Resinous composition capable of releasing a bioactive substance at a controlled rate.

摘要

A bioactive substance control-releasing resinous composition comprising a resin having main chain and side chains, at least one side chain bearing at the end portion thereof an organic acid moiety having a biological activity through a metal ester bonding. The resin is hydrolyzed in an ionic atmosphere at a controlled rate to generate a bioactive substance as well as metal ions and is useful in various field and especially as resinous vehicle of coating composition.
