Patent ID: 7678455

Claim:
A laminated film in which a laminated layer comprising composition (A) and epoxy-based cross-linking agent (B) is laminated on at least one surface of a thermoplastic resin film, wherein the 1) laminated layer comprises at least 70 percent by weight of both composition (A) and epoxy-based cross-linking agent (B) based on the total weight of the laminated layer, 2) epoxy-based cross-linking agent (B) is 40 to 85 percent based on the total weight of the laminated layer and provides a haze value of 1.8% or less, 3) composition (A) is a composition comprising a polythiophene and a polyanion or a composition comprising a polythiophene derivative and a polyanion, 4) epoxy-based cross-linking agent (B) has a molecular weight of 800 or less, 5) laminated layer has a sea-island structure in which the epoxy-based cross-linking agent (B) is present in the composition (A), 6) epoxy-based cross-linking agent (B) is a water-soluble cross-linking agent and 7) laminated layer has a surface resistivity (23° C. relative humidity 65 percent) of 3×10 8 Ω/□ or less.
