To provide a polymerizable composition capable of imparting antibacterial properties to ophthalmic devices and medical devices easily at relatively low cost, and an antibacterial composition obtained by polymerizing the same. An ophthalmic or medical polymerizable composition comprising ε-polylysine having a (meth) acryloyl group is provided. In this polymerizable composition, the content of ε-polylysine having a (meth) acryloyl group is preferably about 0.1 to 99% by weight based on the total amount of the composition. Also, an ophthalmic or medical coating agent comprising the polymerizable composition, an ophthalmic or medical antibacterial composition obtained by polymerizing the polymerizable composition, and the antibacterial composition. There are also provided an ophthalmic device or medical device, and a contact lens comprising the antibacterial composition. [Selection figure] None |
