Disclosed is a composition which exhibits excellent adhesion to tooth structure (especially to dentin) when applied to a dental material. Specifically disclosed is a composition containing a polymerizable monomer (A) having an unconjugated carbon chain wherein four or more carbon atoms are continuously bonded, two or more polymerizable groups and two or more hydroxy groups, and a bisacylphosphine oxide (B) represented by the following formula (1).
