Abstract:
There is provided an anti-Newton ring sheet having an excellent anti-sparkle property, which can prevent the generation of sparkles when it is used in a touch panel using a high-definition color display, and a touch panel using this anti-Newton ring sheet.The anti-Newton ring sheet 1 of the present invention has an anti-Newton ring layer 3 comprising ionizing radiation curable organic-inorganic hybrid resin (binder component 32) and fine particles 31 on one surface of a transparent substrate 2, and preferably the mean diameter and the coefficient of variation of the diameter of the particle 31 is not less than 0.5 μm and not more than 3.0 μm and not less than 20% and not more than 80%, respectively, and the thickness of the anti-Newton ring layer 3 is preferably not less than 0.2 μm and not more than 3.5 μm.
