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.
