Abstract

A polyester-based pressure-sensitive adhesive layer, pressure-sensitive adhesive tape, and double-coated pressure-sensitive adhesive tape each having high durability (high heating humidification storage stability) and good adhesive properties are provided using a polyester-based pressure-sensitive adhesive composition. The polyester-based pressure-sensitive adhesive composition of the invention includes a polyester, a hydrolysis-resistant agent, a tackifier with an acid value of 8 or less and a softening point of 80 to 170° C., and a crosslinking agent, and contains 20 to 100 parts by weight of the tackifier based on 100 parts by weight of the polyester.
