Abstract: A fingerprint-resistant pressure-sensitive adhesive tape includes has a core layer including a substrate layer and a colored layer, a pressure-sensitive adhesive layer, and a fingerprint-resistant treated layer. The substrate layer is formed of a plastic material, such as polyethylene terephthalate. The colored layer is laminated on one major surface of the substrate layer. The colored layer is a black printed layer formed, for example, by printing black ink. The pressure-sensitive adhesive layer is laminated on a major surface of the colored layer, the major surface being opposite to the substrate layer. An acrylic polymer is preferably used for the pressure-sensitive adhesive layer. The fingerprint-resistant treated layer is formed on a major surface of the substrate layer, the major surface being opposite to the colored layer. Wa of the outer surface of the fingerprint-resistant treated layer is 150 angstroms or more and Ra thereof is 2000 angstroms or more.

Abstract: A translucent light-shielding tape has a base material layer, a light-shielding layer and an adhesive agent layer. The base material layer is formed with a plastic material such as polyethylene terephthalate and the like. The light-shielding layer is laminated on one of the main surfaces of the base material layer. The light-shielding layer is, for example, a black print layer formed with printing of black ink. The adhesive agent layer is laminated on the other of the main surfaces of the base material layer. As the adhesive agent layer, an acrylic-based polymer is suitably used. The translucent light-shielding tape has 0.010 to 10% of the permeability with regards to light of 550 nm.

Abstract: A double-sided pressure-sensitive adhesive tape includes: a substrate; a first pressure-sensitive adhesive layer provided on one surface of the substrate; and a second pressure-sensitive adhesive layer provided on the other surface of the substrate. At least one of the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer contains both an acrylic polymer and an acrylic oligomer whose weight average molecular weight is 20000 or less and whose monomer is different from that of the acrylic polymer. The content of a tackifier for providing tackiness is less than 5% by mass. By containing the acrylic oligomer whose monomer is different from that of the acrylic polymer in at least one of the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer, the drop impact resistance in a low-temperature atmosphere is improved.
