A photo-curable resin composition containing a polycarbonate having a number average molecular weight of between 200 and 10,000 and containing at least two (meth)acrylate groups in the molecule, or a diglycidyl phthalate (meth)acrylate, an organic polymer fine powder having an average particle diameter of between 1 µm and 50 µm and a photo-radical polymerization initiator; and a coating liquid to be applied to a resin pattern. This resin composition is useful for preparing a clasp pattern exhibiting a theoretical form for retention, durability, etc., i.e., a cast clasp basic pattern, for producing, by a lost wax method, a cast clasp which is a metal component for holding a partial denture, retaining it and supporting it. |
