摘要： The invention provides a golf ball having a solid core, a cover of at least one layer, and a plurality of dimples on a surface of an outermost layer of the cover. The dimples number at least 250 but not more than 500, and have a volume ratio (VR) of from 1.20 to 1.50%. The ball has a deflection, when compressed under a final load of 1,275 N (130 kgf) from an initial load state of 98 N (10 kgf), of from 4.0 to 6.0 mm. This golf ball is able to substantially reduce the distance traveled by the ball when struck at a high head speed, while at the same time holding down the decrease in distance when struck at a low head speed.

摘要： The invention provides a multi-piece solid golf ball having a solid core, an inner cover layer and an outer cover layer, which outer cover layer has a plurality of dimples on a surface thereof. The value obtained by subtracting a material hardness (Shore D) of the outer cover layer from a material hardness (Shore D) of the inner cover layer is greater than −5 and less than +5. The dimples number at least 250 and not more than 500, have a surface coverage (SR) of at least 70% and a volume ratio (VR) of at least 1.0%, are of at least three types of mutually differing dimple diameter (DM) and/or dimple depth (DP), and have an average depth of at least about 0.18 mm and a diameter-to-depth ratio (DM/DP) of not more than about 23. The ball has a coefficient of lift CL at a Reynolds number of 70,000 and a spin rate of 2,000 rpm which is maintained at 60% or more of the coefficient of lift CL at a Reynolds number of 80,000 and a spin rate of 2,000. This multi-piece solid golf ball is able to substantially reduce the distance traveled by the ball when struck at a high HS, while at the same time holding down the reduction in distance when struck at a low HS.

摘要： The invention provides a multi-piece solid golf ball composed of a solid core encased by a cover of one or more layer, which solid core has an inner core layer and an outer core layer. The inner core layer is formed primarily of a thermoplastic resin, has a diameter of from 21 to 38 mm, has a JIS-C cross-sectional hardness of from 60 to 83 at any single point on a cross-section obtained by cutting the inner core layer in half, and has a cross-sectional hardness difference between any two points on the cross-section of within ±5. The outer core layer is formed of a rubber composition made primarily of polybutadiene rubber. The solid core has a diameter of from 35 to 42 mm. The ball has specific relationships between the hardness of the inner core layer 1 mm inside a boundary between the inner core layer and the outer core layer, the hardness of the outer core layer 1 mm outside the boundary, and the surface hardness of the outer core layer. Such a golf ball is able to achieve an increased distance.

摘要： The invention provides a multi-piece solid golf ball having a solid core encased by a cover of one, two or more layers, the solid core including a spherical first layer, a second layer encasing the first layer and a third layer encasing the second layer. The first layer has a diameter of from 3 to 24 mm, and the third layer is formed of a rubber composition composed primarily of polybutadiene rubber. The ball has specific relationships between the cross-sectional hardness at the core center on a cut face when the solid core has been cut in half and the respective hardnesses of the first layer 1 mm inside an interface between the first layer and the second layer, the second layer 1 mm outside the interface between the first layer and the second layer, the second layer 1 mm inside an interface between the second layer and the third layer, the third layer 1 mm outside the interface between the second layer and the third layer, and the surface of the third layer. Such a golf ball has a high initial velocity when hit with a driver (W#1), and excessive spin receptivity on shots with a short iron is suppressed. As a result, an excellent flight performance is achieved, both on shots with a driver and on shots with a short iron. In addition, a good feel on impact can also be obtained.
