ZIRCONIA PARTICLE DISPERSION LIQUID, ITS MANUFACTURING METHOD AND PHOTOCURABLE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a zirconia particle dispersion liquid with small dispersion particle diameter and its manufacturing method and to provide a zirconia particle dispersion liquid capable of forming a membrane with high transparency, its manufacturing method and a photocurable composition.

SOLUTION: The zirconia particle dispersion liquid contains a zirconia particle having loss on ignition of 0.1-3%; a dispersing agent; a dispersion auxiliary; and a dispersion medium. The photocurable composition containing the zirconia particle dispersion liquid, a multi-functional (meth)acrylate monomer and a photo-initiator is suitably used as a resin composition for forming a high refractive index membrane of a reflection prevention membrane.
