ABSTRACT:
Disclosed is a novel antistatic pressure-sensitive adhesive composition essentially comprising an aqueous latex copolymer of a vinyl ester and an alkyl acrylate to which an adhesive-compatible ammonium salt has been added. An antistatic pressure-sensitive adhesive is prepared by dispersing, as an antistatic promoter, a compatible ammonium salt, such as a quaternary ammonium salt, directly with the latex copolymer. By coating one side of a suitable release paper with the antistatic pressure-sensitive adhesive thus prepared and thereafter laminating the adhesive side of the coated release paper to a film material, the tendency for such materials to accumulate electrostatic charges upon the removal of the release paper is greatly reduced.
