Abstract: The present invention provides a masking tape which can be easily released without leaving an adhesive residue. A heat resistant masking tape, comprising (1) a heat resistant backing film layer, and (2) a pressure-sensitive adhesive layer disposed on the heat resistant backing film layer, wherein the adhesive layer comprises a polymer having a solubility parameter (SP) value at 25° C. of 20 MPa0.5 or less.

Abstract: A (meth)acrylic pressure-sensitive adhesive foam reduced in the amount of a foaming adjuvant compared with the conventional foam and having a high air bubble content, and a method for producing the same are provided. The foam includes a partial polymer having (a) one or more alkyl (meth)acrylate monomers having one reactive unsaturated group, the alkyl group having 12 or less carbon atoms, (b) a monomer for crosslinking, which is copolymerizable with the component (a), and (c) a copolymer of the component (a) and the component (b); a thermally conductive filler; and a foaming adjuvant containing surface modified nanoparticles having a particle diameter of 20 nm or less, wherein a crosslinked structure containing the component (c) is formed in the curable composition.

Abstract: A double-coated pressure-sensitive adhesive tape comprising a core material composed of a nonwoven fabric with a thickness of no greater than 20 ?m, and a pressure-sensitive adhesive layer comprising an acrylic-based polymer with a glass transition temperature (Tg) of between ?20° C. and 20° C. and with a weight-average molecular weight of 1 million or greater, on both sides of the core material, the double-coated pressure-sensitive adhesive tape having a total thickness of no greater than 60 ?m.
