Abstract: The present invention provides an RFID inlet antenna comprising a resin base film and a metallic circuit formed via an adhesive layer on the surface of the resin base film. The RFID inlet antenna is prevented from removal of the metallic circuit by unauthorized detachment after the RFID inlet antenna is bonded to an item by a bonding material disposed in such a manner as to cover the metallic circuit.

Abstract: A solar cell rear surface protection sheet having two or more substrates laminated together by means of an adhesive, the adhesive includes a urethane resin obtained by mixing an acrylic polyol, an isocyanate compound, 3-glycidoxypropyltriethoxysilane, and tin octylate. The acrylic polyol is obtained by polymerizing polymerizable monomers, which include a hydroxyl group-containing monomer and other monomers. The other monomers include acrylonitrile. The isocyanate compound includes both a xylylene diisocyanate monomer and hexamethylene diisocyanate isocyanurate, and the xylylene diisocyanate monomer is present in an amount of 20 to 40 wt %, and the hexamethylene diisocyanate isocyanurate is present in an amount of 80 to 60 wt %. The equivalent ratio of isocyanate groups of the xylylene diisocyanate monomer and the hexamethylene diisocyanate isocyanurate to hydroxyl groups of the acrylic polyol is 1.0 to 3.0.

Abstract: A back side protective sheet disposed on a back side of a solar cell module and including a first film containing linear low-density polyethylene having a density greater than or equal to 0.91 g/cm3 and less than or equal to 0.93 g/cm3 and an inorganic ultraviolet absorbing agent; and a second film being laminated on the first film, with a urethane adhesive layer being interposed therebetween. An average particle diameter of the inorganic ultraviolet absorbing agent is greater than or equal to 0.1 ?m and less than or equal to 5 ?m. The first film contains the inorganic ultraviolet absorbing agent greater than or equal to 0.1% by mass and less than or equal to 30% by mass.
