PROBLEM TO BE SOLVED: To provide a novel trehalose derivative used suitably especially as a polymerizable monomer component of a dental adhesive composition.SOLUTION: The trehalose derivative is represented by general formula (1). (In the formula, m is an integer of 1-8, n is an integer of 0-9, A is a trehalose residue obtained by removing hydroxyl groups to the number of m from trehalose, and each R independently represents a hydrogen atom or a methyl group).COPYRIGHT: (C)2013,JPO&INPIT【課題】特に歯科用接着性組成物の重合性単量体成分として好適に用いられる、新規なトレハロース誘導体を提供する。【解決手段】下記一般式(1);【化1】式中、mは1乃至8の整数、nは0乃至9の整数、Aはトレハロースからm個の水酸基を除いたトレハロース残基、Rは各々独立して水素原子またはメチル基である、で表されるトレハロース誘導体。【選択図】なし
