    摘要： An embodiment according to one aspect of the present invention provides a marbled molded product obtained by injection-molding, in a mold cavity, a mixture comprising: a thermoplastic resin comprising one selected from the group selected from polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof; and fine pigment particles, wherein a pattern forming a texture is formed on the surface of the injection-molded product.
    An embodiment according to another aspect of the present invention provides a system for evaluating a marble color effect of a marbled molded product which is an injection-molded product of a mixture comprising: a thermoplastic resin comprising one selected from the group selected from polycarbonate, acrylonitrile-butadiene-styrene, polybutylene terephthalate, polypropylene, and combinations thereof; and fine pigment particles, the system comprising: a light source unit configured to emit light onto the surface of the molded product while forming an angle with the surface of the molded product; an image-capturing unit configured to capture an image of light scattered from the surface of the molded product; an image processing unit configured to process the image captured by the image-capturing unit in order to determine the boundaries of regions in which the marble color effect is created on the surface of the molded product; and an evaluation factor determination unit configured to determine a marble color effect evaluation factor from the image processed by the image processing unit.
