Application 10/167,744
a harder, stiffer, more resilient ball with a softer, more responsive ball.
More particularly, the invention relates to a golf ball with at least two
covers, e.g., an inner cover and an outer cover, wherein the layers have the
same Shore hardness, at least one cover layer is formed of a polymer blend
including a polyurethane composition, and at least one cover layer is formed
of a different polymer blend. The invention further relates to a golf ball
having a core and two or more cover layers, wherein the multiple cover
layers are formed from materials that are substantially the same composition
with the same Shore hardness, but are modified in some way to alter the
processing or performance characteristics of the golf ball (Specification
[0001]). Independent Claims 1 and 19 are reproduced below:
1. A golf ball comprising:
a core;
a cover disposed about the core, comprising:
an inner cover layer formed from a first composition having a
first hardness and a first coefficient of friction; and
an outer cover layer formed from a second composition
having a second hardness and a second coefficient of
fiction, wherein the second hardness differs from the first
hardness by about 5 points or less, and wherein the
second coefficient of friction is greater than the first
coefficient of friction.
19. A golf ball comprising:
a core;
a cover disposed about the core, comprising:
