| 摘要 |
The present invention is a polymerization initiator paste composition which comprises (A) an organoboron compound which is liquid at 25 DEG C and (B) particles having an average particle diameter of 0.001 to 50 mu m and inert to the organoboron compound (A), in an amount of 4 to 400 parts by weight based on 100 parts by weight of the organoboron compound (A), and has a consistency, as measured at 25 DEG C under a load of 300 g in accordance with a method defined in ISO4823, of 15 to 100 mm. This composition constitutes a dental kit or the like together with a polymerizable monomer separately packaged. According to the present invention, an organoboron compound can be used safely, and because the composition is a paste, it is very easily utilized.
