Claim Text:
1. A method for producing a replica mold comprising the steps of: (A) coating a surface of a substrate with an organic-inorganic hybrid material to form an organic-inorganic hybrid material layer; (B) semi-curing the organic-inorganic hybrid material layer with heat and/or an electromagnetic ray to produce a semi-cured organic-inorganic hybrid material layer; (C) pressing a master mold having a predetermined fine raised and depressed pattern formed thereon directly against an exposed surface of the semi-cured organic-inorganic hybrid material layer by an imprinting method to transfer the fine raised and depressed pattern onto the exposed surface of the semi-cured organic-inorganic hybrid material layer; and (D) irradiating the semi-cured organic-inorganic hybrid material layer onto which the fine raised and depressed pattern is transferred with an electromagnetic ray to cure the semi-cured organic-inorganic hybrid material layer, wherein the organic-inorganic hybrid material comprises: a) an organosilicon compound comprising: a compound represented by the formula (I): (wherein n represents 1 or 2; when n is 2, each R a compound represented by the formula (II): (wherein n represents 1 or 2; when n is 2, each R a hydrolysis condensate thereof if present, wherein {[the compound of the formula (I)]+[a unit derived from the compound of the formula (I) in the hydrolysis condensate if present]}/{[the compound of the formula (I)]+[the compound of the formula (II)]+[a unit derived from the compound of the formula (I) in the hydrolysis condensate if present]+[a unit derived from the compound of the formula (II) in the hydrolysis condensate if present]}×100 is 30 to 100 mol %; and {[the compound of the formula (II)]+[a unit derived from the compound of the formula (II) in the hydrolysis condensate if present]}/{[the compound of the formula (I)]+[the compound of the formula (II)]+[a unit derived from the compound of the formula (I) in the hydrolysis condensate if present]+[a unit derived from the compound of the formula (II) in the hydrolysis condensate if present]}×100 is 0 to 70 mol %; b) an electromagnetic ray-curable compound; and c) a silanol condensation catalyst.
