Abstract
The present invention relates to a golf ball that provides improved playing characteristics by providing a cushioning interface between a center and subsequent layers. The ball can include a center, a soft intermediate layer, and a cover, although various constructions and modifications are possible. The intermediate layer can include an elastomeric latex or solution that will dry to form a soft film on the surface of the center. Such a soft rubber interlayer can serve as a cushioning interface to help improve durability and softness of the ball upon club impact. In another embodiment, the thin intermediate layer includes a responsive viscoelastic composition that exhibits an increase in viscosity under shear forces.
