Antireflection solution for optical parts and method of antireflection treatment using said solution

Abstract From the Canadian patent

This invention is directed to an antireflection solution having as a main film-forming component thereof a hydrlytic derivative of a silicic ester and to a method for the treatment with the antireflection solution. The antireflection solution and the method for the treatment therewith are characterized by the fact that the hydrolytic derivative of silicic ester is obtained by causing a mixture consisting of the silicic ester and hydrolyzing water added thereto in an amount exceeding the chemical equivalent relative to the silicic ester to be hydrolyzed in the presence of a solvent compatible with both of the components of the mixture and further subjecting the resultant hydrolyzate to …
