Title:
PARTICLES, AND SUBSTRATE WITH TRANSPARENT COATING FILM CONTAINING SAID PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/163397
Kind Code:
A1
Abstract:
The present invention provides particles, each of which comprises an antibacterial outer shell containing silicon and a cavity inside the outer shell. Each of the particles contains 0.5% to 40% by mass of an antibacterial metal component in terms of oxides, while having a cavity inside an outer shell that contains silicon. The void fraction of the particles is 10% to 90%; and the proportion of the number of particles that have one cavity is 80% or more relative to all particles. A substrate with a transparent coating film using the particles has sufficient hardness, sufficient strength and high antibacterial activity, and is particularly useful for antireflection.
