<P>PROBLEM TO BE SOLVED: To provide a self-adhesive and a self-adhesive sheet having an antistatic property, and excellent in both stress relaxation and durability when applied to an optical member such as a polarizing plate. <P>SOLUTION: The self-adhesive contains a first (meth)acrylic acid ester polymer (A) having a weight-average molecular weight of 500,000-3,000,000, a component obtained by crosslinking a second (meth)acrylic acid ester polymer (B) having a weight-average molecular weight of 8,000-300,000, and an antistatic agent (C), wherein the elongation at break by a tensile test is 1,500% or more, and a gel fraction is 30-90%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
