Abstract
A polyester pressure-sensitive adhesive composition is provided including a polyester resin having a predetermined amount of a structural unit derived from a hydrogenated polybutadiene structure-containing compound, or a polyester resin having a structural unit derived from a hydrogenated polybutadiene structure-containing compound and a predetermined amount of a structural unit derived from an aromatic ring structure-containing compound. The polyester pressure-sensitive adhesive composition has superior adhesion to a polyolefin base material and is highly transparency.
