  • Patent number: 8182574
    Abstract: 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·cm (measurement concentration: 1.6×10?4 mol/L, and solvent: water).

  • Patent number: 7976609
    Abstract: 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.

  • Patent number: 7658791
    Abstract: It is an object of the present invention to provide an anticorrosive coating composition which uses a pollution-free (heavy metal-free) rust preventive pigment and exhibits anticorrosive performances equal or superior to those of lead compounds or chromic acid compounds even if the pigment is blended in various binder resins and also to provide an anticorrosive coating composition having excellent storage stability. The present invention relates to an anticorrosive coating composition comprising a binder resin and a pollution-free (heavy metal-free) rust preventive pigment containing a condensed calcium phosphate produced by baking a single substance or mixture of a calcium component and a phosphorous component in the following atomic ratio (Ca/P=m): 0.50<m<1.00, at 180 to 350° C.
