A method of quenching fluorescence of a naphthalate polyester that is subjected to UV-radiation in an amount sufficient to cause the naphthalate polyester to reach an excited state and fluoresce, comprising adding to the naphthalate polyester a fluorescence quenching amount of a compound of formula (1): n n n n n n n n n n wherein R 1 is an alkoxy; R 2 is an organic linker; k is either zero or one; l is either zero or one, wherein the sum of k+l is one; and m is an integer in a range from zero to about twenty. |
