PROBLEM TO BE SOLVED: To provide a color-developing flake material and a method for producing the material, which has a periodical structure of fine particles, induces structural color development by diffraction and interference of light incident to the structure, has high joining force among the inorganic fine particles, and exhibits stable color development although the material is not a film formed on a substrate but being a flake material. SOLUTION: The color-developing flake material comprises spherical inorganic fine particles showing a monodispersion distribution of particle diameters and having a closest packed structure. In the structure, adjoining inorganic fine particles are joined through contact points between the inorganic fine particles and include a gap between the particles. The color-developing flake material exhibits structural color development by diffraction and interference of light incident to the structure. COPYRIGHT: (C)2011,JPO&INPIT
