ABSTRACT:
There are disclosed a pressure-sensitive adhesive sheet which comprises a substrate sheet, a pressure-sensitive adhesive layer formed on one side of the substrate sheet and a release layer comprising a cured product from an ionizing radiation-curing type releasable resin formed on the other side of the substrate sheet; and a laminate which comprises a plurality of these pressure-sensitive adhesive sheets that are superimposed on one another so that the pressure-sensitive adhesive layer and the release layer directly face each other and the whole surfaces of the pressure-sensitive adhesive layers are covered with the release layers. The above pressure-sensitive adhesive sheets and the laminate formed therefrom can be produced with good workability with a simplified apparatus without the generation of curls, and thus are well suited for use as display labels etc.
