Abstract (en)
[origin: WO9834981A1] The present invention relates to an article formed from a polyester derived from an acid component comprising 2,6-napththalene dicarboxylate and attached to at least one surface of said article a coating layer having a cutoff wavelength between about 380 nm and about 410 nm and an absorbance of greater than about 2 at all wavelengths between 300 nm and 365 nm. The coating layers comprise at least one absorbing compound selected from benzylidene compounds, benzoxazinone compounds, triazine compounds, benzophenone compounds and benzotriazole compounds.
