Patent ID: 7820265

Claim:
A film of electrically heatable pressure-sensitive adhesive comprising (a) at least one adhesive component comprising a polymer of at least one acrylic monomer of the formula (1) where R 1 is H or a CH 3 radical and R 2 is H or is selected from the group consisting of saturated, unbranched or branched, substituted or unsubstituted C 1 to C 30 alkyl radicals, or a copolymer of said at least one acrylic monomer and a comonomer which is polymerizable with said at least one acrylic monomer, said at least one acrylic monomer forming at least 50% by weight of said polymer or copolymer, blended with (b) at least one electrically conductive filler material which develops heat when acted on by an electric current, and crosslinked, (c) at least one electrode attached to at least one side of said film, and (d) a source of electricity connected to said electrode.
