A laminate which has a high light reflectance and a whitish color, less deforms thermally, and has excellent heat resistance. The laminate has excellent weatherability and is less apt to undergo hydrolysis even when used outdoors for long. The laminate has excellent flexibility and is less apt to break even when in a film form. The laminate is satisfactory in processability, productivity, and handleability and is inhibited from curling. The laminate comprises a resin layer (B) as a base layer, a resin layer (A) superposed on one side thereof, and a resin layer (C) superposed on the other side thereof, the thickness (HA) of the resin layer (A), the thickness (HB) of the resin layer (B), and the thickness (HC) of the resin layer (C) satisfying the following relationships (1) and (2). The laminate has a dimensional change within ±1% through 30-minute standing at 150 °C and has a reflectance of 50% or higher as measured with light having wavelengths of 400-1,400 nm. 0.5=HA/HC=1.3 (1) 0.4=(HA+HC)/HB=2.4 (2) |
