At present, many antimicrobe relation goods are being put on sale. Many these products have got the effect by adding the antibacterial agent to plastics, etc. However, it was difficult to uniformly apply the antibacterial agent to wholes such as parts of the complicated shape. We tried preparing antibacterial polyimide films by vapor deposition polymerization of 3, 5-diamino benzoic acid (DBA) and anhydrous pyromellitic acid (PMDA) with the structure of benzoic acid on antibacterial agent. The antimicrobe performance of polyimide film which produced the antimicrobe test was evaluated using film contact printing (JIS Z 2801). The antibacterial polyimide showed antibacterial effects for Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pneumonia bacillus, Pseudomonas aeruginosa, and MRSA.
