Abstract
The present invention is directed to golf balls comprising a cover and a core, wherein the cover is formed from a blend which comprises a base ionomer resin and a color concentrate comprising a coloring agent and a carrier ionomer resin. The relationship between the acid content of the base ionomer resin (X), wherein (X) is at least about 15% by weight and the acid content of the carrier ionomer resin (Y) is X-Y.ltoreq.4. Golf balls made with covers having base ionomer resins and carrier ionomer resins meeting the above relationship exhibit superior durability characteristics, including a significant reduction flow front failures and delamination as compared to golf ball covers which do not meet the above relationship.
