Abstract
The pressure-sensitive adhesive tape of the present invention is a pressure-sensitive adhesive tape comprising a pressure-sensitive adhesive layer comprising a photo-cured acrylic resin, a metal having a lower potential than that of iron, and an electroconductive material, wherein the pressure-sensitive adhesive layer has a total light transmittance X, per micrometer of the thickness, of 99.85% or less, and the pressure-sensitive adhesive layer has a total light transmittance Y of 6% or more. The present invention can provide a pressure-sensitive adhesive tape having a great adhesive force on both the front side and the back side and having good sacrificial corrosion resistance.

A pressure-sensitive adhesive tape comprising a pressure-sensitive adhesive layer comprising a photo-cured acrylic resin, a metal having a lower potential than that of iron, and an electroconductive material other than the metal, the pressure-sensitive adhesive layer having a total light transmittance X, per micrometer of a thickness thereof, of 99.85% or less, and the pressure-sensitive adhesive layer having a total light transmittance Y of 6% or more,
- wherein the content of the metal having a lower potential than that of iron in the pressure sensitive adhesive layer is 3 to 25 mass % based on the total mass of the pressure sensitive adhesive layer,
- wherein the electroconductive material comprises a carbon nanotube,
- wherein the content of the carbon nanotube in the pressure-sensitive adhesive layer is 0.005 to 0.7 mass % based on the total amount of the pressure-sensitive adhesive layer, and
- wherein the thickness of the pressure-sensitive adhesive layer is 200 to 1500 μm.
