An antimicrobial polymerizable composition comprising an ethylenically unsaturated monomer, a specific monomer having antimicrobial activity and a polymerization initiator. The composition gives, upon polymerization, a polymer having permanent antimicrobial property, which is very useful for medical articles, in particular dental materials.
