Abstract
An artificial marble includes unsaturated polyester resin (A), compound including silica (B), and luminescent pigment (C). An artificial marble according to a second embodiment includes about 70 to about 95% by weight of a non-luminescent base material (I) comprising unsaturated polyester resin (A), compound including silica (B), and organic/inorganic pigment (C) and about 5 to about 30% by weight of a luminescent amorphous pattern part (II) comprising unsaturated polyester resin (A), compound including silica (B), and luminescent pigment (D). An artificial marble according to a third embodiment includes unsaturated polyester resin (A), compound including silica (B), and amorphous luminescent chip (C).
