Provided is a recording medium for a nail sticker and a method of manufacturing the same, and more particularly, to a recording medium and a method of manufacturing the same, which show that an ink reception layer is formed on a base of a polyurethane material so that a nail sticker can be printed using a sublimation printer. The recording medium for a nail sticker comprises: a release paper; an adhesion layer formed on the release paper; a base of a polyurethane material attached onto the adhesion layer; an undercoating layer formed on the base; and an ink reception layer formed on the undercoating layer.

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).

Materials and methods for mitigating passive intermodulation. 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.
