A dissipative waterborne laminating adhesive composition containing no conductive filler and comprising 90 to 99.5% by weight of an adhesive polymer prepared from vinyl or acrylic esters, blends thereof or blends thereof copolymerized with up to 30% ethylene and 0.5 to 10% by weight of a quaternary ammonium salts containing 1 to 7 carbon atoms.

Dissipative laminating adhesive

This invention presents a series of synthetic based cold seal adhesives which are capable of forming a strong bond at room temperature, yet which may be reeled up without blocking and stored for extended periods of time. Such adhesives can be used in place of the natural rubber based cold seal adhesives currently used, and thus, can be employed in any packaging application where cold seal properties are desirable.
