Abstract

본 발명은 하기 구조식(Ⅱa)의 3관능성 메타크릴산 에스테르 및 그의 이성체로 이루어진 치과 수복 재료용 광경화성 수지 프리폴리머 및 그를 제조하는 벙법에 관한 것이다. 본 발명은 또한 상기 프리폴리머, 광개시제시스템 및 무기 충전제 등을 함유하는 치과용 수복 재료로 사용되는 광경과성 복합 수지 조성물에 관한 것으로 본 발명의 조성물로부터 제조된 광경화물은 감소된 수분 흡수성으로 인해 종래의 수복 재료보다 우수한 물리적 특성 및 심미성을 갖는다.The present invention relates to a photocurable resin prepolymer for dental restorative materials consisting of a trifunctional methacrylic acid ester of the following structural formula (IIa) and an isomer thereof, and a process for producing the same. The present invention also relates to a photopermeable composite resin composition used as a dental restorative material containing the prepolymer, photoinitiator system, inorganic filler and the like, wherein the photocured resin prepared from the composition of the present invention It has better physical properties and aesthetics than the restorative material.
