Description

The present invention relates to a pressure-sensitive transfer adhesive tape in which an adhesive portion is transferred to a transfer target by being pressed against the transfer target by a hand-held transfer tool, and a transfer tool including the transfer adhesive tape.

There is a pressure-sensitive transfer pressure-sensitive adhesive tape in which an adhesive portion is transferred to a transfer target by being pressed against the transfer target by a hand-held transfer tool.
Unlike a liquid paste or a solid paste, such a transfer adhesive tape can easily transfer an adhesive portion to a transfer target without soiling a hand, and does not require a drying time until bonding and is a transfer target. There is an advantage that, for example, paper or the like does not wrinkle.

However, when such a transfer adhesive tape is mounted on a transfer tool and transferred to a transfer target, when the transfer tool is finished and the transfer tool is pulled up from the transfer target, the adhesiveness of the transfer adhesive tape is not sharp ( , Which is referred to as “glue resistance”), and a phenomenon occurs in which a thread is pulled between the adhesive portion transferred to the transfer target and the adhesive portion on the transfer tool side, which may hinder the transfer operation. ..

Therefore, in order to improve the adhesiveness of the adhesive portion of the transfer adhesive tape, there is one in which the adhesive portion has, for example, an island-shaped discontinuous pattern shape (see, for example, Patent Documents 1 and 2).

However, when the adhesive portion is discontinuous, the area ratio of the adhesive portion on the base material decreases, and the adhesive strength of the transfer adhesive tape decreases.
Furthermore, when the transfer adhesive tape is transferred to a transfer target under a low temperature environment or a high speed condition, a part of the discontinuous adhesive part is not peeled from the base material and remains on the base material (hereinafter, referred to as “unreleased”). It is apt to occur.
Further, since the transfer adhesive tape is in a roll state, the adhesive portion is in contact with the peeling layer on the back side of the base material on the inner side of the circumference. Since the transfer adhesive tape also has an adhesive portion on the surface of the release layer of the base material, unlike a general adhesive tape that does not have releasability on the adhesive portion side of the base material, the transfer adhesive tape can be transferred at high speed from a roll state. When is unrolled, the pressure-sensitive adhesive may migrate (hereinafter referred to as “blocking”) to the back side peeling layer. In particular, when the adhesive portion has a discontinuous pattern shape, blocking is likely to occur.

Next, the results of comparing the following performances of the transfer adhesive tapes 1 of Examples 1-5 and Comparative Examples 1-4 will be described.

<Evaluation of adhesiveness>
The transfer adhesive tape 1 in the form of a pancake is loaded into a transfer tool 10 (PN-MS, manufactured by Tombow Pencil Co., Ltd.), and the adhesive part 1 is transferred to PPC (plane paper copy) paper, and then the transfer tool 10 is vertically moved.

The transfer property of the adhesive portion 11 was observed by running on PPC paper at a speed of 2 seconds. And it evaluated as follows.
⊚: Transferred at a speed of 30 cm/sec without chipping or omission due to non-peeling of the adhesive part 11 ◯: Transferred without chipping or omission due to unpeeling of the adhesive part 11 at a speed of 20 cm/sec Δ: Transfer is performed at a speed of 10 cm/sec without peeling or missing due to non-peeling of the adhesive portion 11. ×: At a speed of 10 cm/sec, a portion of the adhesive portion 11 is missing or missing due to unpeeling.

<Evaluation of adhesive strength>
The transfer adhesive tape 1 in the form of a pancake was loaded into a transfer tool 10 (PN-MS manufactured by Tombow Pencil Co., Ltd.), transferred to a commercially available paper envelope (trade name: ASKUL craft envelope), sealed, and sealed at 1 Kg. The roller of 1 was reciprocated once for pressure bonding. This was opened after a lapse of a predetermined time, and the states of the adhesive portion 11 and the paper piece (the portion to which the adhesive tape was transferred) were evaluated as follows.
◯: The adhesive portion 11 destroys the entire surface of the paper piece and peels off Δ: The adhesive portion 11 destroys a part of the paper piece and peels off ×: Peels off at the interface between the adhesive portion 11 and the paper piece

(Performance comparison)
FIG. 12 shows the above performance evaluation comparison results for the transfer adhesive tapes 1 of Example 1-5 and Comparative example 1-4 described above. FIG. 12 shows the examples and the comparative examples arranged in order from the lowest ratio of the adhesive portion. The mark (◯) (x) above the pattern shape in FIG. 12 indicates that the non-adhesive portion is discontinuous (◯) and the non-adhesive portion is not discontinuous (×).

