摘要： An engineered stone includes a light transmitting mother material (I) and a phosphorescent chip (II). The light transmitting mother material (I) includes about 7 wt % to about 12 wt % of an unsaturated polyester resin (A) and about 88 wt % to about 93 wt % of a silica-containing compound (B) based on a total amount of the unsaturated polyester resin (A) and the silica-containing compound (B) of the light transmitting mother material (I), and further includes about 0.01 part by weight to about 1 part by weight of an organic/inorganic pigment (C) based on about 100 parts by weight of the unsaturated polyester resin (A). The phosphorescent chip (II) includes about 8 wt % to about 15 wt % of an unsaturated polyester resin (A′), about 85 wt % to about 92 wt % of a silica-containing compound (B′) based on a total amount of the unsaturated polyester resin (A′) and the silica-containing compound (B′) of the phosphorescent chip (II), and further includes about 2 parts by weight to about 10 parts by weight of a phosphorescent pigment (D) based on about 100 parts by weight of the unsaturated polyester resin (A′). The silica-containing compound (B′) includes about 20 wt % to about 30 wt % of a silica powder (b1′) based on a total amount of the phosphorescent chip (II).
