Abstract
The present invention provides a double-sided pressure-sensitive adhesive tape or sheet including a bubble-containing pressure-sensitive adhesive layer; and a releasable liner protecting a pressure-sensitive adhesive surface of the bubble-containing pressure-sensitive adhesive layer, said releasable liner comprising at least a releasably treated layer formed by an ionizing radiation-curable silicone type releasing agent, in which the releasably treated layer formed by the ionizing radiation-curable silicone type releasing agent is employed onto a pressure-sensitive adhesive surface on the heavier releasable side. The double-sided pressure-sensitive adhesive tape or sheet may employ a bubble-containing pressure-sensitive adhesive layer formed by a bubble-containing pressure-sensitive adhesive composition in the form in which a gas component is mixed in a pressure-sensitive adhesive composition.
