SILVER MICROPARTICLE DISPERSION LIQUID

Through the present invention, there is manufactured a silver microparticle dispersion liquid including silver microparticles (the silver content in the silver microparticle dispersion liquid being 30-95% by mass) covered by a C8-12 amine such as octylamine as an organic protectant and having an average primary particle diameter of greater than 100 nm and 300 nm or less, a polar solvent (5-70% bymass) having a boiling point of 150-300 DEG C, and an acrylic dispersant (5% by mass or less with respect to the silver microparticles) such as a dispersant comprising an acrylic acid ester and/or a methacrylic acid ester. 本发明的目的是制造种银微粒分散液，其包含：被作为有机保护剂的辛胺等碳数8～12的胺包覆的平均次粒径大于100nm且在300nm以下的银微粒(银微粒分散液中的银的含量为30～95质量％)、沸点为150～300℃的极性溶剂(5～70质量％)、和包含丙烯酸酯以及甲基丙烯酸酯中的至少种的分散剂等丙烯酸类分散剂(相对于银微粒为5质量％以下)。
