Abstract:
1. A golf ball comprising: a core; a cover layer substantially surrounding the core, the cover layer including at least one dimple, and at least one land area adjacent to the dimple; and a coating layer overlapping at least a portion of the cover layer; the coating layer overlaps at least one dimple portion of the cover layer, and the coating layer overlaps at least one land area portion of the cover layer; the coating layer has a first thickness in locations where the coating layer overlaps the at least one land area portion; the coating layer has a second thickness in locations where the coating layer overlaps the at least one dimple portion; the second thickness is greater than the first thickness; and wherein the coating layer is a continuous material comprised of a hydrophilic water-swellable material with a constant swelling ratio, such that the coating layer is configured to undergo a uniform physical change from a dry state to a wet state upon exposure to water; wherein the dry state is associated with a first dimple depth, the wet state is associated with a second dimple depth, and the second dimple depth is less than about 75% of the first dimple depth.
