The present invention aims to provide an adhesive composition that can exhibit excellent adhesion to both smooth surfaces and rough surfaces. The present invention also aims to provide an adhesive tape including an adhesive layer containing the adhesive composition, as well as a method for fixing and a method for producing an electronic device component or an in-vehicle component using the adhesive tape. Provided is an adhesive composition containing an acrylic copolymer containing a structural unit derived from n-heptyl (meth)acrylate.

Provided is a multilayer body having good print readability and removability. A multilayer body (1) is for a laser marking label and includes a first layer (10) allowing laser light to pass through, a second layer (20) developing a color by laser light, and a third layer (30) having adhesiveness, which are stacked in this order. The second layer (20) consists of a resin composition containing an acrylic-based copolymer, an isocyanate-based crosslinking agent, a color development pigment, and a white pigment. The isocyanate-based crosslinking agent is selected from (i) an aromatic-aliphatic isocyanate-based crosslinking agent or (ii) a mixture of an aliphatic or alicyclic isocyanate-based crosslinking agent and an aromatic isocyanate-based crosslinking agent. A contained amount of the isocyanate-based crosslinking agent is 5-40 parts by mass with respect to 100 parts by mass of the acrylic-based copolymer. The second layer (20) is in contact with the first laver (10).

A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.
