Paint color material, production method for paint color material, and production method for coating material

Abstract

A method for producing a paint color material developing a color by a pigmentary color and a structural color, the method including: obtaining a mixed liquid containing a color material particles by alternately adding and mixing a liquid obtained by suspending core particles each having a uniform particle diameter in a solution containing Fe and a liquid containing tannic acid into a liquid containing water as a main component, the color material particles each comprising a core portion formed by the core particle and a pigmentary layer that is formed around the core portion and contains an iron tannate, and each having a particle diameter corresponding to a wavelength of the structural color; and washing the color material particles, in which a pH of the mixed liquid is adjusted to 7.0 or more prior to the second step, and the pH is adjusted in order to obtain any color
