The present invention relates to an artificial pigment and a method of preparing the same, specifically to an artificial pigment with excellent dry pick resistance and a method of preparing the same. In order to accomplish the object, the present invention provides an artificial pigment of core-shell structure comprising; a) shell of butadiene polymer including. i) seed of butadiene polymer having glass transition temperature of -10 to 50° C., and ii) seed covering of butadiene polymer having glass transition temperature of -10 to 20° C., and b) core of styrene polymer having glass transition temperature of 40 to 120° C., and a method of preparing artificial pigment comprising a) preparing shell of butadiene polymer, and b) preparing core of styrene polymer inner side of said shell of a) step. The coating color comprising the artificial pigment of the present invention can make coated paper having excellent dry pick resistance and high paper gloss and printing gloss as well as stiffness.
