Abstract

PURPOSE: To prepare the titled article having the form of sheet, rod, etc., capable of converting the light having short wavelength to the one having longer wave length, and having high lihgt resistance, by dissolving a thioindigo-type or perinone-type fluorescent pigment in polyalkylene terephthalate.
CONSTITUTION: A thioindigo pigment such as methyl- or halogen-substituted thioindigo derivative, 6,6'-diethoxythioindigo, etc. or a perinone pigment such as 12H- phthaloperi-12-one or its derivative, is dissolved in a polyalkylene terephthalate, pref. polyethylene terephthalate at a concentration of 0.001W0.4wt%, pref. 0.005W 0.3wt%. The composition is formed to a sheet, film, pipe, etc. pref. having the transparent index of ≤10. When the ratio of absorbing area to the light-emitting area is between 10:1 and 105:1, pref. between 50:1 and 104:1, high intensity light can be collected to the radiation surface.
