Method for producing laminate

摘要

A laminate is produced from a film of a liquid crystal polymer forming an optically anisotropic molten phase and a metal foil by thermocompression bonding of a pile of the two between pressing rolls and the method comprises using a metal roll coated with a resin such as fluororubber and polyimide to a thickness of 0.02-5 mm as at least one of the pressing rolls or piling a heat-resistant film on the surface of a pile of polymer film and metal foil contacting a metal pressing roll and passing the resulting pile between metal pressing rolls. The method is capable of producing a laminate of good heat resistance from a liquid crystal polymer film and a metal foil with sufficient adhesion between the two at high productivity.
