  • Patent number: 5880150
    Abstract: An antimicrobial agent comprising allyl isothiocyanate (AIT) packaged in a packaging material having a structure wherein part of the pores of a porous packaging substrate is filled with, or said pores are partially or entirely narrowed by a resin impervious to AIT vapor, and a method for controlling the AIT vapor release speed comprising enclosing AIT in the above-mentioned packaging material. According to the present invention, the AIT vapor release speed can be controlled, whereby enabling sustained release of AIT vapor and persistent effect of antimicrobial action. In addition, the antimicrobial agent of the present invention can be widely applied to food industries and various other fields where breeding and reproduction of deleterious microorganisms pose problems, since it is economical, compact and easy to use.

  • Patent number: 5554376
    Abstract: An self-adhesive article which is produced by forming an adhesive layer from an adhesive consisting essentially of a polymer of which is soluble in or swellable by an iso-thiocyanate, impregnating the adhesive layer with an iso-thiocyanate to provide a biocidal self-adhesive, and applying the biocidal self-adhesive to at least one surface of a base material. A high concentration of the iso-thiocyanate can be held in the adhesive layer, and the self-adhesive article is put to uses intended for the purpose of providing bactericidal, fungicidal and microbiocidal effects in building and food-related fields and the like.
