摘要:
A method for forming a silicon dioxide film according to the present invention comprises steps of: (i) contacting a substrate with processing solution containing silicofluoric acid solution supersaturated with silicon dioxide, and (ii) forming the silicon dioxide film on the substrate; wherein organic colorant(s) is/are introduced into the silicon dioxide film by adding organic colorant(s) to the processing solution. According to the present invention, a silicon dioxide film containing organic colorant without defect such as air bubbles, or undecomposed raw material.

摘要:
A reinforcing material for proton conductive membrane, comprising a nonwoven fabric including, as essential components thereof, glass fibers having a C-glass composition and a binder for strengthening bonding between the glass fibers. The average fiber diameter of the glass fibers is in a range of 0.1 μm to 20 μm, and the average fiber length of the glass fibers is in a range of 0.5 mm to 20 mm. According to the present invention, a reinforcing material excellent in heat resistance, acid resistance, and dimensional stability can be obtained.
摘要:
The present invention provides a light-emitting body in which fine phosphor particles are dispersed in an oxide matrix, with the fine phosphor particles containing at least one selected from oxides and oxysulfides as a parent material. When this light-emitting body is dispersed in a resin, a resin composition having excellent transparency can be obtained. This light-emitting body can be produced by: preparing a gel through a sol-gel process in which a raw material solution containing a compound that supplies metal atoms composing the fine phosphor particles is used; and heating the gel at 400° C. or higher, for example. Preferably, the light-emitting body has a shape of a flake or fiber.

A luminescent-film-coated product includes a substrate, a first layer of a transparent resin matrix containing a phosphorescent material and/or a fluorescent material, and a second layer of a transparent resin matrix containing a shiny pigment made of glass flakes coated with a high-refractive-index metal oxide. Another luminescent-film-coated product includes a substrate and a layer of a transparent resin matrix containing a phosphorescent material and/or a fluorescent material and a shiny pigment. Another luminescent-film-coated product includes a substrate, a first layer of a transparent resin matrix containing a shiny pigment made of glass flakes coated with silver, gold, nickel, or a high-refractive-index metal oxide, and a second layer of a transparent resin matrix containing a phosphorescent material and/or a fluorescent material, in which the shiny pigment has a maximum visible light reflectance of 30% or more. A product coated with a luminescent film, for example, warning/safety signs, position signs, and ornaments having good visibility and design can be provide by suitably combining a phosphorescent or fluorescent material and a shiny pigment.

摘要:
The present invention provides a black brightening flake which prevents fine pigment particles from agglomerating. When incorporated into a cosmetic, a coating material, etc., the flakes enable the resultant composition not only to give a satisfactory use feeling, for example, spreadability on the skin, without giving a rough feeling or be satisfactory spread on a base plate but also to have high hiding power and take on a beautiful color tone. The black brightening flake comprises a metal oxide, as a mother material, which is derived from a colloidal metal oxide particle and 5 to 70% by mass black pigment dispersedly contained in the base material. The black brightening flake has an average particle diameter of 3 to 500 μm, an average thickness of 0.1 to 5 μm, and an average aspect ratio of 5 to 300.
摘要:
A glass article has an indication on its surface. The indication has gloss and high luminance and is capable of providing a variety of color tones. The indication is made of a composition containing a glossy pigment comprising glass flakes coated with metal oxide having a refractive index higher than that of glass and/or a glossy pigment comprising glass flakes coated with metal. The indication is formed by applying a paint containing a glossy pigment comprising glass flakes coated with metal oxide having a refractive index higher than that of glass and/or a glossy pigment comprising glass flakes coated with metal and, after that, heating the paint if necessary. A matte inorganic pigment layer may be provided to cover the indication.
