Title
(EN) CONDUCTIVE INK
(FR) ENCRE CONDUCTRICE
(JA) 導電性インク
Abstract
(EN) The purpose of the present invention is to provide a conductive ink that can form wiring or the like on a substrate through printing and that has excellent adhesion to the substrate. The conductive ink according to the present invention contains components (A), (B), (C), and (D). The ratio (component (C)/component (D) between component (C) and component (D) is 1 or higher. Component (A): Surface-modified metal nanoparticles having a configuration in which the surfaces of metal nanoparticles (a-1) are coated with an organic protective agent (a-2). Component (B): Solvent. Component (C): Polyvinyl acetate. Component (D): Polyvinyl acetal.
(FR) La présente invention concerne une encre conductrice qui peut former un câblage ou analogue sur un substrat par impression et qui a une excellente adhérence au substrat. L’encre conductrice selon la présente invention contient les constituants (A), (B), (C) et (D). Le rapport constituant (C)/constituant (D) entre le constituant (C) et le constituant (D) est de 1 ou plus. Constituant (A) : Nanoparticules métalliques modifiées en surface ayant une configuration dans laquelle les surfaces des nanoparticules métalliques (a-1) sont revêtues d’un agent protecteur organique (a-2). Constituant (B) : Solvant. Constituant (C) : Poly(acétate de vinyle). Constituant (D) : Polyvinylacétal.
(JA) 本開示は、印刷により配線等を基板に形成することができ、且つ基板に対する密着性に優れる導電性インクを提供することを目的とする。 本開示の導電性インクは、下記(A)、(B)、(C)、及び(D)成分を含有する導電性インクであって、(C)成分と(D)成分の比((C)成分/(D)成分)が、1以上である。 (A)成分:金属ナノ粒子(a-1)の表面が、有機保護剤(a-2)で被覆された構成を有する表面修飾金属ナノ粒子 (B)成分:溶剤 (C)成分:ポリ酢酸ビニル (D)成分:ポリビニルアセタール
