LIGHT-SHIELDING HIGHLY REFLECTIVE POLYCARBONATE MULTILAYER SHEET, AND THERMOFORMED BODY AND CASE USING SAME

摘要

Disclosed is a light-shielding highly reflective multilayer sheet composed of at least two layers wherein the total light reflectance (Y value) of the front surface of the first layer is not less than 96%, the total light reflectance (Y value) of the opposite outermost surface of the first layer of the multilayer sheet is not more than 30%, and the total light transmittance of the multilayer sheet is not more than 0.3%. Such a light-shielding highly reflective multilayer sheet enables to prevent light leakage from a lamp holder portion when used for light reflection in a liquid crystal backlight unit or the like, and also enables to integrate a plurality of components of a backlight unit due to improvement in processability of the sheet. Also disclosed are a thermoformed body and a case composed of such a light-shielding highly reflective multilayer sheet.
