发明名称 FILM-COATED POWDER, COATING COMPOSITION AND COATED ARTICLE
摘要 <p>PROBLEM TO BE SOLVED: To provide film-coated powder which has a high lightness, a color shift effect exhibiting a strong angle-dependent color change between interference colors, advantageous application characteristics, and an expanded colorability range, to provide a coating composition, and to provide a coated article. SOLUTION: This film-coated powder having coating films on the surfaces of substrate particles, characterized by having a spectrophotometric characteristic that the (H/W) ratio of the height (H) of a peak to the half width (W) is 0.5 to 5, when 400 nm width (wavelength specified width L) in the range of 380 to 780 nm in a reflection spectrum and the height (reflectance specified width R) of vertical axis refection are indicated in a ratio of 5 to 2 on the measurement of the vertical reflection of the film-coated powder.</p>
