Abstract
A non-visible light reflective pattern-printed transparent sheet having a broad read angle is provided. The above transparent sheet is a pattern-printed transparent sheet in which a transparent substrate comprises a base material and a primer layer, and a non-visible light reflective transparent pattern is printed on the surface of the primer layer; an ink constituting the transparent pattern described above contains a material having a wavelength selective reflectivity to a wavelength in an infrared or ultraviolet region; the primer layer described above comprises a primer composition repelling the ink described above; when a cross section obtained by cutting the transparent pattern described above in a face orthogonal to the above transparent substrate is observed under a scanning electron microscope, the transparent pattern described above comprises a multilayer structure comprising a fixed repeating cycle and having a curved part and reflect selectively one of a left circularly polarized light component and a right circularly polarized light component in an incident light.
