REFLECTION SHEET USING METHACRYLIC RESIN COMPOSITION AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reflection sheet in which yellow discoloration and deterioration of reflectance are suppressed over time and which has no unevenness of reflectance.SOLUTION: A reflection sheet is formed using a methacrylic resin composition containing methacrylic resin (A) which contains 80-98.5 wt.% methacrylic ester monomer units and 1.5-20 wt.% other vinyl monomer units copolymerizable with at least one kind of the methacrylic ester monomer and has a molecular weight distribution (Mw/Mn) of 2.20 or more and 6.00 or less in measurement by a gel permeation chromatography (GPC).
