Title:
AQUEOUS METAL NANOPARTICLE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2018/038086
Kind Code:
A1
Abstract:
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.
