Definitions
- the present invention relates to a method for designing a light interference multilayer film-coated powder, a production method, and a light interference multilayer film-coated powder, and more particularly, to a light interference multilayer film-coated powder having weather resistance and a vivid desired color.
- the present invention relates to a body design method, a manufacturing method, and a powder coated with a light coherent multilayer film.
- Background Art By coating the surface of a powder with a film of another substance, it is known to improve the properties of the powder and impart diversity to the properties.
- powders with these In particular, there is a demand for a powder having a combination of functions in addition to the properties provided only by metal powders or metal compound powders. In order to manufacture these powders, it was conceivable to provide a plurality of metal oxide films or the like having a uniform thickness on the base particles.
- the present inventors have previously proposed a method of forming a metal film on substrate particles and whitening the powder by the reflection effect of the film (Japanese Patent Application Laid-Open Nos. 3-271713, No. 3,274,278), by dispersing the base particles in a metal alkoxide solution and hydrolyzing the metal alkoxide to form a uniform 0.01 to 20 on the surface of the base particles.
- Invented a method of forming a metal oxide film having a thickness of 1/1 m and producing a powder having a metal oxide film containing a metal different from the metal constituting the base as a component (Japanese Patent Application Laid-Open No. H06-208). No. 2,286,004).
- the powders provided with a plurality of metal oxide films or metal films described above can be provided with a special function by adjusting the film thickness of each layer. If a coating film having a different refractive index is provided on the surface of each particle at a thickness corresponding to a quarter wavelength of the incident light, a powder that reflects all the incident light can be obtained. When this is applied to a material using a magnetic substance as base particles, light can be reflected to produce a white toner powder. Unit cover By setting the number of multilayer thin films and the refractive index and film thickness of each film so that the covering layer has a specific interference reflection peak of the same wavelength, a monochromatic color can be obtained without using a dye or pigment. It was shown that it can be made into powder.
- the coating control of the multilayer thin film is performed by fitting the measured value of the spectral reflection curve after each layer coating to the design value. This control can be precisely performed using the plane wave solution of the electromagnetic equation of MaxWe 11 as a design value, especially when the base material is a flat plate.
- ⁇ th layer when the light of the incident light wavelength ⁇ is incident on the N-layered multilayer film at an incident angle ⁇ ⁇ + 1 , nj and dj are changed to the j-th layer from the bottom (hereinafter referred to as the ⁇ th layer).
- rj + is the Fresnel reflection coefficient of the interface between the (j + 1) th and jth layers, and for P-polarized light (the component parallel to the plane of incidence of the electric field),
- the maximum or minimum reflection wavelength of each coating film measured by a spectrophotometer is a desired value considered when the substrate is a flat body.
- the film is formed in this manner, there is also a problem that the finally obtained multilayer-coated powder does not have a desired reflection intensity at a desired wavelength.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2000-201710
- Patent Document 1 aims at only that the reflection peak or the bottom of the spectral photometric waveform is located in a wavelength region corresponding to a desired color, and that the reflectance is maximum or minimum. It is that. Therefore, the spectral photometric waveform of the powder having the coating structure designed by the technology described in Patent Document 1 did not always match the spectral photometric waveform of the desired color. Therefore, it has been necessary to perform color matching and toning using other pigments or the like so that the desired color can be obtained.
- the conventional organic pigment has a problem that, although the color is vivid, the weather resistance is poor and the color fades. Also, simply matching only the reflection peak or the bottom has a problem that an unnatural light interference color such as an iridescent color with a strong light is generated.
