Abstract
This invention relates to an ionic antimicrobial coating. Such a coating may contain (1) a water-insoluble polymer having a first ionized group and (2) an antimicrobial agent having a second ionized group with a charge opposite to that of the first ionized group, in which the antimicrobial agent is attached to the water-insoluble polymer via an ionic bond between the first ionized group and the second ionized group.
