Claim Text:
1. An organic resin laminate having weather resistance and mar resistance, comprising an organic resin substrate and a multilayer coating system on a surface of the substrate, the multilayer coating system including an outermost layer (I) which is a hard film resulting from plasma polymerization of an organosilicon compound and an intermediate layer (II) which is a cured film formed from a composite coating composition (2), the intermediate layer (II) having one surface disposed contiguous to the outermost layer and another surface disposed contiguous to the organic resin substrate, wherein the composite coating composition (2) comprises wherein the outermost layer (I) includes an inner sub-layer and an outer sub-layer, wherein the inner sub-layer has a refractive index in the range of 1.449 to 1.463 and the outer sub-layer has a refractive index in the range of 1.430 to 1.434; wherein the inner sub-layer has a nano-indentation hardness in the range of 1.616 to 1.676 GPa and the outer sub-layer has a nano indentation hardness in the range of 2.265 to 2.667GPa; and wherein the inner sub-layer is contiguous with the intermediate layer (II).
