ABSTRACT:
The present invention provides an aromatic liquid crystalline polyester film excellent in the adhesion property to a substrate. Such film is obtained by an aromatic liquid crystalline polyester film obtained by casting an aromatic liquid crystalline polyester solution composition containing a solvent containing a halogen-substituted phenol defined by the following general formula (I):(wherein A is a halogen atom or a trihalomethyl group; i is an integer of 1 to 5; and in the case i is 2 or higher, the respective A may be the same or different), an aromatic liquid crystalline polyester, and a non-liquid crystalline resin at ratio of 1 to 200 parts by weight of the non-liquid crystalline resin to 100 parts by weight of the aromatic liquid crystalline polyester on a substrate; and removing the solvent.)
