Document Type and Number:
WIPO Patent Application WO/2020/022204
Kind Code:
A1
Abstract:
Provided is a laminated body that generates a structural color, wherein the laminated body can be subjected to a deep-drawing process without compromising the color-generation structure of the structural color. This laminated body has a polyamide layer (1) and a thermoplastic polyurethane layer (2) that comprises a color-generation structure of a structural color. A thermoplastic polyurethane layer that has a structure having recesses and protrusions on the surface opposite that in contact with the polyamide layer (1), or a layer obtained by laminating together two thermoplastic polyurethane layers for which the difference in refractive index is 0.03 or higher, is preferred as the thermoplastic polyurethane layer (2).
