Abstract
An acrylic adhesive composition comprising an acrylic polymer as a base resin and a modified cyclopentadiene resin having a softening point of at least 60.degree. C. obtained by copolymerizing (a) 85 to 50% by weight of a cyclopentadiene monomer and (b) 15 to 50% by weight of a polar vinyl monomer or a hydrogenation product of said cyclopentadiene resin as a tackifier.
