original plate, It is possible to respond.

However, in both the general printing method and the conventional printing method capable of on-demand printing, the younger generation who is the main user of such stationery has a narrow transfer tape, for example, a width of about 10 mm or less. It is difficult to finely print a fine pattern as desired with high resolution, and there is a problem that the pattern is blurred.
According to the wet electrostatic printing method using liquid toner, a very small pattern 6 corresponding to a narrow transfer tape having a width of about 10 mm or less is finer than that obtained by other conventional printing methods, for example, 600 dpi. It is possible to print by on-demand printing with an image quality exceeding.
However, when the transfer tape is incorporated in a transfer tool and transferred onto the transfer surface as will be described later, the pattern may extend in the transfer direction, and the pattern 6 having the same image quality as the original image may not be formed.
In particular, in the transfer tape of Patent Document 1, the mark forming layer exposed on the outermost surface after transfer is given adhesiveness for holding the adhesive to the base material. There is also a problem that the image can be easily removed from the transfer surface or the pattern is easily stained.

An object of the present invention is to provide a method for producing a transfer tape that can form a finer pattern than on-demand printing by on-demand printing, and that does not cause the pattern to be easily removed or stained even if it is rubbed with a fingertip after transfer. It is in.
It is another object of the present invention to provide a method for manufacturing a transfer tool that can easily transfer the design of the transfer tape to a transfer surface such as a paper product.

In the present invention, a release layer having a thickness of 0.5 μm or more and 5 μm or less made of a cellulose-based resin is formed on one side, and the opposite side is the one side of the base material that has been subjected to release treatment or release treatment by the release layer . , the exposed surface of the release layer comprises ethylene acrylic acid resin, laminating a fixing layer having a fixability of a picture which is formed by an electrostatic printing method of wet using liquid toner, exposure of the fixing layer The transfer tape manufacturing method includes a step of forming a pattern on the surface by the wet electrostatic printing method and a step of forming a pressure-sensitive adhesive layer on the fixing layer on which the pattern is formed.
The present invention also includes a step of winding the transfer tape manufactured by the manufacturing method of the present invention around a supply reel, and a fixing layer of the transfer tape fed out from the supply reel, based on the adhesive force of the pressure-sensitive adhesive layer. peeling while pressure sensitive head to transfer to the transferred surface of wood, the fixing layer takes up the substrate after the transfer take-up reel, and the transfer tool comprising a one hand grip usable device body that houses the respective parts A method of manufacturing a transfer tool including a step of incorporating the supply reel .

According to the present invention, it is possible to provide a method for producing a transfer tape that can form a finer pattern than on the current state by on-demand printing, and that can be easily removed or soiled even if it is rubbed with a fingertip after transfer.
Moreover, according to this invention, the manufacturing method of the transfer tool which can transcribe | transfer the pattern of the said transfer tape easily to to-be-transferred surfaces, such as paper products, can be provided.

Fig. (A) is an enlarged cross-sectional view showing a layer configuration of an example of an embodiment of a transfer tape manufactured by the manufacturing method of the present invention, and Fig. (B) shows a fixing layer of the transfer tape, a pressure-sensitive adhesive layer. It is sectional drawing which shows the state transferred to the to-be-transferred surface via. Figure (a) it is produced by the production method of the present invention, cross-sectional view showing the internal structure of an example of rolling Utsushigu incorporating the transfer tape, (b) shows a side view of the transfer tool.

<Transfer tape>
FIG. 1A is an enlarged cross-sectional view showing a layer structure of an example of an embodiment of a transfer tape manufactured by the manufacturing method of the present invention, and FIG. 1B is a pressure-sensitive adhesive for the fixing layer of the transfer tape. It is sectional drawing which shows the state transferred to the to-be-transferred surface via the layer.
Referring to FIG. 1 (a), a transfer tape 1 of this example includes a film-like base material 2, and one side (lower side in the figure) of the base material 2 is a release layer 3 that can be peeled off from the one side. The opposite surface 4 (the upper surface in the figure) is subjected to a release treatment.

On the exposed surface (lower surface in the figure) of the release layer 3, a fixing layer 5 having a pattern fixability formed by a wet electrostatic printing method using liquid toner is formed, and the fixing layer 5 is exposed. After the pattern 6 is formed on the surface (the lower surface in the figure) by the wet electrostatic printing method, the pressure-sensitive adhesive layer 7 is laminated on the surface.
Then, the set of the release layer 3, the fixing layer 5, the pattern 6 on the fixing layer 5, and the pressure-sensitive adhesive layer 7 constitutes a transfer layer 9 that is peeled off from one side of the substrate 2 and transferred to the transfer surface 8. Yes.

