Claim Text:
1. A resin article, comprising: a first resin layer including an acrylonitrile butadiene styrene (ABS) resin; a second resin layer including a (meth)acrylate-based resin having a molecular weight distribution of 1.9 to 2.2 and a weight average molecular weight of 30,000 to 200,000 formed on the first resin layer; and an interface layer including the ABS resin and the (meth)acrylate-based resin and formed between the first resin layer and the second resin layer, wherein the (meth)acrylate-based resin includes at least one selected from the group consisting of glycidyl methacrylate, perfluorohexylethyl methacrylate, tertiary butyl methacrylate and phenyl methacrylate in a polymerized form; wherein the resin article has a layer-separated structure formed during a melting process performed under a shear rate of 100 to 1000 s −1 using a twin-screw extruder or an injector, wherein the first resin layer and the second resin layer have a difference in melt viscosity of 0.1 to 3000 pa*s at a shear rate of 100 to 1000 s −1 and 210 to 240° C., and wherein the interface layer has a thickness of 0.01 to 95% based on the total thickness of the first resin layer and the second resin layer.
