PROBLEM TO BE SOLVED: To provide a temperature-dependent, color memorizing, and light transmitting resin laminated body having excellent transparency at the time of coloring and decoloring. SOLUTION: A laminated body 1 is formed by layering a reversible thermochromism layer 3 on a surface of a support body 2. The reversible thermochromism layer 3 consists of a composition formed of (a) an electron donating color organic compound, (b) a compound having phenol hydroxyl, and (c) a reversible thermochromism component consisting of a homogeneous compatible body which contains a compound selected from among alcoholic, ester, ketone, or carboxylic acid, which are fixed in a specified resin into a dispersed state or a solid solution state. The laminated body 1 satisfies an expression 0.50<=CT<=2.30, wherein 0.05<=C<=0.30, 1.0<=T<=40.0, C indicates a part by weight/[(c) component + matrix resin], and T indicates a film thickness (μm) of the reversible thermochromism layer. |