(1) Area Ratio of Adhesive Portion As described above, in the transfer adhesive tape 1 of the embodiment, the area ratio of the adhesive portion 11 to the entire area of the transfer surface is 35% to 80%, and 40% to 80%. It is preferably from 50% to 80%, more preferably from 50% to 80%.
In order to determine only the influence of the area ratio of the adhesive portion 11, Comparative Example 3, Example 4, and Comparative Example 2 are compared. The shapes of the adhesive portion 11 and the non-adhesive portion 12 are substantially the same, and only the area ratio of the adhesive portion 11 is different. In Comparative Example 3 and Comparative Example 2, the ratio of the adhesive portion 11 is outside the range of the embodiment. ..
As shown in Comparative Example 3, it can be seen that when the ratio of the adhesive portion 11 is 30.7%, which is smaller than the range of the embodiment, the adhesive force becomes weak.
As shown in Comparative Example 2, it can be seen that when the ratio of the adhesive portion 11 is 86.6%, which is higher than the range of the embodiment, the adhesiveness deteriorates.
On the other hand, as shown in Example 4, when the ratio of the adhesive portion 11 is 57.6% which is the range of the embodiment, both the adhesive force and the adhesiveness are good.

(2) Discontinuity of Non-Adhesive Portion 12 Next, in order to evaluate the difference in performance of the transfer adhesive tape 1 depending on whether or not the non-adhesive portion 12 is discontinuous, Example 3, Comparative Example 1, and Implementation Example 4, Example 2, and Example 1 are compared. In all of these, the shape of the main adhesive portion 111 is circular. Further, the area ratio of the adhesive portion 11 to the entire area of the transfer surface was 54.8% in Example 3, 57.1% in Comparative Example 1, 57.6% in Example 4, and 58.% in Example 2. 5%, 77.0% in Example 1, and in all cases, the area ratio of the adhesive portion 11 to the entire area of the transfer surface is 35% to 80% of the embodiment.
However, in any of Examples 4, 2, and 1, the non-adhesive part 12 is separated by the connecting adhesive part 112, and the transfer adhesive tape 1 is cut from one end in the lateral direction or the other end in the longitudinal direction. Although it is discontinuous at the other end, Comparative Example 1 does not have a connecting adhesive portion, and the non-adhesive portion 12 is from one end in the lateral direction of the transfer adhesive tape 1 to the other end and from one end in the longitudinal direction to the other end. It is continuous.

When the non-adhesive portion 12 is continuous as in Comparative Example 1, the transferability and the adhesive force are higher than those of the non-adhesive portion 12 of Example 3, Example 4, Example 2, and Example 1 which are non-continuous. It can be seen that both of these are inferior in anti-blocking property and blocking resistance.

Even if the shape of the main adhesive portion 111 is not circular, comparing Example 5 in which the non-adhesive portion 12 is discontinuous with Comparative Example 4 in which the non-adhesive portion 12 is continuous, the results of Comparative Example 4 are as follows. Although the ratio of the adhesive portion is 55.6%, which is higher than 50.8% of Example 5, Comparative Example 4 is inferior to Example 5 in transferability, blocking resistance and adhesive strength.

The reason why the discontinuity of the non-adhesive portion 12 affects the performance improvement of the transfer adhesive tape 1 can be considered as follows.
When the non-adhesive portions 12 are continuous, the adhesive portions 11 are independent of each other. Then, depending on the adhesive force of each adhesive portion 11 and the surface state of the transfer target body, even if the adhesive portion 11 comes into contact with the transfer target body, the adhesive portion 11 is not transferred to the transfer target body and the transfer surface of the base material is not transferred. Is likely to remain (that is, unpeeling occurs).
Further, even when the wound transfer adhesive tape 1 is unrolled, the adhesive portion 11 is moved to the inside by the adhesive force of each adhesive portion 11 and the surface state of the peeling layer on the back side of the base material 2 on the inside of the circumference. There is a high possibility that it will be transferred to the release layer.
In addition, regarding adhesive strength (paper destructiveness), if the adhesive parts are independent, when peeling a piece of paper, even if the paper breaks at each individual adhesive part, there is no adhesive part (non-adhesive). It is easy to break at the part where the adhesive part is continuous), so it is difficult to destroy the entire surface of the paper piece.
Therefore, it is considered that in Comparative Example 4 and Comparative Example 1 in which the non-adhesive portions 12 are continuous, the transferability, the adhesive force, and the blocking resistance are inferior to those in the Examples.

