LIGHT REFLECTING MATERIAL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a light reflecting material which is excellent in ultraviolet ray resistance and a light shielding property without spoiling characteristics of a polycarbonate resin, which has high light reflectivity and excellent durability and which is suitable for a light reflection plate of thin and large size and its peripheral parts and further to provide its manufacturing method.

SOLUTION: The light reflecting material has a weather resistant layer with a ultraviolet ray absorption function and ≥25μm thickness on one surface of a light reflecting layer consisting of a polycarbonate resin composition containing titanium oxide (b) of 5 to 50 parts weight toward 100 parts weight of an aromatic polycarbonate resin (a) and has a light shielding layer on another surface.
