ABSTRACT:
A golf ball comprising a core and at least one cover layer disposed about the core, the core comprising a geometric center and an outer surface, the core further comprising an untreated region extending radially from the geometric center a predetermined distance DUTrand a treated region disposed about the untreated region and extending inward from the outer surface a predetermined depth DTr. The treated region has been exposed to and comprises a fatty acid and/or fatty acid salt composition wherein the treated region comprises a first hardness and the untreated region comprises a second hardness different than the first hardness. Additionally, a golf ball comprising a core and a cover, the core comprising a geometric center and an outer surface, the outer surface comprising a fatty acid and/or fatty acid salt composition, the geometric center having a hardness (Hg) and the outer surface having an extrapolated hardness (HE) and an actual hardness (HOS) wherein HEis derived from a five point extrapolation within three quarters of an outer core diameter and HOSas measured on the curved surface of the core, and the cover has a hardness (HC), wherein HC>HE>Hg>HOS.
