<p><P>PROBLEM TO BE SOLVED: To provide a new acylphosphine oxide compound capable of imparting high adhesiveness to dentine to a composition, when being combined with a polymerizable monomer to form the composition, and imparting stable adhesiveness having small dispersion between adhesion operations. <P>SOLUTION: This invention relates to a compound represented by general formula (1). (In the general formula (1), R<SP POS="POST">1</SP>-R<SP POS="POST">15</SP>represent each independently a hydrogen atom, a group represented by general formula (2), or a 1C-20C organic group which may have a substituent, and at least one of R<SP POS="POST">1</SP>-R<SP POS="POST">15</SP>is the group represented by the general formula (2)). In the general formula (2), (in the formula, R<SP POS="POST">16</SP>represents a hydrogen atom or a 1-20C organic group which may have a substituent, R<SP POS="POST">17</SP>represents a hydrogen atom or a 1-20C organic group which may have a substituent, and X represents an oxygen atom, a sulfur atom, or -N(R<SP POS="POST">18</SP>)- (R<SP POS="POST">18</SP>represents a hydrogen atom or a 1-20C organic group which may have a substituent)). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
