  • OPTICALLY CLEAR AND ANTISTATIC PRESSURE SENSITIVE ADHESIVES
    Publication number: 20070141329
    Abstract: The present invention is directed to an antistatic pressure sensitive adhesive. The antistatic pressure sensitive adhesive comprises a pressure sensitive adhesive, and an antistatic agent comprising at least one organic salt. Certain embodiments of the antistatic pressure sensitive adhesive also have a luminous transmission of greater than about 89% according to ASTM D 1003-95. Additional embodiments of the antistatic pressure sensitive adhesive have a haze of less than about 5% according to ASTM D 1003-95, and in specific embodiments the haze is less than about 2% according to ASTM D 1003-95.
