There are disclosed an artificial marble containing pellet-shaped
transparent chips, obtained by coating the outer surface of an internal
transparent resin layer with a resin layer containing a filler having a
high specific gravity using co-extrusion, and a process for preparing the
same. The artificial marble using the transparent chips as coloring
chips, thus not causing the occurrence of layer separation of the
transparent chips, which conventionally occurred in an artificial marble
using transparent chips made of a single component, being distinguished
from a conventional artificial marble made of combination of the
single-colored chips, and expressing a pattern similar to a natural
granite.
