<p><P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition which does not need a seasoning time when converted into a pressure-sensitive adhesive, does not cause performance change of the pressure-sensitive adhesive even when exposed to a cruel environment for a long term, and does not cause functional change by suppressing expansion and contraction etc., of a base material etc., to which the pressure-sensitive adhesive is applied; and to provide the pressure-sensitive adhesive and an optical film. <P>SOLUTION: The pressure-sensitive adhesive composition includes (A) 100 pts.wt. of a (meth)acrylate polymer with a weight-average molecular weight of 200,000-2,500,000, (B1) 1-100 pts.wt. of a reactive (meth)acrylate polymer having a weight-average molecular weight of 30,000-1,500,000 and ethylenic double bonds in its side chains, (B2) 1-50 pts.wt. of a polyene compound having two or more ethylenic double bonds, and (C) 0.01-50 pts.wt. of a polythiol compound having two or more mercapto groups. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
