Synthetic resin laminate having both polariztion characteristic and photochromism characteristic

摘要

A synthetic resin laminate having both phtochromism characteristic and polarization characteristic consisting essentially of two transparent synthetic resin layers, a resin layer having phtochromism characteristic and a resin layer having polarization characteristic interposed between said two transparent synthetic resin layers and an adhesive layer to adhere said resin layer having polarization characteristic to said one transparent synthetic resin layer, wherein said one transparent synthetic resin layer to contact said resin layer having phtochromism characteristic has a thickness of 50 mum or above and a retardation value of 150 nm or below, or 3000 nm or above.
