Abstract: An objective of the present invention is to provide an organic glass laminate that exhibits excellent weathering resistance and abrasion resistance, and that can be used as an exterior member. This organic glass laminate comprises at least the following, in order: an organic glass base, a cured layer formed from the cured product of a resin composition, which comprises a curable resin and a UV absorber agent; and an inorganic oxide film. The glass transition temperature of the cured product which constitutes the cured layer is adjusted to 80-160° C., and the thickness of the inorganic oxide film is set to at least 0.01 ?m and less than 0.5 ?m, whereby weathering resistance and abrasion resistance are significantly improved, and the organic glass laminate is made suitable for use as an exterior member.

Abstract: A method for manufacturing noble metal fine particles, by which noble metal fine particles are obtained whose particle diameter and alloy composition are easy to control and whose crystallinity and purity are high, is provided. The method includes the steps of: (1) obtaining a molten mixture containing a noble metal chloride, by insufflating chlorine gas into a mixture of a molten salt of an alkali metal chloride and a noble metal; (2) obtaining a noble metal oxide as a precipitate by adding an alkali metal carbonate to the molten mixture under an inert gas atmosphere; (3) obtaining a mixture containing noble metal oxide fine particles, by pulverizing the noble metal oxide with at least one of an alkali metal carbonate and an alkali earth metal carbonate; and (4) obtaining noble metal fine particles by heating the mixture obtained in step (3) under an atmosphere of gas containing hydrogen, and then treating the heat-treated mixture with acid.
