    摘要: A golf ball 2 includes a center 12, a mid layer 14, a reinforcing layer 6, a cover 8 and a paint layer 10. The golf ball 2 has a large number of dimples 16 on the surface thereof. The cover 8 is formed of a resin composition including thermoplastic polyurethane (A) and a polyisocyanate mixture (B). The polyisocyanate mixture (B) includes a urethane prepolymer (B1) having two or more isocyanate groups or an isocyanate compound (B2) having three or more isocyanate groups. The polyisocyanate composition (B) further includes a thermoplastic resin (B3) which substantially does not react with an isocyanate goup. The golf ball 2 is obtained by a mold having protrusions which projects from the equator of the mold. Each protrusion includes a part of a pimple.

    摘要: An object of the present invention is to provide a novel golf ball that controls the spin rate on the approach shots while suppressing the change in the spin rate on the driver shots and a method for producing the same. The present invention provides a golf ball having a cover containing a resin component and a filler, wherein the filler is oriented roughly parallel to a surface of the cover. The cover having anisotropy behaves like a hard material against the deformation in the compression direction on the driver shots and behaves like a soft material against the deformation in the shear direction on the approach shots. The present invention also provides a method for producing a golf ball, comprising compression molding a cover composition containing a resin component and a filler to mold a shell, and compression molding a core covered with a plurality of shells to mold a cover.
