<P>PROBLEM TO BE SOLVED: To provide an adhesive composition, an adhesive and an adhesive sheet having antistaticity, and excellent in both of stress relaxation properties and durability, when applied to an optical member such as a polarizer. <P>SOLUTION: This adhesive composition includes: (A) a first (meth)acrylic ester polymer with Mw of 500,000-3,000,000, (B) a second (meth)acrylic ester with Mw of 8,000-300,000, (C) a crosslinking agent and (D) an antistatic agent; where the proportion of (B) is 5-50 pts.mass to 100 pts.mass of (A); (B) includes a monomer having a functional group (b1) reactive with (C) as a constitutive component, and the proportion of the monomer having the functional group (b1) exceeds 1 mass% and less than 50 mass% in (B); and (A) does not include a monomer having a functional group reactive with (C), or includes a monomer having a functional group (a1) with lower reactivity with (C) than the functional group (b1), as a constitutive component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
