Abstract
A composition for artificial marble, of the present invention comprises: a binder resin; an inorganic filler excluding zinc oxide; and zinc oxide, wherein the zinc oxide has a size ratio (B/A), in which peak A is a 370 nm to 390 nm region and peak B is a 450 nm to 600 nm region, of approximately 0.01 to 1 during photoluminescence measurement, and has a BET surface area of approximately 10 m/g or less.
