    Abstract: There are provided a silver ink composition which is capable of forming metallic silver having sufficient electrical conductivity without carrying out a heat treatment at high temperatures; and a conductor and communication device which are obtained using this silver ink composition. Such a silver ink composition is characterized by being obtained by blending: a silver carboxylate having a group represented by a formula “—COOAg”; one or more nitrogen-containing compounds selected from the group consisting of amine compounds and quaternary ammonium salts of not more than 25 carbon atoms, ammonia, and ammonium salts obtained by reacting the above amine compounds or ammonia with an acid; and one or more reducing compounds selected from the group consisting of oxalic acid, hydrazine and compounds represented by a general formula (5) shown below (in the formula, R21 represents an alkyl group, alkoxy group or N,N-dialkylamino group of not more than 20 carbon atoms, a hydroxyl group or an amino group): or obtained by preparing a second mixture by supplying carbon dioxide to a first mixture formed by mixing a silver carboxylate having a group represented by a formula “—COOAg” and one or more nitrogen-containing compounds selected from the group consisting of amine compounds and quaternary ammonium salts of not more than 25 carbon atoms, ammonia, and ammonium salts obtained by reacting the amine compounds or ammonia with an acid; and further mixing one or more reducing compounds selected from the group consisting of oxalic acid, hydrazine and compounds represented by a general formula (5) shown below to the mixture: H—C(═O)—R21 (5).

    Abstract: This IC card is provided with a module having an inlet, an adhesive layer covering the module, and a first base material and second base material sandwiching the module with interposition of the adhesive layer. The module is disposed on one face of the first base material with interposition of a viscous layer which has a thickness that varies according to the thickness at each area of the module, and its two ends are narrower than its other parts when viewed from the outer face side of the first base material or the outer face side of the second base material. According to this IC card, it is possible to offer the IC card with a flat surface, and without occurrence of strain in the embedded IC chip.

    Abstract: Satisfactory anti-blocking property of powder toner can be realized, while avoiding increase in softening temperature of the powder toner, by coating the surface of a low melting point powder toner with a thermosetting resin. This leads to the realization of toner fixing at lower temperatures and is particularly effective when using a urea resin as the thermosetting resin or employing polymerized toner as the powder toner. Use of the surface-coated powder toner with a low softening temperature and less blocking tendency makes possible reduction of thermal energy and time required for fusing, thereby realizing energy-saving and high-speed fusing process.

    Abstract translation: 通过用热固性树脂涂覆低熔点粉末调色剂的表面，可以避免粉末调色剂的防粘连性，同时避免粉末调色剂的软化温度升高。 这导致在较低温度下实现调色剂定影，并且在使用脲树脂作为热固性树脂或使用聚合调色剂作为粉末调色剂时特别有效。 使用具有低软化温度和较少阻塞倾向的表面涂覆粉末调色剂可以降低热能和熔化所需的时间，从而实现节能和高速熔融工艺。
