ANTI-REFLECTION FILM-FORMING COMPOSITION AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To form an anti-reflection film for preventing reflection of light rays irradiated from an eternal light source while maintaining light transmittance of a transparent conductive film or the like on which the anti-reflection film is formed.SOLUTION: An anti-reflection film-forming composition is coated on a transparent conductive film, glass, or light transmissive plastic having a refractive index in a range of 1.6-2.0 at a wavelength of 550 nm to form an anti-reflection film having a lower refractive index. The anti-reflection film-forming composition contains a hydrolysate of a metal alkoxide, and phosphoric acid. Defining A (mol/L) as molar concentration of metal of the metal alkoxide and B (mol/L) as molar concentration of the phosphoric acid, B/A shall be in a range of 0.002 to 0.1.
