摘要： The present invention comprises esters selected from the group consisting of esters of 1,6-naphthalene dicarboxylic acid and an aliphatic hydrocarbon alcohol having four to eight carbon atoms; esters of 2,3-naphthalene dicarboxylic acid and an aliphatic hydrocarbon alcohol containing five to eight carbon atoms; and esters of a naphthalene dicarboxylic acid and a branch chain alkane alcohol having at least two carbon atoms in the branch when the branch is closer to the hydroxyl-substituted carbon atom than the gamma position.
