  • Patent number: 9238715
    Abstract: An object of the present invention is to provide a polymerizable composition capable of providing antimicrobial properties to ophthalmic and medical devices relatively inexpensively with ease, and an antimicrobial composition obtained by polymerizing the polymerizable composition. A polymerizable composition for ophthalmic or medical use comprising an epsilon-polylysine having (meth)acryloyl group is provided. The content of the epsilon-polylysine having (meth)acryloyl group in the polymerizable composition is preferably about 0.1 to 99% by weight, based on the whole amount of the composition. A coating agent for ophthalmic or medical use comprising the above polymerizable composition, an antimicrobial composition for ophthalmic or medical use obtained by polymerizing the above polymerizable composition, an ophthalmic or medical device comprising the antimicrobial composition, and a contact lens comprising the antimicrobial composition are also provided.
