Patent ID: 8523237

Claim:
A reflected pattern-printed transparent sheet in which non-visible light reflective dot shaped transparent patterns are printed on a surface of a transparent substrate and which is mounted oppositely to a front face of a medium capable of displaying images, wherein an ink forming the dot shaped transparent patterns described above contains a non-visible light reflection material; the non-visible light reflection material is a material having a wavelength selection reflectivity to a wavelength in a non-visible light region; and a thickness of the above dot shaped transparent patterns is 6 to 20 μm; wherein the transparent substrate comprises a base material and a primer layer containing a liquid repellent leveling agent, and the dot shaped transparent patterns are printed on the surface of the primer layer; wherein the liquid repellent leveling agent is an acrylic acid copolymer base, wherein when a cross section obtained by cutting the dot shaped transparent patterns in a face orthogonal to the transparent substrate is observed under a scanning electron microscope, the dot shaped transparent patterns are formed so that they comprise a multilayer structure comprising a fixed repeating cycle; and wherein the multilayer structure is formed from a liquid crystal material having a fixed cholesteric structure.
