Title:
DISPERSION LIQUID OF CHAIN PARTICLES AND METHOD FOR PRODUCING SAME, COATING MATERIAL FOR FORMING COATING FILM, AND METHOD FOR PRODUCING SUBSTRATE WITH FILM
Document Type and Number:
WIPO Patent Application WO/2022/163739
Kind Code:
A1
Abstract:
Provided is a dispersion liquid of chain particles, the dispersion liquid having good dispersion stability even in a low pH region. That is, provided is a dispersion liquid of chain particles which are ATO particles connected to each other, wherein the average particle diameter of the ATO particles is 5-20 nm, the chain particles include silicon oxide, the average number of connected particles of the chain particles is 3-40, and the isoelectric point of the chain particles is less than pH 2.0. This coating material prepared by using such a dispersion liquid of chain particles can form a film which has a low surface resistance value and is excellent in adhesiveness with a substrate even when the content of the particles is low. Furthermore, it is preferable that these chain particles include tin oxide and antimony oxide, and silicon oxide, tin oxide, and antimony oxide are included in amounts of 0.5-10% by weight, 70-95% by weight, and 4.5-29.5% by weight, respectively, relative to the sum of same.
