Abstract

Provided are a resin blend for forming a layer-separated structure, a pellet, a method of preparing a resin article using the same and a resin article. The resin blend may include a first resin, and a second resin that comprises an acrylic copolymer containing a silica particle and has a molecular weight distribution of 1 to 2.5. The resin blend can improve surface characteristics of a resin article. Also, the resin blend can realize excellent scratch resistance of a resin article. Further, since an additional coating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.
