Abstract
A film or sheet material having antibacterial and antifungal activities is obtained by mixing a thermoplastic resin with 2-(4'-thiazolyl)-benzimidazole and N-(fluorodichloromethylthio)-phthalimide, and shaping the resulting mixture, or, alternatively, by coating a base film or sheet material on one side or both sides with a coating material containing a mixture of 2-(4'-thiazolyl)-benzimidazole and N-(fluorodichloromethylthio)-phthalimide, a mixture of 2-(4'-thiazolyl)-benzimidazole and N-dimethyl-N'-phenyl-N'-(fluorodichloromethylthio)-sulfamide, or a mixture of N-(fluorodichloromethylthio)-phthalimide and N-dimethyl-N'-phenyl-N'-(fluorodichloromethylthio)-sulfamide.