1 (a) and 1 (b), the pressure-sensitive adhesive layer 7 of the transfer tape 1 is transferred from the opposite surface 4 side of the substrate 2 in contact with the transfer surface 8 such as a paper product. When the substrate 2 is peeled off while pressing toward the surface 8 side, the transfer layer 9 is transferred to the transfer surface 8.
That is, the fixing layer 5 peeled from the substrate 2 is adhesively fixed to the transfer surface 8 such as a paper product by the adhesive force of the pressure sensitive adhesive layer 7 together with the release layer 3, and the fixing layer 5 is fixed to the transfer surface 8. The pattern 6 formed in the above is transferred. The transferred pattern 6 is protected by the fixing layer 5 and the release layer 3 thereon.

(Substrate 2)
Among the above, examples of the substrate 2 include a resin film such as polysulfone, polystyrene, polyamide, polyimide, polycarbonate, polypropylene, polyethylene, polyester, and acetate, thin paper such as condenser paper and glassine paper, or cellophane.

Among them, a resin film is preferable in consideration of the fact that it can be made as thin as possible so that it can be incorporated into a transfer tool while being wound in a roll shape, and it is not easily cut by increasing toughness when thinned. .
(Peeling layer 3)
The release layer 3 is required to have the following functions.
(1) It has an easy releasability that can be easily peeled off from the substrate 2 when the pressure-sensitive adhesive layer 7 has an adhesive force with respect to the transfer surface 8.
(2) The fixing layer 5 and the pressure-sensitive adhesive layer 7 are transferred to the transfer surface 8 by the adhesive force.
Can be fixed to one side of the substrate 2. In particular, when the transfer tape 1 wound around the supply reel is fed out, the transfer layer 9 is carelessly peeled off from one side of the substrate 2 or transferred to the opposite side 4 due to the adhesive force of the pressure-sensitive adhesive layer 7. to prevent, tight adhesion force of the release layer 3 to one surface of the substrate 2 is larger than the adhesive strength of the pressure-sensitive adhesive layer 7 on the opposite surface 4 in which the release treatment of the substrate 2.
(3) It should have light transparency so that the pattern 6 can be visually recognized through the release layer 3 and the fixing layer 5 after being transferred to the transfer surface 8.
(4) Since it itself does not have adhesiveness and functions as a protective layer for the fixing layer 5, even if it is rubbed with a fingertip after transfer, the pattern 6 can be easily removed from the transfer surface 8 or soiled. What can be prevented.

In the present invention, in order to satisfy these functions , the release layer 3 is formed of a cellulose resin .

As the cellulose resin, for example, one or more of cellulose acetate butyrate resin, nitrocellulose resin, ethyl cellulose resin, methyl cellulose resin and the like are preferable.
When the release layer 3 is formed of a cellulose-based resin, the release layer 3 and by extension, the transfer layer 9 are cut off during transfer, and the pattern 6 extends in the same direction due to the tensile force applied in the length direction of the transfer layer 9 during transfer. And the fineness can be improved while maintaining a good pattern after transfer. Further, the transferability of the transfer layer 9 can be improved.

Note that a small amount of silicone may be added to the cellulose resin forming the release layer 3 in order to finely adjust the easy peelability to the substrate.
The thickness of the release layer 3 is 0.5μm or more, must be 5μm or less, is not preferable in particular 1μm or more.
When the thickness of the release layer 3 is less than this range, when the transfer tape 1 is manufactured, the release layer 3 is formed, and the pressure-sensitive adhesive layer 7 is applied after the fixing layer 5 is laminated. At this time, the pressure-sensitive adhesive penetrates to the inside, and the release layer 3 becomes sticky, which may reduce easy peelability during transfer.

Further, when the adhesiveness is generated, the function as a protective layer is lowered, and there is a possibility that the pattern 6 is easily removed or soiled when it is rubbed with a fingertip or the like after being transferred to the transfer surface 8.
On the other hand, when the thickness of the release layer 3 exceeds the above range, the adhesion to the substrate 2 is insufficient, and the release layer 3 is easily peeled off from one side of the substrate 2. For this reason, coupled with the fact that the film property of the entire transfer layer 9 becomes too strong, the transfer layer 9 is cut off at the time of transfer, and the transfer layer 9 after the transfer end position is excessively transferred. There is a risk of excessive peeling.

