Abstract
The pattern printed sheetof the present invention includes a substrateand a non-visible light-reflective transparent patternprinted on a surface of the substrate, wherein an ink for forming the transparent patterncontains a non-visible light-reflective material capable of selectively reflecting a light having a wavelength in a non-visible light range, and the transparent patternprinted on the surface of the substratehas a multilayer structure in section which is repeated at predetermined intervals as observed by a scanning electron microscope, and reflects only a circular polarization component in a predetermined rotation direction relative to an incident light applied thereto. The pattern printed sheet is usable as a coordinate detecting means which is applicable a data input system of a type capable of directly hand-writing input data on an image screen of a display device, and has a reduced weight and a low price, and is readily obtained in the form of a large area sheet and can be mass-produced.
