<p>A method for forming a protective film (16) that protects the surface of a mold (10) that has a fine textured pattern (P) on said surface. In said method, a coating is prepared by mixing the following: an isocyanate-group-terminated prepolymer (liquid A) obtained by mixing and reacting an organic isocyanate with an active-hydrogen-containing compound, the ratio (NCO/H) of the number of moles of isocyanate groups (NCO groups) in the organic isocyanate to the number of moles of active hydrogen (H) in the active-hydrogen-containing compound being between 5.5:1 and 20:1; and a resin (liquid B) obtained by mixing an aromatic diamine, a polyol and/or a polyetheramine, and a curing catalyst. Said coating is applied to the abovementioned surface having a textured pattern (P), and the applied coating is dried, forming a protective film (16) on said surface.</p> |