Further, when the transfer tape 1 is wound around the supply reel or when the transfer tape 1 is unwound from the wound state, so-called blocking may occur that the release layer 3 transfers to the opposite surface of the substrate 2.
Further, the transparency of the release layer 3 is lowered, and the pattern 6 may be blurred when viewed through the release layer 3 and the fixing layer 5.
(Release processing)
In order to release the opposite surface 4 of the substrate 2, for example, the opposite surface 4 is subjected to a treatment such as fluorination or chlorination, or a release agent containing a silicone resin, a fluorine resin, or the like is applied. do it.

(Fixing layer 5)
The fixing layer 5 is required to have the following functions.
(1) having a fixing of the pattern formed by the electrostatic printing method of wet using liquids toner, that is, the toner particles and the charging property of the liquid toner used in the wet electrostatic printing method is adapted, developed The toner particles are smoothly electrostatically attached in the process.
(2) that the toner particles are favorably fixed in a later fixing step has a high affinity for the upper Symbol toner particles.
(3) also have optical transparency can be visually recognized pattern 6 through the constant adhesive layer 5 after transferred to the transferred surface 8 with the fixing layer 5 and the release layer 3 thereon.

(4) a constant adhesive layer 5, in order to improve the turn off at the time of transfer of the transfer layer 9, it is a thermoplastic resin.
In the present invention, particularly when the toner particles in the liquid toner include those containing at least one binder resin selected from the group consisting of a vinyl acetate copolymer, an acrylic resin, and a polyester resin, In order to satisfy the conditions , the fixing layer 5 is a layer containing an ethylene acrylic resin.

The ethylene acrylic acid resin is, for example, a copolymer containing at least ethylene and acrylic acid as components, and the acrylic acid content is adjusted to about 8% by mass or more and 18% by mass or less by saponification or the like. An acid copolymer is mentioned.
Further, for example, a filler such as silica or talc, or an additive such as aluminum sulfate or carboxymethylcellulose may be added to the fixing layer 5 at an arbitrary ratio.

The thickness of the fixing layer 5 is 0.01 μm or more, particularly 0.05 μm or more, preferably 5 μm or less, and particularly preferably 1 μm or less.
If the thickness of the fixing layer 5 is less than this range, the fixability of the pattern 6 may not be sufficiently improved.
On the other hand, when the thickness of the fixing layer 5 exceeds the above range, the pattern 6 can be easily removed when it is rubbed with a fingertip or the like after being transferred to the transfer surface 8, or the transfer layer 9 is less cut when transferred. May cause the above-described excess peeling.

Further, the transparency of the fixing layer 5 is lowered, and the pattern 6 may be blurred when viewed through the fixing layer 5 and the release layer 3 thereon.
(Form 6)
On the exposed surface (lower surface in the figure) of the fixing layer 5, in the present invention, the pattern 6 is printed by a wet electrostatic printing method using liquid toner. Then, it is possible to print a very small pattern 6 corresponding to the transfer tape with a width as narrow as about 10 mm or less by on-demand printing with a finer resolution than that by other conventional printing methods.

That is, on-demand printing is difficult with a general printing method using an original plate such as a gravure printing method, as described above, and due to the accuracy of the original plate, the smaller the pattern itself, the lower the sharpness and the more easily the image becomes blurred. In particular, it is difficult to finely print the above-described minute pattern.
In addition, the ink-jet printing method that enables on-demand printing wets and spreads ink droplets that reach the surface to be printed, so the printing accuracy is limited to about 500 dpi. It just makes it look more detailed. For this reason, it is difficult to print the minute picture described above with high precision.

Also, the dry electrostatic printing method has a large particle size of toner particles, and the thermal transfer printing method limits the resolution to the number of elements of the thermal head. In both cases, the sharpness decreases as the pattern itself decreases. It becomes difficult to blur, and it is difficult to print minute pictures finely.
On the other hand, according to the wet electrostatic printing method using liquid toner, of course, on-demand printing is possible, and fine color development is possible with, for example, up to seven liquid toners.

