    Abstract: Provided are a polyester-based pressure-sensitive adhesive composition having high wetting ability and superior adherability and light peelability, and a pressure-sensitive adhesive sheet produced with such a pressure-sensitive adhesive composition. The polyester-based pressure-sensitive adhesive composition includes a polyester obtained by polycondensation of a difunctional or polyfunctional carboxylic acid and a diol; a fatty acid ester; and a crosslinking agent, wherein the polyester has a weight average molecular weight of 8,500 to 50,000, and the fatty acid ester has no additional functional group and has a molecular weight of 200 to 700. The polyester-based pressure-sensitive adhesive composition contains 10 to 150 parts by weight of the fatty acid ester based on 100 parts by weight of the polyester.

    Abstract: The purpose of the present invention is to provide: a polyester-based pressure-sensitive adhesive layer, for which a pressure-sensitive adhesive composition (pressure-sensitive adhesive solution) without any acrylic pressure-sensitive adhesive or the like which needs a large amount of an organic solvent and is difficult to apply thickly; to provide a polyester-based pressure-sensitive adhesive layer that is friendly to the global environment, can be applied thickly, has a high level of cost effectiveness and workability, and also has a high level of adhesion, retention, and repulsion resistance; and to provide a pressure-sensitive adhesive tape or double-sided pressure-sensitive adhesive tape having such a pressure-sensitive adhesive layer. The invention is directed to a polyester-based pressure-sensitive adhesive layer including a product made from a polyester-based pressure-sensitive adhesive composition including: a polyester obtained by polycondensation of at least a dicarboxylic acid component and a diol component; and a tackifier, the polyester-based pressure-sensitive adhesive layer having a gel fraction of 15% by weight or more to less than 40% by weight.
