(57) [Summary] [Structure] (a) Specific aminoalkylalkoxysilane compound (eg, γ-aminopropyltriethoxysilane), (b) Specific amount of metal oxide sol (eg, silica sol), (c) Water, (d) organic solvent, (e) acid and (f) A coating composition comprising functional fine particles (eg, fluororesin fine particles) and having a pH of 6.5 to 8.0. [Effects] When this coating composition is applied to a substrate and cured, a coating film having no variation and not impairing the transparency of the substrate and having excellent scratch resistance can be formed. Also, depending on the function of the functional fine particles, abrasion resistance, water repellency, The film can be provided with functions such as antifouling property, weather resistance, conductivity, ultraviolet absorption and antibacterial property. |
