SYNTHETIC RESIN LAMINATED BODY HAVING BOTH OF POLARIZING PROPERTY AND PHOTOCHROMIC PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a transparent synthetic resin laminated body having both of polarizing property and photochromic property. SOLUTION: The synthetic resin laminated body has two transparent synthetic resin layers, a resin layer having photochromic characteristics and a resin layer having polarizing characteristics held between the two transparent synthetic resin layers, and an adhesive layer which adheres the resin layer having the polarizing characteristics to the transparent synthetic resin layer, and the laminated body has both of polarizing characteristics and photochromic characteristics. The transparent synthetic resin layer of the two transparent synthetic resin layers which is in contact with the resin layer having photochromic characteristics has >=50μm thickness and the retardation of <=150 nm or >=3000 nm.
