Abstract:
The transparent resin substrate has a light-transmitting thermoplastic resin underlying sheet 1 and a hard coating formed on one surface of the underlying sheet, wherein the hard coating includes a resin component obtained by curing an urethane acrylate that contains a tri-functional or less functional urethane acrylate and a tetra-functional or more functional urethane acrylate; a silane coupling agent or a hydrolyzed product thereof, a silica sol having a grain size of 5 to 500 nm and a refractive index in a range of 1.44 to 1.5; and a metal chelate compound. A low refractive index layer is formed on the hard coating, the low refractive index layer includes a low refractive index hollow silica sol having a grain size of 10 to 150 nm and a refractive index of not more than 1.44, the silane coupling agent or the hydrolyzed product thereof, and a metal chelate compound.
