Abstract: The present invention provides a silver coating composition that develops excellent conductivity (low resistance value) by low-temperature and short-time calcining and that has excellent printability. A silver particle coating composition including: silver nano-particles whose surfaces are coated with a protective agent including an aliphatic hydrocarbon amine; and a dispersion solvent, wherein the dispersion solvent includes a solvent selected from the group consisting of a glycol ether-based solvent and a glycol ester-based solvent. The silver particle coating composition is suitable for various printing methods such as intaglio offset printing and screen printing.

Abstract: Provided is an adhesive as follows. The adhesive can bond/secure an adherend to a support with maintaining high adhesiveness during the existence of the need for securing of the adherend to the support, even in a high-temperature environment or in an environment with abrupt temperature change. The adhesive enables debonding of the adherend from the support without breakage of the adherend when the securing becomes unnecessary. The adhesive can be easily removed when remained on the adherend after debonding. The adhesive according to the present invention contains (A) a multivalent vinyl ether compound, (B) a compound including two or more of a constitutional unit represented by Formula (b), and (C) a thermoplastic resin. In the formula, X is selected from hydroxy and carboxy.

Abstract: The present invention provides silver nano-particles that are excellent in stability and develop excellent conductivity by low-temperature calcining, a method for producing the silver nano-particles, and a silver coating composition comprising the silver nano-particles. A method for producing silver nano-particles comprising: mixing a silver compound with an aliphatic amine comprising at least a branched aliphatic hydrocarbon monoamine (D) comprising a branched aliphatic hydrocarbon group and one amino group, said branched aliphatic hydrocarbon group having 4 or more carbon atoms, to form a complex compound comprising the silver compound and the amine; and thermally decomposing the complex compound by heating to form silver nano-particles.
