Document Type and Number:
Japanese Patent JP6962504
Kind Code:
B2
Abstract:
The present invention provides: inorganic fine particle dispersion which contains (A) inorganic fine particles and (B) a dispersant, and which is characterized in that the dispersant (B) contains (b1) a phosphoric acid ester compound having at least one (meth)acryloyl group and at least one polyester chain and (b2) a hydroxyl group-containing compound having a molecular weight of 250 or less; a curable composition; and an optical member. This inorganic fine particle dispersion exhibits excellent dispersion stability and is capable of forming a cured coating film that has high refractive index performance and excellent bleeding resistance.
