  • Each tensile speed (10 m / min, 30 m / min) of the adhesive tape in the 180 ° peel adhesive test corresponds to the speed at which a person peels the adhesive tape from the adherend by hand.
  • the pressure-sensitive adhesive tape 10 of Example 1 includes a rubber-based pressure-sensitive adhesive layer 20 made of the rubber-based pressure-sensitive adhesive composition I. As shown in Table 1, no adhesive remains on the aluminum plate even if the adhesive tape 10 of Example 1 is affixed to the aluminum plate and then peeled off at any tensile speed condition after 48 hours. Was confirmed. Moreover, it was confirmed that the adhesive tape 10 of Example 1 was provided with sufficient holding power as a masking application.
  • the adhesive tape 11 of Example 2 was also attached to the aluminum plate as in Example 1, and even if it was peeled off at any tensile speed condition after 48 hours, the aluminum plate It was confirmed that no adhesive remained on the top. Moreover, it was confirmed that the adhesive tape 11 of Example 2 was provided with sufficient holding power as a masking application.
  • the pressure-sensitive adhesive tape A of Comparative Example 1 in which the pressure-sensitive adhesive layer is made of the acrylic pressure-sensitive adhesive composition A has sufficient holding power as a masking application, but the peel pressure-sensitive adhesive force under any tensile speed condition.
  • the adhesive remained on the aluminum plate. This is because the adhesiveness (initial adhesiveness) of the adhesive tape A to the adherend is too high, and the cohesive force of the adhesive layer is insufficient, so that when the adhesive tape A of Comparative Example 1 is peeled off, the adhesive It is considered that a part of the pressure-sensitive adhesive layer remained on the aluminum plate side due to the interlayer breakdown. It was confirmed that the adhesive remained on the aluminum plate in the form of scattered adhesives under any tensile speed conditions.
  • Example 1 when the adhesive tape B of the comparative example 2 which an adhesive layer consists of acrylic adhesive composition B was peeled off by low speed conditions (tensile speed of 10 m / min) in the said peel adhesive force test, Example 1 is shown. As with, no adhesive residue was found on the aluminum plate. However, in the peel adhesive strength test, it was confirmed that the adhesive remained on the aluminum plate when the adhesive tape B of Comparative Example 2 was peeled off under high speed conditions (tensile speed of 30 m / min). In the pressure-sensitive adhesive tape B of Comparative Example 2, it is considered that when peeled off under high speed conditions (tensile speed of 30 m / min), the pressure-sensitive adhesive layer was destroyed and a part of the pressure-sensitive adhesive layer remained on the aluminum plate side.
  • the pressure-sensitive adhesive tape B of Comparative Example 2 has a smaller peel adhesive value than the pressure-sensitive adhesive tape A of Comparative Example 1, and has a value comparable to that of the pressure-sensitive adhesive tape 10 of Example 1. Nevertheless, in the adhesive tape B of Comparative Example 2, when the peeling is performed under a high speed condition (tensile speed of 30 m / min), adhesive residue is generated. This suggests that good peelability cannot be obtained only by suppressing the value of the peel adhesive strength. In addition, the adhesive tape B of the comparative example 2 was provided with sufficient holding force similarly to the adhesive tape 10 of Example 1.
  • the adhesive tape When the adhesive tape is fixed to the adherend while holding other members, as in masking applications, the adhesive tape must have a sufficient holding force that does not peel off from the adherend. Is required. In an adhesive tape, it is very difficult to achieve both sufficient holding power and good peelability that does not cause adhesive residue on the adherend. For example, even if the 180 ° peel adhesive force is controlled, it is not possible to obtain an adhesive tape having both good peelability and holding power.
  • the pressure-sensitive adhesive tape 10 of Example 1 by using a predetermined rubber-based pressure-sensitive adhesive layer as the pressure-sensitive adhesive layer and using a metal foil as the base material, sufficient holding power and good peelability for masking applications can be obtained. It was confirmed that
  • the pressure-sensitive adhesive tape 11 of Example 2 uses a predetermined rubber-based pressure-sensitive adhesive layer similar to that of Example 1 as the pressure-sensitive adhesive layer, and uses a metal foil with an undercoat layer as a base material, thereby masking applications. It has been confirmed that it has both a sufficient holding power and good releasability while also having a throwing power (adhesive strength of the rubber-based pressure-sensitive adhesive layer to the base material). That is, the pressure-sensitive adhesive tape 11 of Example 2 can more reliably peel the rubber-based pressure-sensitive adhesive layer from the adherend without any adhesive residue.
