PROBLEM TO BE SOLVED: To provide an aromatic liquid crystal polyester film double-sided with substrates having high adhesiveness between the aromatic liquid crystal polyester film and the substrates. SOLUTION: (1) The method for manufacturing the liquid crystal polyester film double-sided with the substrates comprises (i) a process for manufacturing a laminated body 1 by casting an aromatic liquid crystal polyester solution composition containing an aromatic liquid crystal polyester and a solvent on a first substrate, (ii) a process for manufacturing a laminated body 2 having the aromatic liquid crystal polyester film consisting of an aromatic liquid crystal polyester with a melting point of≥340°C or with substantially no melting point by heat-treatment of the laminated body 1 obtained by (i), and (iii) a process for heat-pressure bonding a second substrate on the face which is not brought into contact with the first substrate of the laminated body 2 obtained by (ii) at 300-360°C. (2) The liquid crystal polyester film double-sided with the substrates is obtained by this method for manufacturing. COPYRIGHT: (C)2008,JPO&INPIT |
