Abstract
An antistatic adhesive article which comprises an adhesive layer and utilizes vanadium oxide to impart antistatic properties to the article. The article is preferably an adhesive tape or sheet. The adhesive may be pressure sensitive or non-pressure sensitive. The vanadium oxide may be incorporated into or onto the tape from an aqueous dispersion.
Claims31
An adhesive tape or sheet comprising (a) an exposed adhesive layer selected from the group consisting of pressure sensitive adhesives, and heat or radiation activated adhesives, and (b) a sufficient concentration of vanadium oxide so as to impart antistatic properties to the tape or sheet.
An adhesive tape or sheet comprising an adhesive layer coated on a first surface of a support layer, and a sufficient concentration of a vanadium oxide coated over said adhesive layer so as to impart antistatic properties to the tape or sheet.
A pressure sensitive adhesive tape or sheet comprising an exposed pressure sensitive adhesive layer and a sufficient concentration of vanadium oxide so as to impart antistatic properties to the tape or sheet.
A pressure sensitive adhesive tape or sheet comprising (a) a support layer, (b) an exposed pressure sensitive adhesive layer and (c) a dried product of an aqueous dispersion of vanadium oxide.
An adhesive tape or sheet comprising a support layer having first and second opposite parallel surfaces, a pressure sensitive adhesive layer on said first surface of said support, a dried aqueous dispersion of a vanadium oxide, and a layer of a low adhesion backsize on said second surface.
An adhesive tape or sheet comprising (a) an exposed adhesive layer capable of being adhered to a surface by the application of pressure, heat, and radiation, and (b) a sufficient amount of vanadium oxide anywhere in said tape or sheet so as to impart antistatic properties to said tape or sheet.
