PROBLEM TO BE SOLVED: To provide a dental adhesive material having a high bonding strength with a teeth material without performing pretreatment, and also capable of easily attaching filling for repairing materials such as a composite resin, etc., with the adhesive material surface.SOLUTION: This dental adhesive material is obtained by blending a soft resin having &le270°K glass transition temperature such as a styrene-butadiene copolymer, an ethylene-vinyl acetate copolymer, a polyaminoamide resin, etc., with the dental adhesive material, more concretely, by blending with a polymerizable composition so as to become as consisting of an acid group-containing polymerizable monomer, a polymerizable monomer, a polymerization initiator, volatile organic solvent and water.COPYRIGHT: (C)2008,JPO&INPIT【課題】 前処理をしなくても歯質に対して高い接着力を有し、且つ、コンポジットレジン等の充填修復材料を接着材面に容易に付着させることができる歯科用接着材を提供する。【解決手段】 ガラス転移温度が270K以下である、スチレン-ブタジエン共重合体、エチレン酢酸ビニル共重合体、ポリアミノアミド樹脂などの軟質樹脂を、歯科用接着材、具体的には、酸性基含有重合性単量体、重合性単量体、重合開始剤、揮発性有機溶媒および水からなるような重合性組成物に配合する。【選択図】 なし
