Abstract
Abstract A coating layer of a polymer capable of forming an optically anisotropic melt phase is formed by heat-pressing to a base material a film made of the polymer and having a segment orientation ratio of not greater than 1.3 and then separating the film into two halves so as to leave one of the halves on the base material, thereby obtaining a coated material made of the base material and the thin coating layer. <IMAGE>

A coating method which comprises the steps of: applying to a base material a polymer film prepared from a polymer
capable of forming an optically anisotropic melt phase and having a segment
orientation ratio of not greater than 1.3; heat-bonding the polymer film to the base material to provide a laminate;
and peeling the film so as to leave a thin layer of the film on the base material.
