Disclosed is an amorphous copolyester polymerized of a diacid and diols. The diacid is selected from a group consisting of terephthalic acid, 5-tert-butylisophthalic acid, and dimethyl 2,6-naphthalenedicarboxylate. The diols are selected at least two from a group consisting of ethylene glycol, 2,2-dimethyl-1,3-propanediol, and tricyclodecanedimethanol. The molar ratio of the tricyclodecanedimethanol is 30% to 95% of the diols.
