The present invention relates to a coating composition for covering golf balls. More particularly, the present invention relates to a matte coating composition mixed with a synthetic fatty acid resin derived from dehydrated castor oil. According to the present invention, a golf ball having a matte surface can realize a uniform and fine matte appearance and ensure a field of vision to enable high-precision hitting, faithfully express desired marks of various colors, characters and patterns applied thereto, and prevent surface yellowing caused by exposure to ultraviolet rays over a long period of time.
