Beschreibung
Zusammenfassung:	The invention relates to a solid plate consisting of a composition of a transparent polycarbonate with a molar mass of Mw of between 16,000 and 21,000 g/mol and an MFR of between 50 and 80 cm3/(10 min) (3000C; 1.2 kg), and transparent polymer particles having an optical density which is different from that of matrix materials. The invention also relates to the use of one such solid plate as a diffuser plate in flat-panel monitors. La presente invencion se refiere a una hoja solida que consiste de una composicion que comprende un policarbonato transparente que tiene una masa molar de Mw = 16,000 a 21,000 g/mol y un MFR = 50 A 80 cm3/(10 minuto) (300 degree C, 1.2 kg) y particulas polimericas transparentes; que tienen una densidad optica que difieren de aquella del material de matriz, y el uso de tal hoja solida como una hoja difusora en pantallas planas.
