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 m2/g or less.

A composition for artificial marble, comprising:
- a binder resin;
- inorganic fillers excluding zinc oxide;
- and
- zinc oxide;
- wherein the zinc oxide has a peak intensity ratio (B/A) of about 0.01 to about 1, where A indicates a peak in the wavelength range of 370 nm to 390 nm and B indicates a peak in the wavelength range of 450 nm to 600 nm in photoluminescence measurement, a BET surface area of about 10 m2/g or less, as measured using a BET analyzer, a peak position degree (2θ) in the range of about 35° to about 37°, and a crystallite size of about 1,000 Å to about 2,000 Å in X-ray diffraction (XRD) analysis, as calculated according to Equation 1:
