  A method for preventing the emission of fluorescence from polyalkylenenaphthalene-2,6-dicarboxylate, comprising mixing polyalkylenenaphthalene-2,6-dicarboxylate and at least one compound selected from cyclic imino esters and quinoxalines. The above cyclic imino esters and quinoxalines have an absorption intensity E, defined by the following expression:E 1cm1%= A/c.d    wherein A is an absorbance measured in 1,1,2,2-tetrachloroethane at a concentration c (g/100 ml) and an optical path d (cm), of more than 200 at an ultraviolet wavelength range of 340 to 400 nm. And when a coating layer containing at least one ultraviolet absorber is formed on the surface of a molded article made of the above fluorescence-emission preventive mixture, a synergistic suppression of the emission of fluorescence can be obtained.
