Title (EN) AQUEOUS METAL NANOPARTICLE DISPERSION
(FR) DISPERSION AQUEUSE DE NANOPARTICULES MÉTALLIQUES
(JA) 金属ナノ粒子水分散液
Abstract:
(EN) The present invention provides an aqueous metal nanoparticle dispersion which contains composite bodies of metal nanoparticles (X) and an organic compound (Y) (excluding composite bodies wherein the organic compound (Y) is a polyvinyl pyrrolidone) and a polyvinyl pyrrolidone (Z). The present invention also provides the aqueous metal nanoparticle dispersion wherein the organic compound (Y) is a polymer of a monomer mixture that contains a (meth)acrylic acid monomer having one or more anionic functional groups selected from the group consisting of a carboxy group, a phosphoric acid group, a phosphorous acid group, a sulfonic acid group, a sulfinic acid group and a sulfenic acid group. This aqueous metal nanoparticle dispersion has excellent dispersion stability even in cases where a thermal load such as heating or freezing and subsequent melting that may occur during storage or transportation is applied thereto, while exhibiting surface activity and sufficient adsorption to a substrate.
(FR) La présente invention concerne une dispersion aqueuse de nanoparticules métalliques qui contient des corps composites de nanoparticules métalliques (X) et un composé organique (Y) (à l'exclusion de corps composites dans lesquels le composé organique (Y) est un polyvinyl pyrrolidone) et un polyvinyl pyrrolidone (Z). La présente invention concerne également la dispersion aqueuse de nanoparticules métalliques dans laquelle le composé organique (Y) est un polymère d'un mélange de monomères qui contient un monomère acide (méth)acrylique comprenant un ou plusieurs groupes fonctionnels anioniques choisis dans le groupe constitué par un groupe carboxy, un groupe acide phosphorique, un groupe acide phosphoreux, un groupe acide sulfonique, un groupe acide sulfinique et un groupe acide sulfénique. Ladite dispersion aqueuse de nanoparticules métalliques présente une excellente stabilité de dispersion même dans des cas où une charge thermique telle qu'un chauffage ou une congélation suivie d'une fusion susceptibles de se produire pendant le stockage ou le transport lui sont appliquées, tout en présentant une activité de surface et une adsorption suffisante à un substrat.
(JA) 本発明は、金属ナノ粒子(X)及び有機化合物(Y)の複合体(前記有機化合物(Y)がポリビニルピロリドンである複合体を除く。)と、ポリビニルピロリドン(Z)とを含有する金属ナノ粒子水分散液を提供する。さらには、前記有機化合物(Y)が、カルボキシ基、リン酸基、亜リン酸基、スルホン酸基、スルフィン酸基及びスルフェン酸基からなる群から選ばれる1種以上のアニオン性官能基を有する(メタ)アクリル酸系単量体を含有する単量体混合物の重合物である金属ナノ粒子水分散液を提供する。該金属ナノ粒子水分散液は、貯蔵時や輸送時に起こりうる、加温、又は凍結後に融解するといった熱的負荷が加えられても優れた分散安定性を有し、かつ基材への十分な吸着性、及び、表面活性を有する。
