Abstract
The present invention is directed towards a golf ball which comprises a core; at least one cover layer; at least one mantle layer disposed between the core and the cover; and at least one transition layer disposed between two of the other layers of the golf ball comprised of discrete portions of at least one of the adjacent layers. The transition layer may be formed by projections extending from one layer and cavities on the opposing layer for interlocking with the projections. The thickness of a first layer is X and the thickness of a second layer is Y and the thickness of the transition layer is Z. The Flexural Modulus of the first layer is E.sub.x and the second layer is E.sub.y. In the golf ball according to the present invention, Z is determined by the following formula: ##EQU1##
