Title:
DISPERSION LIQUID, METHOD FOR PRODUCING SAME, AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/243652
Kind Code:
A1
Abstract:
Provided is a dispersion liquid containing titanium oxide particles, a silane coupling agent and a monomer having a polymerizable functional group. The titanium oxide particles are particles obtained by surface treating a core of rutile titanium oxide with a hydrous oxide of tin or zirconium. The viscosity of the monomer at 25°C is 100 mPa·s or less. After the dispersion liquid is strongly heated for 2 hours at 925°C, the solid content amount is 15-55 mass%. In the dispersion liquid, the content of the silane coupling agent is 2-15 mass%, the content of the monomer is 30-85 mass%, and the content of organic solvents having no polymerizable functional group is 10 mass% or less. The viscosity of the dispersion liquid at 25°C is 500 mPa·s or less. Due to this configuration, provided is a curable dispersion liquid which contains titanium oxide particles, which has a high refractive index, which exhibits excellent transparency, which has a low content of volatile solvents, which has a low viscosity, and which exhibits excellent viscosity stability.
