<p><P>PROBLEM TO BE SOLVED: To provide a light-transmitting hard coat film for a touch panel having high total light transmittance, and capable of generating a blue transmission color. <P>SOLUTION: On one surface of a light-transmitting base material film, (A) a light-transmitting hard coat layer formed of a hardened material of an ionizing radiation curing type compound, (B) a high-refraction-index layer formed of a hardened material of an ionizing radiation curing type compound containing a metal oxide of antimony-doped tin oxide and zirconium oxide and/or titanium oxide, and having a refraction index of 1.65-1.90 and a thickness of 30-160 nm, and (C) a low-refraction-index layer formed of a hardened material of a siloxane-based hardened compound, and having a refraction index of 1.40-1.55 and a thickness of 10-50 nm are sequentially stacked. <P>COPYRIGHT: (C)2004,JPO</p> |
