Title:
無機微粒子分散体、硬化性組成物及び光学部材
Document Type and Number:
Japanese Patent JP7322710
Kind Code:
B2
Abstract:
The present invention provides: an inorganic microparticle dispersion comprising inorganic microparticles (A) and a dispersant (B), characterized in that the dispersant (B) is a phosphoric acid ester having at least one (meth)acryloyl group and at least one polyester chain; a curable composition containing the inorganic microparticle dispersion; a cured product; and an optical member. This inorganic microparticle dispersion has excellent dispersion stability, and the curable composition containing the inorganic microparticle dispersion can form a cured coating film that has high refractive index performance and excellent resistance to bleed out at low viscosity.
