Abstract: Provided is a novel pressure-sensitive adhesive tape having a moderately weak adhesion during a time period from a production process (during its production) to the time of the accomplishment of the product as a result of the completion of the production (immediately after the production). Accordingly, the peeling failure, or the like, resulting from strong adherence of a pressure-sensitive adhesive layer to a roll or the like at the time of the production can be sufficiently suppressed. As a result, stable product supply can be performed. In addition, even after the lapse of about a half day from immediately after the production, the pressure-sensitive adhesive tape can be easily rewound. On the other hand, the pressure-sensitive adhesive tape can express a sufficiently strong adhesion for an adherend after the lapse of a predetermined time from the production (e.g., at the time of its use).

Abstract: Provided is the following novel pressure-sensitive adhesive tape. The pressure-sensitive adhesive tape has a moderately weak adhesion during a time period from a production process (during its production) to the time of the accomplishment of the product as a result of the completion of the production (immediately after the production). Accordingly, the occurrence of a peeling trace, the occurrence of a peeling sound, and the like resulting from strong adherence of a pressure-sensitive adhesive layer to a roll or the like at the time of the production can be sufficiently suppressed. As a result, stable product supply can be performed. On the other hand, the pressure-sensitive adhesive tape can express a sufficiently strong adhesion for an adherend after a lapse of a predetermined time from the production (e.g., at the time of its use).
