Abstract
There are provide a liquid composition for forming a silicon oxide-based cured coating film by the sol-gel method, the liquid composition having excellent storage stability and being capable of forming a coating film excellent in durability, in particular, alkali resistance even after long-term storage. A liquid composition applied on a surface of a substrate and cured by heating to form a coating film, contains: a matrix component containing a hydrolyzable silicon compound whose content is 20 to 60 mass % as a SiOcontent when silicon atoms contained in the matrix component are converted into SiOto the total solid content amount in the liquid composition; a functional component containing an ultraviolet absorbent and an infrared absorbent; water; and an acid thermally decomposing at 80° C. or higher and a temperature of the heating or lower, wherein a pH increases between before and after the thermal decomposition of the acid.
