ABSTRACT:
The present invention provides a primer composition comprising (i) 0.5-90% by weight of water, (ii) 5-90% by weight of a polymerizable compound having hydroxyl group, (iii) 0.1-90% by weight of a polymerizable compound having acidic group, and (iv) 0.01-30% by weight of a curing agent. When dental adhesive restorative materials such as dental resin cements, composite resins, PMMA resins and the like are made to adhere directly or through bonding agents to substrates such as vital hard tissues, especially an enamel or a dentin of natural teeth, glass ionomer cements and the like, the primer composition is able to impart a strong and durable adhesive property between the both without treating said substrates with an acid and the like.
