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.

Claims

51. An antibacterial and deodorizing solution comprising the a silver complex, wherein the lone pair electrons of nitrogen atom of amine compound with high boiling point or water-soluble polymer having basic nitrogen atom in the backbone or side chain are coordinated with silver ion, as effective component.

62. The antibacterial and deodorizing solution according to claim 5, wherein said silver complex is dissolved in water solvent or mixture solvent of water and alcohol.

73. The antibacterial and deodorizing solution according to claim 5, wherein said water-soluble polymer having basic nitrogen atom in the backbone or side chain is selected from the group consisting of polyvinylamine, polyarylamine, polyethyleneimine, polyhexamethylenebiguanidine and polyvinylpyridine.

84. The antibacterial and deodorizing solution according to claim 5, wherein said amine compound with high boiling point is selected from the group consisting of monoethanolamine, diethanolamine and triethanolamine.

95. The antibacterial and deodorizing solution according to claim 5, wherein said silver ion is derived from silver nitrate, silver acetate, silver sulfate, silver benzoate, silver salicylate, silver thiosalicylate or silver sulfadiazine.
