Abstract:
A precursor sol of aluminum oxide includes a solvent and particles containing a hydrolysate of an aluminum compound and/or a condensate of the hydrolysate, in which the particles have an average particle size of 2.5 nm to 7 nm. A method for producing an optical member includes the steps of feeding the precursor sol of aluminum oxide described above onto a base to form an aluminum oxide film and immersing the aluminum oxide film in hot water with a temperature of 60° C. to 100° C. to form a textured structure comprising aluminum oxide boehmite.
