The double-faced pressure-sensitive adhesive sheet comprises a pressure-sensitive adhesive layer; a first release sheet including at least a first release agent layer attached to one surface of the pressure-sensitive adhesive layer; and a second release sheet including at least a second release agent layer attached to the other surface of the pressure-sensitive adhesive layer. The first release agent layer is mainly constituted of an olefin-based resin and the second release agent layer is mainly constituted of a diene-based polymer material. When an peeling force of the first release sheet with respect to the pressure-sensitive adhesive layer is defined as “X” [mN/20 mm] and an peeling force of the second release sheet with respect to the pressure-sensitive adhesive layer is defined as “Y” [mN/20 mm], the following relation is satisfied: Y−X≧50. The pressure-sensitive adhesive layer, the first release agent layer and the second release layer contain substantially no silicone compound and substantially no halogen compound.

    摘要： There are disclosed a releasing sheet comprising a substrate and a releasing agent layer which is installed by coating the substrate with a releasing agent liquid containing 1,4-polybutadiene and an antioxidant, and irradiating the coated layer with ultraviolet ray so that the layer is cured; and also a releasing sheet comprising in turn a substrate, an undercoat layer which is formed thereon and is composed of an elastic body, and a releasing agent layer which is installed on the undercoat layer by coating the same with a releasing agent liquid containing 1,4-polybutadiene and an antioxidant, and irradiating the layers with ultraviolet ray so that the layers are cured. Being of non-silicone base, the releasing sheets are excellent in releasability from a tacky adhesive agent layer and adhesiveness to the substrate.

The releasing agent layer 11 is composed of a material containing substantially no silicone compound. The releasing agent layer 11 is mainly composed of an elastomer and has a Young's modulus of 1.5 GPa or less. Preferred examples of the elastomer include polybutadiene rubber (especially, 1,4-polybutadiene rubber), polyisoprene rubber, and ethylene propylene rubber. The release sheet 1 has excellent releasability and has little adverse effect on electric components and the like.
