In this tape, the adhesive is not present in the concave portions and the adhesive is present only in the convex portions, so unnecessary adhesive force can be reduced. JP-A-1-204986 describes an easy-to-stick anticorrosion film having a similar structure. This film promotes the flow of air at the time of sticking and can be stuck without causing an air pocket. . This tape is manufactured by applying an adhesive to a substrate and then pressing it with a mold having an uneven pattern.

る精密なパターン形成は非常に困難であった。Japanese Unexamined Patent Publication (Kokai) No. 3-167281 discloses a method of providing a pressure-sensitive adhesive layer having a fine-pitch striped pattern on a support, and after applying the pressure-sensitive adhesive to the surface of the support, it has a fine striped pitch. A method using a comb-shaped scraping blade is described. As a method for forming the uneven pattern of the pressure-sensitive adhesive layer on the support, in pattern formation by gravure printing, screen printing, etc., at the time of pattern coating, stringing of the pressure-sensitive adhesive (when the coating liquid has high viscosity) or coating The liquid flows and the pattern is deformed (when the coating liquid has low viscosity)
Therefore, it was very difficult to form a precise pattern on the thin adhesive layer.

不可能であった。In the method of applying "pressing with a mold having a concavo-convex pattern" after applying the adhesive layer, it is difficult to press the adhesive layer having a thin dry thickness, and it is very difficult to form a precise pattern. there were. The method using a comb-teeth-shaped scraping blade having a fine striped pitch cannot form an uneven pattern such as letters and numbers or a striped pattern not parallel to the coating direction. In addition, in order to form a fine pattern, it is necessary to scrape off the applied adhesive coating liquid in a state where it does not dry, so the coating liquid will flow after the scraping and the pattern will be deformed. A striped pattern (pitch less than 1000 μm) could not be formed.

くなり、発明の効果が充分発揮されない。When the adhesive layer is thick and the uneven pattern is rough (large pitch and amplitude), when it is applied as an adhesive tape, the surface opposite to the applied side becomes uneven. Further, if a thick film is used so that the uneven pattern of the adhesive layer does not appear on the opposite side of the film, the adhesive tape becomes bulky when it is stored and the attached tape itself becomes thick. Also, when the adhesive layer is unnecessarily thick, the adhesive tape naturally becomes thick in the same manner. If a precise concavo-convex pattern cannot be formed, it becomes difficult to identify characters, numbers, figures, symbols, etc., and the effects of the invention will not be sufficiently exerted.

連続している必要がある。Further, when the pressure-sensitive adhesive layer has a block-like discontinuous concave-convex pattern, the pressure-sensitive adhesive layer is easily detached. Particularly, when the thickness of the adhesive layer becomes thin, this detachment becomes remarkable, and therefore the adhesive layer needs to be continuous within the range where the effect of the present invention is not lost.

１０〜９０％であるのが好ましい。The pressure-sensitive adhesive layer has an uneven shape with a pitch of 1 mm or less. If this pitch is larger than 1 mm, it becomes difficult to draw precise characters, numbers, figures, symbols and the like. In the concave-convex shape of the pressure-sensitive adhesive, the height of the convex portion from the surface of the support is preferably 20 μm or less. This height is 2
If it exceeds 0 μm, it becomes difficult to form a precise uneven shape. The height of the concave portion from the surface of the support is preferably 10 to 90% of the height of the convex portion.

Further, when it is more than 90%, the concave portions are also adhered and the effect of the unevenness cannot be exerted, so that the control of the adhesive force, the manifestation of anisotropy depending on the peeling direction of the adhesive force, the identification of characters, mathematics, symbols, etc. It will be difficult. The concavo-convex shape of the pressure-sensitive adhesive layer is arranged substantially parallel to each other, and the shape of the cross section in the direction perpendicular thereto is substantially wavy.

接触し、他方ロール表面の凹部は接触しない。In the production of the pressure-sensitive adhesive tape of the present invention, first, a pressure-sensitive adhesive containing a volatile solvent is prepared, and the pressure-sensitive adhesive is made to have a predetermined thickness by conventional methods, for example, gravure coating, knife coating, extrusion. It is applied to the support by coating or the like. next,
While the applied pressure sensitive adhesive has fluidity, a roll having an uneven pattern is brought into contact with the surface of the support opposite to the surface coated with the pressure sensitive adhesive. As a result, the convex portion of the roll surface contacts the surface of the support opposite to the surface coated with the pressure-sensitive adhesive, while the concave portion of the roll surface does not contact.

This allows
A difference in surface tension occurs between a portion corresponding to the convex portion and a portion corresponding to the concave portion of the inner roll of the pressure-sensitive adhesive layer on the support, and migration of the pressure-sensitive adhesive component occurs. As a result, the portion of the pressure-sensitive adhesive layer corresponding to the concave portion of the roll becomes concave, and the portion corresponding to the convex portion of the roll becomes convex.

％の範囲であればよい。In order to form the uneven shape by the above method, it is preferable to heat the temperature of the roll to room temperature or higher.
This is because if the temperature of the roll is lower than room temperature, the pressure-sensitive adhesive liquid will not be sufficiently dried at the convex portions, and it will be difficult to control the height and depth of the irregularities. Further, in order to maintain the fluidity of the applied pressure-sensitive adhesive layer during the roll treatment, 1 se of the coating liquid (pressure-sensitive adhesive liquid) is used.
The apparent viscosity at a shear rate of c -1 is preferably 20 centipoise or less. The concentration of the pressure-sensitive adhesive component in the coating solution depends on the pressure-sensitive adhesive material, but may be in the range of 1 to 70% by weight.

By drying No. 2, a tape 15 having unevenness on the pressure-sensitive adhesive layer 13 as shown in D of FIG. 1 was obtained. At this time, a protrusion is formed on the pressure-sensitive adhesive layer on the film corresponding to the protrusion on the surface of the roll 20. The height of the protrusions of the dried pressure-sensitive adhesive layer was about 4 μm from the surface of the support film 11. The pressure-sensitive adhesive layer is lined with unevenness of 250 μm pitch, which is linear in the lateral direction, and the depth from the top of the convex portion to the valley of the concave portion is 900 nm (the depth of the concave portion is about 23% of the height of the convex portion).

態を示す。One of the most suitable ones is to be used as a length measuring tape for an object having a curved surface. Generally, it is very difficult to accurately measure the length of a curved surface of an object to be measured. However, as shown in FIG. 2, the adhesive tape 15 of the present invention is attached on the curved surface of the DUT 40, and the number of waves between two specific points to be measured next is counted. From the numerical value of the wave pitch (interval) measured in advance,
You can know the distance on the curved surface accurately. If the wave pitch is set to a unit length (for example, 0.1 mm) in advance and the wavy pattern is used as a scale, the length can be easily measured with the same usability as a general ruler. In addition, in FIG.
Is an enlarged cross-sectional view of the tape 15, and B shows a state of measuring the length.
