Abstract

PURPOSE: To provide the titled structure which is suitable for use in solar battery, etc., absorbs light energy over a wide range and can convert light into one having a longer wavelength, by dissolving an anthraquinone fluorescent pigment in a polyalkylene terephthalate, and molding the resulting compsn.
CONSTITUTION: 0.001W1wt% at least one anthraquinone fluorescent pigment selected from pyranthrone, (iso)benzanthrone and dibenzopyrenequinone, is dissolved in a polyalkylene terephthalate such as polyethylene terephthalate. The resulting compsn. is molded into sheet, rod, pipe, fiber, etc. by a calendering molding method, a melt extrusion method, etc. Pref the compsn. is molded so as to give a ratio of absorbance area to emission area within the range of 10:1W105:1, to produce the desirved molded structure which can convert light in short wavelength zone into light having a longer wavelength with good weather resistance.
