Procedure
The polymer composition forming the supporting film of the present invention may be the polyester-a alone. This polyester-a is a copolyester containing ethylene terephthalate units as a main recurring unit and having a melting point of 210 to 250° C. The polyester-a is obtained from terephthalic acid as an acid component, ethylene glycol as a glycol component and further a copolymer component. The copolymer component may be either an acid component or a glycol component. Illustrative examples of the acid component include aromatic dibasic acids such as isophthalic acid, phthalic acid and naphthalenedicarboxylic acid; aliphatic dicarboxylic acids such as adipic acid, azelaic acid, sebacic acid and decanedicarboxylic acid; alicyclic dicarboxylic acids such as cyclohexanedicarboxylic acid; and the the like. Illustrative examples of the glycol component include aliphatic diols such as butane diol and hexane diol; alicyclic diols such as cyclohexane dimethanol; and the like. They may be used alone or in combination of two or more.
