Claim Text:
1. A golf ball comprising: a first molded non-dissolvable layer having a first spherical outer surface; a dissolvable tie layer disposed concentrically about the first spherical outer surface by at least one of dipping, soaking, rolling, wiping, spraying, and brushing and being bonded with the first layer at an interface there between; a second molded non-dissolvable layer disposed concentrically about a second spherical outer surface of the dissolvable tie layer and being bonded with the dissolvable tie layer at an interface there between; wherein the dissolvable tie layer has a thickness of up to about 0.005 inches, and is formed from a tie layer composition consisting of a 1-50 percent aqueous mono-valent high acid ionomer dispersion; wherein the ionomer of the tie layer composition: (i) has an acid level greater than 18%; (ii) has more than 45% of acid groups that are neutralized with a monovalent cation; and (iii) is formed from an acid copolymer having a starting melt index of greater than 180 g/10 min.@190° C. with a 2160 g load; wherein the dissolvable tie layer is dispersible in water heated to a heating temperature of about 80° C.-90° C. or greater; and wherein the first molded non-dissolvable layer and the second molded non-dissolvable layer are not dispersible in water at the heating temperature.
