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 including a resin to which a fluorine or fluorine-substituted organic functional group is introduced and having a difference in surface energy from the first resin at 25° C. of 0.1 to 35 mN/m. The resin blend can improve mechanical and surface characteristics of a resin article. Also, the resin blend can realize excellent contamination resistance of a resin article. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.
