Abstract
The present invention relates to novel antibacterial agents wherein the lone pair electrons of nitrogen atoms of amine compounds with high boiling point or water-soluble polymer with basic nitrogen at the backbone or side chain are coordinated with silver ion, and antibacterial and deodorizing solution comprising them. Since the antibacterial agents of the present invention has silver (Ag) ion coordinated with the lone pair electrons of nitrogen atom, the problems of conventional silver (Ag) compounds, i.e., their ease discoloration in general waters such as tap water and industrial water, are solved, and the inherent antibacterial activity is maintained due to the stabilization of silver ion (Ag+). Also, since they are highly soluble in water, they can be prepared in liquid form to be used for antibacterial and deodorizing purposes.
