Title:
OXIDE PARTICLES WITH CONTROLLED COLOR CHARACTERISTICS, AND COATING COMPOSITION OR FILM-LIKE COMPOSITION CONTAINING SAID OXIDE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2017/209305
Kind Code:
A1
Abstract:
In order to provide oxide particles with controlled color characteristics, the present invention provides a manufacturing method for oxide particles, which is characterized in that color characteristics of the oxide particles are controlled by controlling the M-OH bond / M-O bond ratio, which is the ratio of M-OH bonds that are bonds between M and oxygen (O), to M-O bonds that are bonds between M and a hydroxyl group (OH), where M is oxygen or one or multiple different elements other than hydrogen contained in oxide particles selected from metal oxide particles and metalloid oxide particles. With the present invention, it is possible to provide oxide particles in which color characteristics such as reflectance, transmittance, molar extinction coefficient, hue or saturation are controlled by controlling the M-OH bond / M-O bond ratio of the metal oxide particles or metalloid oxide particles.
