Hydrophilic film, hydrophilic film-coated article, hydrophilic film-forming coating liquid, and method for producing hydrophilic film

摘要

PROBLEM TO BE SOLVED: To provide a hydrophilic film, a hydrophilic coated article, a coating liquid for forming a hydrophilic film and a method for producing a hydrophilic film that can stabilize not only a silicon oxide (SiO) component but also a zirconium oxide (ZrO) component and can easily form a film without precipitation and gelation by instantaneously reacting the silicon oxide (SiO) component and the zirconium oxide (ZrO) component even when those two components simultaneously coexist.SOLUTION: The hydrophilic film is composed of (formula 1): (Li)(Na)(K)(NH)(CO)(SiO)(ZrO)m(HO) (provided that a+b+c+d0; x0; y0; z0; and m is an optional number).
