Disclosed are a liquid-crystalline resin laminated film comprising a liquid-crystalline resin layer and a non-liquid-crystalline thermoplastic resin layer laminated on at least one surface of the liquid-crystalline resin layer, and having an interlayer adhesiveness of at least 30 N/cm; and a liquid-crystalline resin laminated film comprising a liquid-crystalline resin layer and a non-liquid-crystalline thermoplastic resin layer laminated on at least one surface of the liquid-crystalline resin layer, and satisfying TN≧TL wherein TN and TL indicate the thermal deformation temperature of the non-liquid-crystalline thermoplastic resin layer and that of the liquid-crystalline resin layer, respectively, measured through thermal mechanical analysis (TMA). These are obtained by forming a non-liquid-crystalline thermoplastic resin layer on at least one surface of a liquid-crystalline resin layer through co-extrusion, followed by stretching the resulting laminated film.
A liquid-crystalline resin laminated film comprising a liquid-crystalline resin layer and a non-liquid-crystalline thermoplastic resin layer laminated on at least one surface of the liquid-crystalline resin layer, which is characterized in that its interlayer adhesiveness is at least 30 N/cm and which is further characterized in that it satisfies TN≧TL wherein TN and TL indicate the thermal deformation temperature of the non-liquid-crystalline thermoplastic resin layer and that of the liquid-crystalline resin layer, respectively, measured through thermal mechanical analysis (TMA).
A method for producing a liquid-crystalline resin laminated film, which comprises applying a non-liquid-crystalline thermoplastic resin layer on at least one surface of a liquid-crystalline resin layer by co-extrusion, followed by stretching to form a laminated film having an interlayer adhesion of at least 30 N/cm:
A method for producing a liquid-crystalline resin laminated film, which comprises applying a non-liquid-crystalline thermoplastic resin layer on at least one surface of a liquid-crystalline resin layer by co-extrusion, followed by stretching to form a laminated film having an interlayer adhesion of at least 30 N/cm, wherein the film is heated after co-extrusion and before stretching.
A method for producing a liquid-crystalline resin laminated film, which comprises applying a non-liquid-crystalline thermoplastic resin layer on at least one surface of a liquid-crystalline resin layer by co-extrusion, followed by stretching to form a laminated film having an interlayer adhesion of at least 30 N/cm, wherein the film is stretched at a temperature at which the liquid-crystalline resin layer melts and the non-liquid-crystalline thermoplastic resin layer softens but does not substantially melt.
