Metal-microparticle-containing ink

The present invention relates to a metal fine particle-containing ink containing metal fine particles (a) dispersed therein with a polymer B, in which the ink contains an ink solvent S; a difference ΔSP (|SP(S)−SP(B)|) between solubility parameters of the solvent S and the polymer B is not more than...

Beschreibung
Zusammenfassung:	The present invention relates to a metal fine particle-containing ink containing metal fine particles (a) dispersed therein with a polymer B, in which the ink contains an ink solvent S; a difference ΔSP (\|SP(S)−SP(B)\|) between solubility parameters of the solvent S and the polymer B is not more than 1.5 (cal/cm3)0.5 wherein SP(S) and SP(B) are a solubility parameter of the ink solvent S and a solubility parameter of the polymer B, respectively, as measured by a Fedors method; and the SP(B) is not less than 9.5 (cal/cm3)0.5 and not more than 10.5 (cal/cm3)0.5, as well as a method for producing a printed material, which includes the step of applying the metal fine particle-containing ink to a printing substrate to form a metal coating film of the ink on the printing substrate under ordinary-temperature environments, thereby obtaining the printed material.
