Abstract

Disclosed herein is a golf ball having a cover composed of a transparent reaction injection molded polyurethane material. The cover is transparent to visible light and allows for viewing of a core or boundary layer. The core or boundary layer may have a visually appealing color. Further, an indicia may be printed on a surface of the core or boundary layer, and the indicia is visible through the cover material.

Claims

1. A golf ball comprising:

a core comprising a polybutadiene mixture;

a boundary layer formed over the core, the boundary layer having a color selected from the group consisting of blue, red, white, green, yellow, orange, black, brown, pink, grey and purple;

an indicia printed on a surface of the boundary layer; and

a cover formed over the core, the cover composed of a fast chemical reaction aliphatic polyurethane material formed from reactants comprising 1,6, hexatmethylene-diisocyanate and a polytetramethylene ether glycol;

wherein the cover material is transparent to visible light and the boundary layer and indicia printed on the surface of the boundary layer are both visible through the cover material.
