Abstract
In a golf ball comprising a core and a cover of plural layers, a cover inner layer is formed primarily of an ionomer resin in admixture with a compound containing at least two reactive functional groups and having a molecular weight of up to 20,000 and a cover outer layer is formed primarily of a non-ionomer resin. The ball is fully durable to repeated impact, and maintains good spin performance, rebound characteristics and feel even after repeated impact.
