Abstract
The present invention relates to a resin mixture for melt processing, comprising a first resin; and a second resin comprising an acrylate-based copolymer including silica particles and having a polydispersity index (PDI) of 1 to 2.5, a method for preparing a resin-molded article using the same, and a resin-molded article. Surface characteristics of the molded article can be improved and excellent scratch resistance can be obtained by using the resin composition. In addition, processing time can be reduced, productivity is increased, and manufacturing costs are lowered by omitting the additional surface coating step.
