A laminated film is provided, in which a laminated layer including at least 50 percent by weight of composition (A) and cross-linking agent (B) is laminated on at least one surface of a thermoplastic resin film, wherein the composition (A) is a composition comprising a polythiophene and a polyanion or a composition comprising a polythiophene derivative and a polyanion, and the laminated layer has a sea-island structure in which the cross-linking agent (B) is present in the composition (A). Consequently, a laminated film exhibits an unprecedentedly high level of antistatic property unaffected by changes in humidity, and has excellent transparency, water resistance, and scratch resistance.

Layered film and process for producing layered film

Provided is a laminated polyester film, in which a laminated layer comprising two types of polyester resins having different glass transition points from each other is formed on at least one side of a base polyester film wherein the two types of polyester resins are composed of a polyester resin (A) having a glass transition point of from 60&deg; C. to 100&deg; C., and a polyester resin (B) having a glass transition point of from 0&deg; C. to 60&deg; C. and the polyester resin (B) contains a specified component, and a dicarboxylic acid component having a sulfonic acid metal base is set as a specified ratio of the entire dicarboxylic acid components in the polyester resins (A) and (B), satisfies adhesiveness to various types of coating materials which has conventionally been incompatible and, further, satisfies anti-blocking properties, transparency, scratch resistance and the other properties.

Laminated polyester film

A laminated film for thermosensitive image transfer material, comprises a biaxially oriented polyester film including at least one surface thereof a laminated layer containing 50% by weight or more of a wax-based compound, wherein the laminated layer has island-like protrusions, wherein the island-like protrusions have stripe-like protrusions on their surfaces, and wherein a density of the island-like protrusions is 2 to 100 protrusions/100 &mgr;m . Such laminated film for thermosensitive image transfer material has excellent hot sticking resistance even in a high energy-applied range, slidability, and printability that cannot be achieved conventionally.
