<P>PROBLEM TO BE SOLVED: To provide an adhesive composition, an adhesive and an adhesive sheet, which have light diffusability, and are excellent in stress relaxation, unevenness conformability and durability when applied to optical members such as polarizing plates. <P>SOLUTION: The adhesive composition contains a first (meth)acrylate ester polymer (A) having a weight-average molecular weight of 500,000 to 3,000,000, a second (meth)acrylate ester polymer (B) having a weight-average molecular weight of 8,000 to 300,000, a crosslinking agent (C), and a light diffusing microparticle (D), wherein the proportion of (B) to 100 pts.mass of (A) is 5 to 50 pts.mass; (B) contains a monomer having a functional group (b1) reactive with (C); (A) contains no monomer having a functional group reactive with (C) or contains a monomer having a functional group (a1) having a lower reactivity with (C) than the functional group (b1) of (B); and the content of (D) is 5.0 to 50.0 pts.mass with respect to 100 pts.mass of the total of (A) and (B). <P>COPYRIGHT: (C)2013,JPO&INPIT |
