Title:
INORGANIC OXIDE PARTICLES COATED WITH SILANE COMPOUND HAVING NITROGEN-CONTAINING RING, AND COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/117086
Kind Code:
A1
Abstract:
[Problem] To provide: inorganic oxide particles in which excitation by ultraviolet radiation is almost completely suppressed and which have an extremely small particle diameter at which interference fringe does not occur in a coating film and high transparency can be ensured, even in cases where the particles are applied to a substrate having a high refractive index; a coating composition containing such particles; and an optical member having a cured film formed from the coating composition. [Solution] Provided are: inorganic oxide particles obtained as a result of an organic silicon compound having a nitrogen-containing heterocyclic group being bound to surfaces of modified metal oxide colloid particles (C) that have an average particle diameter of 2-100 nm and that are obtained using metal oxide colloid particles (A) having an average primary particle diameter of 2-60 nm as nuclei, with the nuclei surfaces being coated with a coating comprising inorganic oxide colloid particles (B) having an average primary particle diameter of 1-4 nm; a coating composition containing the inorganic oxide particles; and an optical member having a cured film formed from the composition.
