Pressure-sensitive adhesive compostion and pressure-sensitive adhesive sheets
Abstract
A pressure-sensitive adhesive composition excellent in the pressure-sensitive adhesive property and the heat resistance comprises a polyester having a polylactone structure as the main chain. A pressure-sensitive adhesive sheet being excellent in releasing property of a peelable liner and containing no silicone can be obtained by using the pressure-sensitive adhesive composition in combination with a polyolefin film without being subjected to a silicone treatment as a peelable liner. When the pressure-sensitive adhesive sheet comprises a base material having formed thereon the layer of the pressure-sensitive adhesive composition and the back side of the base material has a surface composed of a polyolefin, neither a peelable liner nor a silicone treatment is required. The pressure-sensitive adhesive sheet is suitably used for computer instruments etc., because it contains no silicone.
