Title:
DISPERSION OF TITANIUM DIOXIDE MICROPARTICLES IN ORGANIC SOLVENT, METHOD FOR PRODUCING SAME, AND USE OF SAME
Document Type and Number:
WIPO Patent Application WO/2021/106747
Kind Code:
A1
Abstract:
Provided are: a dispersion in which titanium dioxide microparticles are highly dispersed in an organic solvent; and a method for producing the dispersion. The dispersion comprises at least titanium dioxide microparticles, an organic solvent, a silane coupling agent, and a dispersant having a basic adsorptive group, wherein the ratio of the mass of the dispersant to that of the silane coupling agent is 15 to 75% by mass. It is preferred that the ratio of the total mass of the silane coupling agent and the dispersant to the mass of the titanium dioxide microparticles is 10 to 40% by mass. The dispersion is produced by dispersing the titanium dioxide microparticles together with the above-specified amounts of the silane coupling agent and the dispersant having a basic adsorptive group in the organic solvent.
