PROBLEM TO BE SOLVED: To provide a curable composition for medical/dental use as a medical/dental material containing a polycarboxylic acid containing less than 1 mass% of low-boiling compounds including an unpolymerized acrylic acid monomer and methacrylic acid monomer through efficiently and economically removing these compounds.SOLUTION: The curable composition for medical/dental use is, for example, resin-modified glass ionomer cement, which comprises a powder component comprising fluoroaluminosilicate glass powder, a polymerization initiator and a polymerization promoter and a liquid component comprising an acidic polyelectrolyte containing 0.00001-1 mass% of unreacted monomer, purified water, a hydroxycarboxylic acid and a radical-polymerizable monomer. By using these components as a combination capable of being coexistent, the purpose can be attained.COPYRIGHT: (C)2007,JPO&INPIT【課題】医科歯科用材料において、効率的かつ経済的に未重合のアクリル酸モノマーやメタクリル酸モノマー等の低沸点化合物を除去し、該未重合アクリル酸モノマーやメタクリル酸モノマー等の含有率を1質量%以下含有するポリカルボン酸を組成中に含む医科歯科用硬化性組成物の提供。【解決手段】レジンモディファイドグラスアイオノマーセメントにおいて、フルオロアルミノシリケートガラス粉末、重合開始材、重合促進材を含む粉成分と、液成分として未反応モノマー0.00001~1質量%を含む酸性高分子電解質、精製水、ヒドロキシカルボン酸およびラジカル重合性単量体が挙げられ、これらを共存可能な組み合わせで使用することにより目的を達成できる。【選択図】なし
