(57) [Summary] [Constitution] The pH is 10.0 to 1 with respect to 1 mol of a specific tetraalkoxysilane (eg, tetraethoxysilane). The pH of the condensation composition (A) obtained by mixing 2 to 8 mol of basic water of 2.0 and 10 to 30 mol of an organic solvent and 1 mol of a specific alkoxysilane (eg, tetraethoxysilane). With a condensation composition (B) obtained by mixing 3 to 8 mol of acidic water having a ratio of 0 to 2.6 and 10 to 30 mol of an organic solvent, (A) / (B) = 0.4 to 2. 4 (weight ratio) to obtain a solid content concentration of 1.0 to 4.0% by weight of inorganic composition. [Effect] To provide an inorganic composition having excellent storage stability, which is suitable for easily producing a laminate having a porous film having excellent scratch resistance and high antireflection effect formed on a substrate. |
