The present invention relates to an antiviral dispersion liquid, a method for producing the same, and an antiviral formed product. This dispersion liquid contains copper compound fine particles and a stabilizer in a non-aqueous solvent, and the copper compound fine particles are coated with fatty acid. The copper compound fine particles are dispersed in a dispersion medium homogeneously and stably, thereby to exhibit efficiently the antiviral properties of the copper compound fine particles.

Dispersion liquid, method for producing the same, and copper compound particles

An antibacterial resin composition comprising a thermoplastic resin or a thermosetting resin blended with a metal-carrying compound carrying at least one kind of metal ions selected from the group consisting of Ag, Cu, Zn, Co, and Ni, and a compound represented by the following formula (2): 

Antibacterial resin composition

A dispersion solution containing ultrafine metal particles, comprising a low-boiling solvent and, contained therein, ultrafine metal particles of any one of Ag, Cu or Zn having a fatty acid and a glyceride coordinated on the surfaces thereof. The dispersion solution contains, dispersed therein, ultrafine metal particles that have excellent antibacterial power at a high concentration without being aggregated. The dispersion solution maintains excellent dispersion property even after the passage of long periods of time and also exhibits very high degree of transparency even when it is mixed into a resin composition.

Dispersion solution containing antibacterial ultrafine metal particles and method of producing the same

A curable resin composition including a curable resin in which ultrafine metal particles modified with a fatty acid are dispersed. The ultrafine metal particles are fatty acid-modified ultrafine metal particles having a fatty acid coordinated on the surfaces of the ultrafine metal particles and a glyceride coordinated around the fatty acid or on the surfaces of the ultrafine metal particles.

Curable resin composition having antibacterial power

An antibacterial resin composition comprising a thermoplastic resin or a thermosetting resin blended with at least one kind of fatty acid metal salt selected from Ag, Cu, Zn, Co and Ni, and a compound represented by the following formula (2): 

An antibacterial resin composition comprising a thermoplastic resin or a thermosetting resin that contains a metal compound represented by the following formula (1), permitting the metal such as silver having antibacterial power to efficiently elute out and the eluted metal to remain stable as metal ions so that excellent antibacterial power can be exhibited using only a decreased amount of an expensive compound containing silver or the like,
