Title: Article coated with antireflection film and method for producing the same
Inventor: SAITO YASUHIRO
IPC: G02B1/11
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To profitably coat a substrate with an antireflection film which reduces the reflectance of the surface of the substrate even when the substrate is made of a resin or the like having inferior heat resistance because the antireflection film is different from a conventional antireflection film formed by laminating high and low refractive index layers by a method such as vapor deposition which requires an expensive vapor deposition equipment, the strict control of thickness accuracy of plural layers and the heating of a substrate. SOLUTION: A 1st treating solution prepared as an ammonium titanofluoride- containing supersaturated solution of titanium oxide and a 2nd treating solution prepared as an ammonium silicofluoride-containing supersaturated solution of silicon dioxide are mixed in an appropriate ratio and a composition gradient is imparted to a film in the thickness direction by utilizing the difference in deposition rate between titanium in the 1st treating solution and silicon in the 2nd treating solution. The difference in deposition rate is produced by adding an EDTA chelating agent which selectively forms a chelate compound with titanium to the mixed treating solution. The thickness of the resulting antireflection film is preferably 20-150 nm.
