Wrapped body

Abstract

The objective of this invention is to provide a wound body of an optically laminated body capable of suppressing adhesion of the optically laminated body to the end of a winding shaft. The winding system of this invention is a wound body formed by winding an optically laminated body. The optically laminated body has a substrate layer, a hardened layer of a curable composition formed on the substrate layer, and a light-absorbing anisotropic layer formed on the side of the substrate layer opposite to the hardened layer side. The light-absorbing anisotropic layer contains a polymer of a polymeric liquid crystal compound and a dichroic pigment, and has a light absorption axis in a direction perpendicular to the plane of the light-absorbing anisotropic layer. In a cross-section orthogonal to the winding direction of the optically laminated body, when the width of the substrate layer is set to A, the width of the hardened layer to B, and the width of the light-absorbing anisotropic layer to C, the following relationships (1) to (3) are satisfied. 0.90≤B / C≤1.10 (1) 0.90≤B / A<1.00 (2) 0.88≤C / A<1.00 (3)
