Abstract

A golf having hydrophilic and hydrophobic portions is disclosed. In wet playing conditions, moisture may be repelled by the hydrophobic portions and attracted to the hydrophilic portions. Thus, the surface of the hydrophobic portions may remain dry such that the friction between a golf club head and the golf ball surface is not reduced. As a result, the golf ball may not be adversely affected by wet playing conditions.

First claim

What is claimed is:

1. A golf ball comprising:
a core;
a cover layer surrounding the core, and having a surface including a plurality of dimple area surfaces and a plurality of land area surfaces between the plurality of dimple area surfaces, wherein at least a portion of the dimple area surfaces are more hydrophilic than the land area surfaces as determined by comparing the contact angles between the surfaces and a water droplet.

2. A golf ball comprising:…
