- 13. The product of claim 1, wherein:
- said antimicrobial agent is n-trichloromethylthio-4-cyclohexene-1,2-dicarboximide.
- 14. The product of claim 1, wherein:
- said antimicrobial agent is n-trichloromethylthio phthalimide.
- 15. The product of claim 1, wherein:
- said antimicrobial agent is 2,4-dichlorobenzyl alcohol.
- 16. The product of claim 1, wherein:
