Abstract
The present invention relates to a novel diisocyanate-based radical polymerizable silane coupling compound having an urethane bond and a medical and/or dental curable composition comprising the same. The present invention provides a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition.
