<p><P>PROBLEM TO BE SOLVED: To provide an acrylic pressure-sensitive adhesive tape or sheet exhibiting high bond strength initially at low temperature. <P>SOLUTION: The acrylic pressure-sensitive adhesive tape or sheet has an acrylic pressure-sensitive adhesive layer containing a bubble-containing inorganic filler, provided that the layer comprises an acrylic polymer formed from an acrylic monomer mixture comprising (a) an alkyl (meth)acrylate having a 1-14C alkyl group and (b) a vinyl monomer having a polar group in a weight ratio [(a)/(b)] of from 95/5 to 91/9, an inorganic filler in an amount equal to or larger than 0.1 pts.wt. but smaller than 2 pts.wt. based on 100 pts.wt. total of monomer components forming the acrylic polymer, and bubbles. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
