PROBLEM TO BE SOLVED: To provide an epoxy-based insulating ink for IC media usable as an insulating material for IC media in view of the facts of having no oxidative polymerization inhibitory action, having high coatability on substrate surface, and because of being very slightly foamable, producing no pinholes even on forming an electrical insulation layer by a single coating operation and therefore having no problem of short-circuit antenna. SOLUTION: This epoxy-based insulating ink for IC media essentially comprises (A) a cationically polymerizable epoxy resin, (B) a cationic photopolymerization initiator, (C) a particulate filler and (D) a sorbitan ester-type nonionic surfactant.

PROBLEM TO BE SOLVED: To provide the formation method of an RF-ID medium for which electric connection is not interrupted even when external force is concentrated on a conductive part for connection by strongly conducting and joining an IC chip mounted interposer and an antenna holding body. SOLUTION: The IC chip mounted interposer is formed by providing a conductive pattern provided with at least the conductive part for the connection on a base material and mounting an IC chip on the conductive part for the connection and the antenna holding body is formed by providing the conductive pattern composed of an antenna conductive part and the conductive part for the connection positioned at the end part of the antenna conductive part on the base material. The interposer and the antenna holding body are piled up and the respective conductive parts for the connection are conductively joined by using a conductive staple. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To easily manufacture an interposer for a contactless IC medium without need of heat resistance allowing using a sheet with low heat resistance of paper or synthetic resin such as PVC or PET. SOLUTION: Thermosetting conductive ink is printed and hardened on a release sheet 10 with high heat resistance to form opposite lands 5, 7a, 7b and a jumper part 8. Thermosetting insulation ink is printed and cured in such a manner covering the jumper part 8 to form a resist part 6. An IC chip 9 is mounted so as to be connected with the opposite lands 7b, 5. An adhesive sheet 11 with low heat resistance is closely contacted with the sheet 10 and torn off again, and the opposite lands 5, 7a, 7b the resist part 6, the jumper part 8 and the IC chip 9 are integrally transferred to an adhesive face of the adhesive sheet 11. The interposer 4 manufactured in such a manner is adhered to a sheet material 1 having an antenna 3 in a plurally wound coil shape and land parts 2a, 2b to finally form the contactless IC medium.

PROBLEM TO BE SOLVED: To easily manufacture a contactless IC medium at a low cost using sheet type base material made of paper or synthetic resin such as PVC or PET without need of heat resistance. SOLUTION: Thermosetting conductive ink is printed and cured on a release sheet 1 with high heat resistance to form an antenna 3 in a plurally wound coil shape and a land. An adhesive sheet 11 is closely contacted with the sheet 1 and torn off again, and the antenna 3 and the land are transferred to an adhesive face of the adhesive sheet 11. An interposer 4 whereon opposite lands 5, 7b, resist part and a jumper part are previously formed and an IC chip 9 is mounted is adhered to the adhesive face of the adhesive sheet 11. Thereby the IC chip 9 of the interposer 4 is connected with the land at one end of the antenna via the opposite land 5, the jumper part and the opposite land and is connected with the land at the other end of the antenna via the opposite land 7b.

PROBLEM TO BE SOLVED: To obtain an adhesive for laminating non-contact IC media which allows no curling of products, shows an excellent heat resistance and adhesion, has an excellent flexibility allowing no peeling off at bending or twisting when used on non-contact IC media and provides highly reliable non-contact IC media. SOLUTION: This adhesive is used for laminating, on a substrate having an IC chip-mounted antenna, other parts of the substrate or other substrates. The adhesive contains an epoxy compound, a hardener and a flexibility- imparting agent.

PROBLEM TO BE SOLVED: To provide a sealant which does not peel off even by the application of force such as bending, compression and torsion when a non-contact type IC medium is used and prevents an IC chip from being destroyed and from being separated from a base material, a method for sealing the IC chip by using the sealant, and a method for manufacturing the non-contact type IC medium by using the sealant. SOLUTION: This sealant includes an electron beam curable component including a compound to be cured by electron beams as the main component. It is desirable to use a sealant that further includes a softening agent to give flexibility. The sealant is applied to the IC chip mounted on the non-contact type IC medium, the sealant is irradiated with electron beams to be cured, and the IC chip is thereby sealed.
