| 101 | Two-piece solid golf ball | US12470242 | 2009-05-21 | US08021249B2 | 2011-09-20 | Hiroshi Higuchi; Junji Umezawa; Katsunori Sato; Takuma Nakagawa |
| The invention provides a two-piece solid golf ball having a core and a cover, which ball has a plurality of dimples formed on the surface. The number of dimples is from 250 to 500, the dimples have a surface coverage (SR) of at least 70% and a volume ratio (VR) of at least 1.0%, and dimples of at least three types are used. In addition, the dimples 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 ratio 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 two-piece solid golf ball lowers fluctuations in lift and drag at high and low spin rates, enabling a stable trajectory to be achieved. | ||||||

| The invention provides a golf ball having a core, at least one intermediate layer encasing the core, and a cover. The intermediate layer is formed primarily of a specific ionomer resin composition that is highly neutralized. The cover is formed by injection molding a single resin blend composed primarily of a thermoplastic polyurethane and (g) a polyisocyanate compound in at least some portion of which all the isocyanate groups on the molecule are present in an unreacted state. The golf ball of the invention has a low spin rate on shots with a driver, enabling it to travel a good distance, and achieves a sufficient spin rate on shots with a short iron such as a wedge. The ball also has an excellent scuff resistance. | ||||||
