Synthetic resin laminate having photochromic properties and lens using same

The present invention makes it possible to provide a synthetic resin laminate which is provided with two transparent synthetic resin layers (A), two or more functional layers (B) having photochromic properties that are interposed between the two synthetic resin layers (A), and a transparent resin layer (C) that is interposed between the two or more functional layers (B). The functional layers (B) each include a photochromic dye and are a hardened layer obtained from a diisocyanate and a polyol.
