Abstract
A re-peeling pressure-sensitive adhesive or a re-peeling pressure-sensitive adhesive tape satisfying four conditions, besides (3) and (4), (1) and (2) or (1') and (2'): (1) the average releasing force in each releasing rate in the case of releasing at a releasing rate of from 10 to 100 meters/minute is from 50 to 1,000 g/25 mm, (2) the difference between the maximum value and the minimum value of the releasing force of the releasing chart pattern obtained by the release in (1) is not larger than 2/3 of the average releasing force or not larger than 500 g/25 mm, (1') the average releasing force in each releasing rate in the case of releasing at a releasing rate of from 1 meter/minute to 50 meters/minute is from 100 g/25 mm to 1,000 g/25 mm, (2') in the relation between the releasing force and the releasing rate after adhering to an adherend and preserving, the peak of the releasing force does not exist in the range of the releasing rate of not higher than 50 meters/minute, (3) the rolling initial tacking force is from 30 to 800 g/25 mm, and (4) the retentive force is at least 15 minutes under a load of 500 g. The pressure-sensitive adhesive and pressure-sensitive adhesive tape can b…
