Title:
The golf ball incorporating a thin vapor barrier layer
Document Type and Number:
Japanese Patent JP6219421
Kind Code:
B2
Abstract:
Golf ball comprising a first layer having a first spherical outer surface; a thin moisture vapor barrier layer disposed concentrically about the first spherical outer surface and having a thickness of less than about 0.010 inches; and a second layer disposed concentrically about a second spherical outer surface of the thin moisture vapor barrier layer. The thin moisture vapor barrier layer is formed from an ionomer composition consisting of a 1-50 percent aqueous mono-valent high acid ionomer dispersion, with the ionomer: having an acid level greater than 18%; having more than 45% of acid groups that are neutralized with a monovalent cation; and being formed from an acid copolymer having a starting melt index of greater than 180 g/10 min.@190° C. with a 2160 g load. The moisture vapor barrier layer has a moisture vapor transmission rate that is lower than that of at least one of the first layer and/or the second layer.
