<p>The present invention relates to blends containing naphthalenedicarbonyl components displaying reduced fluorescense. Specifically the blends comprise: (a) a polyester/amide comprising: (1) a dicarboxylic acid component comprising at least 0.1 mol % of at least one naphthalenedicarboxylic acid, naphthalenedicarboxylate ester or mixture thereof; (2) a diol and/or diamine component; (3) 0.1 to 99.9 mol %, based on 100 mol % dicarboxylic acid and 100 mol % diol, of a copolymerizable fluorescence quenching compound; and (b) a second polymer selected from the group consisting of poly(alkylene terephthalate) homo and copolyesters, poly(alkylene naphthalate) homo and copolyesters, poly(cycloalkylene terephthalate) homo and copolyesters, poly(alkylene 1,4-cylcohexanedicarboxylate) homo and copolyesters, and polycarbonate homo and copolymers.</p> |
