<p>PURPOSE:To provide the above composition composed of a photo-polymerizable compound having ethylenic unsaturated double bond, an organic filler and a reducing agent, having high compatibility to a working model, moderately bonding with the model and easily removable after curing. CONSTITUTION:The objective photo-polymerizable resin composition for production of a clasp pattern is composed of (A) 100pts.wt. of a photo-polymerizable compound having at least one ethylenic unsaturated double bond (especially preferably methacrylate of acrylate which is solid at normal temperature), (B) an organic filler (e.g., polyolefin powder or polyacrylate powder in an amount of preferably 0.1-90pts.wt.), (C) a photo-polymerization initiator (especially an alpha-diketone compound, etc., in an amount of preferably 0.001-5pts.wt.) and (D) a reducing agent (e.g., triethanolamine in an amount of preferably 0.01-10 pts.wt.). It can be used advantageously in the production of a partial denture.</p> |
