Abstract

This invention provides a laminate comprising a white protective layer. Even with repeated heating and cooling, the color of the laminate as viewed from the white protective layer side does not easily change. The laminate of this invention is characterized by the sequential deposition of a white protective layer and an adhesive layer, wherein the adhesive layer is a black adhesive layer. When the laminate is disposed on a black substrate such that the adhesive layer is in contact with the black substrate having an L* value of 34.25, an a* value of -0.15, and a b* value of -1.47, the L* value (B1-L) of the laminate as viewed from the white protective layer side is 84.00 to 88.00, and the a* value (B1-a) is -2.50 to 1.50. The b* value (B1-b) is -4.50 to 4.50. When the above-mentioned laminate is disposed on the yellow substrate in such a way that the adhesive layer is in contact with the yellow substrate with an L* value of 70.58, an a* value of 20.80, and a b* value of 57.34, the L* value (Y1-L) of the above-mentioned laminate viewed from the white protective layer side is 84.40 to 88.10, the a* value (Y1-a) is -2.60 to 1.50, and the b* value (Y1-b) is -4.00 to 4.50.
