Abstract
A coating composition for game balls, such as baseballs and softballs, is provided. The coating composition is comprised of a specific film-forming binder system, a fluorescent pigment, at least one compatible solvent and additional components including texturizing and leveling agents. The various constituents of the coating composition are combined together in predetermined, relative proportions to produce a composition which, when applied to a game ball such as a softball, provides a coating having qualities including a bright fluorescent color, excellent durability and weather resistance, as well as a soft leathery texture.
