Naphthalene dicarboxylic acid and ester substituted with aroyl group (NAPHTHALENE DICARBOXYLIC ACIDS AND ESTERS SUBSTITUTED WITH AROYL GROUPS)

摘要

The present invention relates to a naphthalene dicarboxylic acid or naphthalene dicarboxylic acid ester substituted with an aroyl group.;More specifically, the present invention relates to the following compounds: dialkyl 1-benzoyl-2,6-naphthalenedicarboxylate, 7-C_One-C₈-alkoxycarbonyl-1-C /RTI _One-C₈(1, 2-c.) Furan-3-one) and dialkyl 1-(2-naphthoyl)-2,6-naphthalenedicarboxylate The compound is useful in any polymer composition in which the dicarboxylic acid or dicarboxylic acid ester is used, especially in the poly (ethylene 2,6-naphthalenedicarboxylate) composition, and is preferred for reducing fluorescence.