On the other hand, when the non-adhesive portion 12 is discontinuous, the main adhesive portion 111 is continuous by the connecting adhesive portion 112.
Then, even if the adhesive force of the specific adhesive portion is weak or the surface state of the transfer destination of the transfer target is a portion in which transfer is difficult, the peripheral adhesive portion 11 is transferred to the transfer target. Then, the specific adhesive portion 11 is pulled toward the transfer target by the connecting adhesive portion 112 extending from the transferred adhesive portion 11. As a result, unpeeling is less likely to occur and transferability is improved.
Further, even when the wound transfer adhesive tape 1 is unrolled, the adhesive force is high in a specific adhesive portion, or the surface state of the back side of the substrate 2 on the inner side of the circumference is a state in which the adhesive portion is easily transferred. Even if it is a portion (in the state of insufficient peelability), the specific adhesive portion 11 is pulled toward the adhesive portion side release layer side by the connecting adhesive portion 112 extending from the adhesive portion 11 on the adhesive portion side release layer. To be As a result, the phenomenon in which the adhesive portion 11 is transferred to the peeling layer on the back side is unlikely to occur, and thus the blocking resistance is also improved.
Further, regarding the adhesive force (paper destructiveness), if the main adhesive portion 111 is continuous by the connecting adhesive portion 112, the paper is easily broken without interruption when the paper pieces are peeled off. improves.
In particular, in the first embodiment, the plurality of connecting adhesive portions 112 are provided, and the plurality of connecting adhesive portions 112 include one main adhesive portion 111 and all the main adhesive portions 1112 surrounding the one main adhesive portion 1112. They are connected one-on-one. Due to such a relationship, transferability and blocking resistance are further improved.

As described above, according to the embodiment,
(1) The transfer adhesive tape 1 has an adhesive portion 11 and a non-adhesive portion 12 on the surface (transfer surface) of the base material 2 on which the adhesive portion 11 is applied.
(2) The area ratio of the adhesive portion 11 to the entire area of the transfer surface is 35% to 80%.
Further, the non-adhesive portion 12 is separated by the connecting adhesive portion 112 and is discontinuous from one end in the lateral direction of the transfer adhesive tape 1 to the other end and from one end in the longitudinal direction to the other end.
Therefore, it has good adhesive strength, good adhesiveness, transferability, and blocking resistance.

Even when the transfer pressure-sensitive adhesive tape 1 is transferred under a low temperature environment or a high speed condition, a part of the discontinuous pressure-sensitive adhesive portion 11 is not peeled from the peeling base material and an unpeeled portion of the pressure-sensitive adhesive portion 11 is unlikely to occur. Further, when slitting is performed at high speed, blocking of the peeling layer on the back surface side of the adhesive portion 11 is unlikely to occur. Therefore, the manufacturing speed is improved.

(3) In the adhesive section 11, the main adhesive section 111 and the connecting adhesive section 112 that connects one main adhesive section 111 to another main adhesive section 111 are formed in a predetermined pattern. Since it is formed in a predetermined pattern in this way, it is easy to manufacture.

(4) The thickness of the connecting adhesive portion 112 is smaller than the thickness of the main adhesive portion 111.
Since the connecting adhesive portion 112 is thinner than the main adhesive portion 111, if the thickness is the same, the aspect ratio of the concave portion for forming the connecting adhesive portion 112 in the gravure coater becomes high, and the adhesive portion forming coating reaches the inside of the concave portion. It becomes difficult for the liquid to enter, and it becomes difficult to manufacture the uniform connected adhesive portion 112.
Further, when the recess has a high aspect ratio, it is difficult to be transferred even when it is transferred to the base material 2, so that it may be transferred unevenly, or a cut portion may occur in the connection adhesive portion 112.
However, according to the embodiment, since the thickness of the connecting adhesive portion 112 is thinner than that of the main adhesive portion 111, such a problem is unlikely to occur.

(5) In the lateral direction of the transfer pressure-sensitive adhesive tape 1, a row composed of a plurality of main pressure-sensitive adhesive portions 111 arranged at regular intervals is provided at regular intervals in the longitudinal direction. Since the main adhesive portions 111 are arranged in the lateral direction in this manner, the adhesive portions 11 are easily cut along the lateral direction when the adhesive is cut, the adhesive property is good, and the adhesive portion 11 is cut at a predetermined position during transfer. it can.
In addition, between the main adhesive portions 111 in one row, the main adhesive portions 111 in the rows located before and after in the longitudinal direction with respect to the row are arranged. Therefore, the main adhesive portions 111 can be arranged uniformly and efficiently.

(6) When the connecting adhesive portion 112 is parallel to the lateral direction, when the excess portion is scraped off by the blade in the gravure coater, the portion that becomes the connecting adhesive portion 112 may be scraped off. Furthermore, when the connecting adhesive portion 112 is provided so as to extend obliquely with respect to the short-side direction as in the third and third embodiments, the possibility of being scraped off by the blade is reduced, and the connecting adhesive portion 112 is more reliably removed. It can be manufactured.
