ABSTRACT:
This invention relates to naphthalene dicarboxylic acids or naphthalene dicarboxylic esters substituted with aroyl groups. More particularly, this invention relates to the following compounds: dialkyl 1-benzoyl-2,6-naphthalene dicarboxylate, 7-C1-C.sub.8 -alkoxycarbonyl-1-C1-Cs-alkoxy-l-aryl(1,3-H.sub.2 naphtho {1,2-c} furan-3-ones), and dialkyl 1-(2-naphthoyl)-2,6-naphthalene dicarboxylate. The compounds are useful in any polymer composition where dicarboxylic acids or dicarboxylic esters are used especially in poly(ethylene 2,6-naphthalene dicarboxylate) compositions where reduced fluorescence is desired.
