<p>A resinous composition for dental use is provided, of which the cured product is neither stained nor discolored while used in the mouth for a long period of time. In addition, the cured product of the composition is not discolored with hot water, and its impact strength is high. The composition is easy to handle, and its storage stability is good. The composition comprises (a) impact-resistant resinous complex composed of core-shell structured polymer particles having at least one hard polymer layer, at least one soft polymer layer and an outermost hard polymer layer and (meth)acrylic polymer, and containing ionic components in total amount of not larger than 0.05% by weight, (b) (meth)acrylate monomer, and (c) polymerization initiator.</p> |