In addition, since the toner particles in the liquid toner are significantly smaller in particle size than those used in the dry electrostatic printing method, the printing accuracy can be refined to a range exceeding 1000 dpi, for example, and the width is about 10 mm as described above. It is possible to print a very small pattern 6 corresponding to a narrow transfer tape such as the following more finely than that obtained by other conventional printing methods.
(Pressure-sensitive adhesive layer 7)
Examples of the pressure-sensitive adhesive that forms the pressure-sensitive adhesive layer 7 include acrylic emulsion, natural rubber, styrene-butadiene copolymer, butadiene copolymer, acrylate copolymer, vinyl ether copolymer, and ethylene vinyl alcohol. Can be mentioned.

In particular, considering the suppression of permeation into the fixing layer 5 and the release layer 3 as the base, and maintaining the good characteristics of each of these layers or suppressing blocking, the pressure-sensitive adhesive is, among the above, A water-based pressure-sensitive adhesive is preferable, and an acrylic emulsion is particularly preferable.
The thickness of the pressure-sensitive adhesive layer 7 is preferably 0.5 μm or more, particularly 2 μm or more, and preferably 10 μm or less, particularly 5 μm or less.

If the thickness of the pressure-sensitive adhesive layer 7 is less than this range, good pressure-sensitive adhesiveness cannot be imparted and transfer failure may occur. On the other hand, when the thickness of the pressure-sensitive adhesive layer 7 exceeds the above range, the pressure-sensitive adhesiveness becomes too strong, and blocking may occur.
<Transfer tool>
Figure 2 Figure (a) is produced by the production method of the present invention, cross-section showing the internal structure of an example of incorporating rolling Utsushigu the transfer tape, and FIG. 2 (b) is a side view of the transfer tool .

  Referring to FIGS. 1A, 1B and 2A, 2B, the transfer tool T of this example is a supply reel 11 in which the transfer tape 1 is wound with the pressure-sensitive adhesive layer 7 side outside. A pressure-sensitive head 12 for transferring the fixing layer 5 of the transfer tape 1 fed from the supply reel 11 together with the release layer 3 to the transfer surface 8 while being peeled from the substrate 2 by the adhesive force of the pressure-sensitive adhesive layer 7; And a take-up reel 13 for taking up the substrate 2 after transfer through a roller R or a pin.

Among the above, the supply reel 11, the roller R or the pin, and the take-up reel 13 are accommodated in a container 10 that can be gripped and used with one hand.
The vessel body 10 is formed by combining halves 10a and 10b made of front and rear plastic moldings. Further, the container body 10 is formed with a recess 50 so as to facilitate pressurization during transfer by pressing with a finger when grasped with one hand.

In addition, the pressure-sensitive head 12 is exposed to the outside of the body 10 so that the lower side becomes the pressure-sensitive transfer portion 12b and the upper side becomes the return path portion 12c of the base material 2 with the tip 12a as a boundary, and the support portion 12d is A shaft 14 is elastically supported within the body 10.
Reference numeral 40 denotes an elastic plate provided in the course of the passage of the transfer tape 1 between the shaft support 14 and the supply reel 11 and the pressure-sensitive head 12, and is applied to the substrate 2 side of the transfer tape 1. By touching the transfer tape 1, a good tension state can be maintained. In the illustrated case, the elastic plate 40 is integrally formed from the support portion 12d of the pressure-sensitive head 12, but a separate member may be used.

The gear G1 on the supply reel 11 side and the gear G2 on the take-up reel 13 side are meshed so that the supply reel 11 and the take-up reel 13 rotate in opposite directions in conjunction with each other.
Although not shown, the supply reel 11 is provided with a brake mechanism, a ratchet mechanism, and the like for rotating the supply reel 11 only in the feeding direction of the transfer tape 1.
In order to transfer the pattern 6 of the transfer tape 1 to the transfer surface 8 using the transfer tool T of this example having the above-described parts, first, the pressure-sensitive adhesive layer 7 of the transfer tape 1 is formed by the pressure-sensitive head 12. 2 (a) and 2 (b) in pressure contact with the transfer surface 8, the entire transfer tool T is moved in the direction indicated by the white arrow in the figure.

  Then, the transfer tape 1 on the supply reel 11 side from the pressure contact position is sequentially fed out from the supply reel 11 by the adhesive force of the pressure-sensitive adhesive layer 7 and the movement, and the fixing layer 5 of the fed transfer tape 1 is peeled off. The layer 3 is adhesively fixed to the transfer surface 8 while being sequentially peeled from the substrate 2 by the adhesive force of the pressure sensitive adhesive layer 7, and the pattern 6 formed on the fixing layer 5 is transferred to the transfer surface 8. .

