Provided is a photochromic coating composition that includes: a polyrotaxane (A) having a complex molecular structure comprising an axle molecule and a plurality of cyclic molecules enclosing the axle molecule; a photochromic compound (B); and a polyurethane resin and/or a precursor thereof (C). This composition provides a laminate that exhibits excellent photochromic properties (optical density and fading speed), formability, and surface hardness. |
