    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 mixture (B) further includes a thermoplastic resin (B3) which substantially does not react with an isocyanate group. The golf ball 2 is obtained by a mold having protrusions which project from the equator of the mold. Each protrusion includes a part of a pimple.

    摘要: A golf ball 2 has a core, a mid layer and a cover. This mid layer comprises 10 parts by weight or greater and 70 parts by weight or less of a thermoplastic elastomer containing a styrene block having a material hardness of less than 10, and 30 parts by weight or greater and 90 parts by weight or less of an ethylene-(meth)acrylic acid copolymer based ionomer resin having a material hardness of 50 or greater and 70 or less. Hardness of this mid layer is less than 40, and the thickness is equal to or less than 1.2 mm. This golf ball 2 has seven kinds of dimples (A to G), each having a different diameter. When all the dimples are arranged in decreasing order of the diameter Di, ratio (Dx/Dn) of the mean diameter Dx of the dimples ranking in the top 10% to the mean diameter Dn of the dimples ranking in the bottom 10% is equal to or greater than 1.30. Standard deviation η of diameters of all the dimples is equal to or less than 0.52.

    摘要: Golf ball 1 has numerous dimples 4 on its surface. The dimple 4 comprises an inclined face 6, a circular flat face 7, an annular groove 8 and a round flat face 9. Surface area s1 is calculated by summing up the surface area of the inclined face 6, the surface area of the circular flat face 7, the surface area of the annular groove 8 and the surface area of the round flat face 9. The ratio (S1/S2) between a summation S1 of surface areas s1 of all the dimples, and a summation S2 of the areas s2 of the regions cut away by the dimples on the phantom spherical face is equal to or greater than 1.02. Total value (Cb+Cc) of the amount of compressive deformation Cb of the golf ball 1 and the amount of compressive deformation Cc of the core is equal to or greater than 7.0 mm.
