Hydrophilic film-forming article, coating solution for forming hydrophilic film and method for producing hydrophilic film-formed article

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic coating-formed article excellent in anti-fouling capability that is difficult to be adsorbed by cationic surfactant or the like.SOLUTION: Provided is a hydrophilic coating-formed article comprising a substrate and a coating that is formed by dispersing oxide fine particles on the surface of the substrate and held there by a metal oxide layer. The metal oxide layer comprises at least one of silicon oxides represented by the following general formula [1] and at least one of aluminum oxides represented by the following general formula [2], and the mole ratio of the silicon oxide and the aluminum oxide is silicon oxide:aluminum oxide=20:80 to 80:20. (R)SiO[1] (In the formula [1], Ris a monovalent organic group, a is 0 to 3.5, and b is 0.5 to 2.). (R)AlO[2] (In the formula [2], Ris at least one group selected from acetylacetonato group and ethyl acetoacetate group, c is 0 to 2, and d is 0.5 to 1.5.).
