<P>PROBLEM TO BE SOLVED: To provide an adhesive double coated tape for fixing abrasive which has low initial tackiness, is easy to re-stick to a surface plate but rigidly stuck by pressing, and is free from such problems that the abrasive peels by mechanical shock during grinding once stuck to the surface plate, and the abrasive peels if abrasive grain liquid or the like with a variety of physical properties is used, as well as which does not peel from the surface plate, and can be peeled without leaving paste on the surface plate after use. <P>SOLUTION: An adhesive layer for fixing the surface plate is formed of a pressure-sensitive adhesive containing a (meth)acrylic alkyl-ester-based copolymer of obtained by copolymerizing a polymerizing monomer in a polymerizing monomer mixture containing ≥70 wt.% and <90 wt.% of (meth)acrylic butyl, and 10-40 pts.wt. of tackifier resin selected from a group consisting of rosin-based resin and terpene-based resin with respect to a solid content of 100 pts.wt. of the (meth)acrylic alkyl-ester-based copolymer. <P>COPYRIGHT: (C)2010,JPO&INPIT |
