The present invention provides a dispersion of chain particles having good dispersion stability even in a low pH region. That is, it is a dispersion liquid of chain-shaped particles connected by ATO particles, the average particle diameter of ATO particles is 5nm~20nm, the chain-shaped particles contain silicon oxide, the average connection number of chain-shaped particles is 3-40, and the The isoelectric point is less than pH2.0. According to the coating material prepared using such a dispersion liquid of chain-shaped particles, even if the content of the particles is small, a film having a low surface resistance value and excellent adhesion to a substrate can be formed.n In addition, the chain-like particles contain tin oxide and antimony oxide, and preferably contain 0.5% to 10% by weight of silicon oxide, 70% to 95% by weight of tin oxide, and 4.5% to 29.5% by weight of antimony oxide based on the sum of these particles. . |
