Pressure-sensitive adhesive tape roll

A pressure-sensitive adhesive tape roll comprising a bobbin and a double-sided pressure-sensitive adhesive tape helically wound around the bobbin, the double-sided pressure-sensitive adhesive tape satisfying all the following conditions (1) to (5):

• (1) the double-sided pressure-sensitive adhesive tape includes a pressure-sensitive adhesive body having two adhesive faces as both sides thereof, a release liner A arranged on one of the two adhesive faces, and a release liner B arranged on the other adhesive face;
• (2) the pressure-sensitive adhesive body includes at least a pressure-sensitive adhesive layer containing bubbles and/or hollow microspheres;
• (3) the release liner A essentially contains at least one resin selected from the group consisting of low-density polyethylenes, linear low-density polyethylenes, and ethylene-vinyl acetate resins;
• (4) the release liner B essentially contains at least one olefinic resin;
• and
• (5) the release liner A has a width larger than the width of the pressure-sensitive adhesive body, wherein each outer edge of the release liner A extends past each out edge of the pressure pressure-sensitive adhesive body,
• wherein all the following conditions (a), (b), and (c) are satisfied in portions occupying 70% or more of the total length of said tape:
• (a) at least part of the width of the release liner A of an (n) th-turn portion of the tape vertically overlaps the pressure-sensitive adhesive body of an adjacent (n+1) th-turn portion of the tape to form an overlapping portion;
• (b) the width of the overlapping portion is one half or more of the width of the pressure-sensitive adhesive body;
• and
• (c) the pressure-sensitive adhesive body of the (n) th-turn portion of the tape does not vertically overlap the pressure-sensitive adhesive body of the adjacent (n+1) th-turn portion of the tape.
