For example, in the case of titanized mica, this pigment is obtained by forming a metal plating layer scattered in an island shape on the surface of an interference layer made of titanium dioxide. The present inventors have conducted intensive studies on this pigment with reference to the above-described conventional technology. As a result, the inventors have found that when the metal particles of the metal plating layer have a small particle size and are colloidal, when the surface of the metal plating layer is further coated with titanium dioxide, the present invention has been found to exhibit extremely strong color development. It is.

An interference layer, colloidal metal particles scattered in islands on the surface of the first interference layer, and a second interference layer made of titanium dioxide and coated on the surfaces of the first interference layer and the colloidal metal particles. The color is formed by interference light from the first interference layer and the second interference layer and light scattered by the colloidal metal particles.

あり、一辺の長さが３〜50μｍのものが最適である。As the substrate, a scaly ceramic material is used, and examples thereof include natural or synthetic mica such as white mica and black mica, and molybdenum disulfide. This base material is in the form of a scale with an average thickness of about 500 to 1000 mm, and the length of one side is preferably 3 to 50 μm.

種々変化する。The first interference layer and the second interference layer are made of titanium dioxide, and the first interference layer is usually coated on the entire surface of the substrate. The thickness of the first interference layer and the thickness of the second interference layer are configured such that the sum of the respective values is a value that emits interference light. Usually, the range of 10 to 200 nm is sufficient, and even if the thickness is 200 nm or more, the effect is saturated. The color tone of the interference light changes variously depending on the thickness.

が好ましい。そして第１表（「化学大辞典」第923頁、
共立出版（株）発行）に示すように、粒径により散乱光
の色調が変化することがわかっている。The most significant feature of the present invention resides in a configuration in which colloidal metal particles are interposed between the first interference layer and the second interference layer. That is, the first interference layer and the second interference layer function as a dispersion medium, and the colloidal metal particles function as dispersoids, so that the colloidal metal particles emit scattered light. Therefore, the particle size of the colloidal metal particles greatly affects color development, for example, 1 nm to 500 nm in the case of silver.
Is preferred. And Table 1 ("Chemical Encyclopedia", page 923,
As shown in Kyoritsu Shuppan Co., Ltd.), it is known that the color tone of the scattered light changes depending on the particle diameter.

ぎると散乱光が少なくなり、意匠性が低下する。Colloidal metal particles form islands on the surface of the first interference layer Dotted. The distance between each particle is not as important as the particle size, but in the case of silver, 10 nm to 200 nm contributes to light scattering. If the distance between the particles is too small, light scattering hardly occurs, and the color of the metal is undesirably revealed. On the other hand, if it is too large, the amount of scattered light is reduced, and the design is reduced.

Is determined by Therefore, if the interference color and the scattered color are configured to have the same color tone, the appearance color and the interference color match, and a strong color is obtained.

ばよい。To produce the pigment of the present invention, first, a first interference layer made of titanium dioxide by a known method such as a titanyl sulfate method described in JP-B-43-25644 or the like, on a flaky substrate surface such as mica. Form. Next, colloidal metal particles are scattered in an island shape on the surface of the first interference layer from a metal such as silver by an electroless plating method or the like. At this time, the particle diameter and the distance between the metal particles can be easily controlled by the ratio of the weight of the generated metal particles to the weight of the base material. For example, when the base material is mica and the metal particles are silver, the metal particles may be formed so that the total weight of the silver particles is 1 to 20% by weight of the weight of the mica.
そして第１干渉層とコロイド状金属粒子をもつ基材表

Are scattered like islands. That is, a solid colloid in which metal particles are dispersed as a dispersoid in a titanium dioxide dispersion medium having a high refractive index is formed. Therefore, when light enters from the surface of the second interference layer, light scattering occurs in the metal particles due to the Tyndall phenomenon. On the other hand, although light absorption is also caused by the metal particles, the wavelength dependence of the absorption differs depending on the particle diameter, and thus the extra color seen from the outside also differs depending on the particle diameter of the metal particles. That is, various scattered lights are colored depending on the particle size of the metal particles.
また、二酸化チタンは屈折率が高いため、第２干渉層

干渉層の界面などで反射することにより、干渉が生じ

厚に応じた色調の干渉色が見える。Further, since titanium dioxide has a high refractive index, light incident from the surface of the second interference layer is not reflected on the interface between the first interference layer and the substrate.
Reflection at the interface of the interference layer causes interference. Therefore, an interference color having a color tone corresponding to the thickness of the first interference layer and the second interference layer can be seen from the outside.
すなわち本発明の顔料によれば、金属粒子の光散乱に
よる発色と第１干渉層および第２干渉層の干渉光による
発色とが見え、従来にない意匠の発色が得られる。That is, according to the pigment of the present invention, the coloring by the light scattering of the metal particles and the coloring by the interference light of the first interference layer and the second interference layer can be seen, and the coloring of the design which has not existed conventionally can be obtained.
また金属粒子の粒径や干渉層の膜厚を変更するだけで
種々の色調とすることができるため、特に便利である。
そして明度、彩度などの色調に優れ、かつ安全性、耐候
性、耐薬品性などの諸性能に優れることはその構成から
も明らかである。In addition, various colors can be obtained only by changing the particle size of the metal particles and the thickness of the interference layer, which is particularly convenient.
It is clear from the configuration that the composition is excellent in color tone such as lightness and chroma and excellent in various properties such as safety, weather resistance and chemical resistance.
