Title:
LIQUID DISPERSION OF PARTICLES EACH HAVING SHELL CONTAINING FUNCTIONAL GROUP AND SILICON AND VOID IN SAID SHELL, AND METHOD FOR PRODUCING SAID LIQUID DISPERSION
Document Type and Number:
WIPO Patent Application WO/2023/090135
Kind Code:
A1
Abstract:
Provided is a liquid dispersion of particles each having a silicon-containing shell and a void formed in the shell, in which an organosilicon compound is precisely carried on the surfaces of the particles and the dispersibility of the particles in a dispersion medium or a resin is high. Each of the particles contains a functional group and silicon. The average value of diameters of primary particles which is determined by the analysis of an image of the particles is 20 to 250 nm, and the carbon content in the particles is 0.5 to 10% by mass. The amount of the organosilicon compound contained in a liquid produced by removing the particles from the liquid dispersion containing the particles is 0.50 part by mass or less in terms of solid content relative to 100 parts by mass of the particles. According to the liquid dispersion, it is possible to produce a coating solution that enables the production of a coating film having a low reflectance, excellent adhesion to a base material, high hardness and high strength.