Further, the rotation of the supply reel 11 accompanying the feeding of the transfer tape 1 is transmitted to the take-up reel 13 through the gears G 1 and G 2, and the take-up reel 13 is rotated so that the substrate 2 after transfer is transferred to the take-up reel 13. It is wound up.
After transferring the pattern 6 having a predetermined length, the pressure-sensitive head 12 is separated from the transfer surface 8. Then, the set of the release layer 3, the fixing layer 5, the pattern 6 and the pressure-sensitive adhesive layer 7 transferred to the transfer surface 8, that is, the transfer layer 9 is separated from the untransferred portion, and the transfer is completed.

Note that the configuration of the present invention is not limited to the embodiment described above.
For example, in the transfer tape 1, not only the opposite surface 4 of the substrate 2 but also one surface side may be subjected to mold release treatment and the release layer 3 may be omitted. In that case, there is an advantage that the productivity of the transfer tape 1 can be improved by reducing the number of layers.
However, since the release layer 3 can also function as a protective layer for the fixing layer 5 and the picture 6, one side of the substrate 2 is formed by the release layer 3 in order to ensure the function as the protective layer as shown in the figure. In order to perform the peeling treatment and still reduce the number of layers as much as possible, the opposite surface 4 is preferably subjected to a release treatment.

If the transfer tool T includes the supply reel 11 around which the transfer tape 1 is wound, the pressure-sensitive head 12, the take-up reel 13, and the container 10, other configurations can be changed as appropriate.
In addition, arbitrary design changes can be made without departing from the configuration of the present invention.

<Example 1>
As the substrate 2, a polyester film having a thickness of 25 μm obtained by releasing the opposite surface 4 is used, and a coating solution for the release layer 3 containing a cellulose resin [Washin coat (Washin Chemical Industry Co., Ltd. (Registered trademark) TF-1220] was applied and dried to form a release layer 3 having a thickness of 1 μm.

In addition, 2.5 parts by mass (solid content) of ethylene acrylic resin [AD-37F1 manufactured by Toyo Morton Co., Ltd.] and 2.5 parts by mass (solid content) of colloidal silica [Cavos Perth II manufactured by Cabot Corporation] Further, ion exchange water was added to prepare a coating solution having a total solid content of 5% by mass.
The coating solution was applied onto the release layer 3 and dried to form a fixing layer 5 having a thickness of 0.5 μm.

Next, after the pattern 6 is formed on the exposed surface of the fixing layer 5 by a wet electrostatic printing method using liquid toner, an acrylic emulsion as a water-based adhesive (S9059 manufactured by Asahi Kasei Co., Ltd.) is formed thereon. Was applied and dried to form a pressure sensitive adhesive layer 7 having a thickness of 3 μm, and further slit to a width of 5 mm to produce a transfer tape 1.
Then, the manufactured transfer tape 1 was wound around the supply reel 11 with the pressure-sensitive adhesive layer 7 facing outside, and incorporated in the transfer tool T shown in FIG.

<Comparative Example 8 >
Instead of the fixing layer 5, a print layer having a thickness of 5 μm containing polyvinyl chloride resin (PVC) and having a printability of gravure ink is formed, and a pattern 6 is formed on the exposed surface of the print layer by a gravure printing method. Except for the above, the transfer tape 1 was manufactured in the same manner as in Example 1 and incorporated in the transfer tool T.

<Evaluation of fineness of pattern>
In each of the examples and comparative examples, the pattern 6 is formed by the respective printing method based on the original image exceeding the resolution of 600 dpi, and the transfer tape 1 is manufactured and incorporated in the transfer tool T, and then the transfer tool T is used. The pattern 6 was transferred to the transfer surface 8 and observed with a microscope.

There was a sticky feeling, and everything was removed after 10 rubs. Bad.
The above results are shown in Tables 1 to 3.

From the results of Examples 1 to 3 and Comparative Examples 6 to 8 in Tables 1 to 3 , by adopting a wet electrostatic printing method as a printing method, it was excellent in definition compared to other conventional printing methods. It was found that the pattern 6 can be formed.
However, from the results of Examples 1 to 3 and Comparative Example 5 , for that purpose, a fixing layer 5 having a fixability of a pattern formed by a wet electrostatic printing method is provided, and the pattern 6 is formed on the fixing layer 5. I found it necessary.

In addition, from the results of Example 1 and Comparative Example 1 , it is possible to use a substrate 2 having a release treatment only on the opposite surface 4 and forming a release layer 3 on one side, and using the release layer 3 as a protective layer.
