The present invention provides metal fine particles which have selective wavelength absorption characteristics in a wavelength region from visible light to near infrared light, and have sharp absorption characteristics, and influences little the surrounding wavelength, and therefore, they yield tones having high chroma. The present invention provides metal fine particles wherein an aspect ratio is in a range from 1.1 to 8.0, a maximum absorption wavelength in plasmon absorption is in a range from 400 nm to 1,200 nm, and an absorption coefficient at a peak position of the maximum absorption wavelength is in a range from 6,000 to 20,000 L/mol&#xb7;cm (measurement concentration: 1.6&#xd7;10mol/L, and solvent: water).

Metal fine particles, composition containing the same, and production method for producing metal fine particles

A method for manufacturing metal nanorods includes: a step of adding a reducing agent to a metallic salt solution; a step of radiating light into the metallic salt solution containing the reducing agent; and a step of leaving the light-radiated metallic salt solution containing the reducing agent stationary in a dark place so as to grow metal nanorods. Metal nanorods can be also grown by forming a mixed solution by fractionating the above light-radiated metallic salt solution and mixing the fractionated metallic salt solution into a non-radiated metallic salt solution containing the reducing agent, or mixing a non-radiated metallic salt solution and the reducing agent into the above light-radiated metallic salt solution; and leaving the mixed solution stationary in a dark place so as to grow metal nanorods.

Polyhedral organosilicon compound and method for producing the same

A composition for forming transparent conductive films comprises a tin-containing indium oxide (ITO) powder dispersed in a binder solution. The binder solution comprises a mixed organic solvent consisting of at least one polar solvent and at least one non-polar solvent, in which a polymer having a weight-average molecular weight of from 8,000 to 150,000 is dissolved. The polymer contains (a) an acidic functional group in such a proportion that the polymer has an acid number of from 0.5 to 15 mg-KOH/g, or (b) a polyalkylene glycol chain in a proportion of from 0.5% to 40% by weight, or both of (a) and (b) in the molecule. Alternatively, the binder solution comprises an actinic radiation-curable binder, which comprises an acrylate or methacrylate compound containing an acid phosphate group in the molecule. The composition can form, by coating, a transparent conductive film having improved electrical and optical properties.
