摘要： Provided are adhesive monomers for dental materials including compounds represented by the general formula (1) below, in which the core (X) and the terminal group (Y1) are bonded to each other directly or via the linking group (Z): X(Y1)n1a(Z—Y1)n1b(1) wherein n1a represents the number of terminal groups (Y1) directly bonded to the core (X), n1b represents the number of terminal groups (Y1) bonded to the core (X) via the linking group (Z), and the sum of n1a and n1b is equal to the valence of the core (X); the core (X), the linking group (Z) and the terminal group (Y1) are further defined. The adhesive monomers can enhance adhesive strength to the tooth in dental treatment, and impart high mechanical strength to cured products.
