Title:

SILICON-DOPED METAL OXIDE PARTICLES, AND UV-ABSORBING COMPOSITION CONTAINING SILICON-DOPED METAL OXIDE PARTICLES

Document Type and Number:

WIPO Patent Application WO/2018/150477

Kind Code:

A1

Abstract:

The present invention is intended to provide UV-absorbing silicon-doped metal oxide particles having an increased average molar attenuation coefficient in a wavelength range of 200 nm to 380 nm. The present invention provides silicon-doped metal oxide particles obtained by doping metal oxide particles with silicon, wherein the silicon-doped metal oxide particles are characterized in that a liquid dispersion obtained by dispersing the silicon-doped metal oxide particles in a dispersion medium has a better average molar attenuation coefficient in a wavelength range of 200 nm to 380 nm than when non-silicon-doped metal oxide particles of the same species are used.
