Abstract
An antibacterial agent includes a block isocyanate. The block isocyanate includes a capped residue (A) of a polyisocyanate, an antibacterial-non-block capping group (B), and a non-antibacterial-block capping group (C). The capped residue (A) of the polyisocyanate is formed by capping an isocyanate group of the polyisocyanate having a plurality of isocyanate groups. The antibacterial-non-block capping group (B) is formed by non-reproducibly capping at least a portion of the plurality of isocyanate groups. The non-antibacterial-block capping group (C) is formed by reproducibly capping at least a portion of the plurality of isocyanate groups. The antibacterial-non-block capping group (B) includes a quaternary ammonium group.
