Abstract:
In a multi-piece solid golf ball having a rubber two-layer core consisting of an inner layer and an outer layer, a cover, and at least one intermediate layer therebetween, the inner core layer has a diameter of at least 22 mm, the difference in JIS-C hardness between the center of the inner core layer and the surface of the outer core layer is at least 25, the ball satisfies the relationship A/B≤2.0, where A and B are the deflections of, respectively, the inner core layer and the two-layer core when compressed under specific loading conditions, and the intermediate layer has a higher material hardness than the cover, and the core hardness profile are optimized by the specific conditions. This ball enables mid- to high-level golfers both to achieve even longer distances and to maintain the spin performance on approach shots at a high level.

Claim (Index 1):
A multi-piece solid golf ball comprising a rubber two-layer core consisting of an inner layer and an outer layer, a cover, and at least one intermediate layer between the core and the cover, wherein the inner core layer has a diameter of at least 22 mm, the value obtained by subtracting a center hardness of the inner core layer from a surface hardness of the outer core layer, expressed in terms of JIS-C hardness, is at least 25, the ball satisfies the relationship A/B\u22642.0, where A is the deflection (mm) of the inner core layer when compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf) and B is the deflection (mm) of the two-layer core when compressed under a final load of 1,275 N (130 kgf) from an initial load of 98 N (10 kgf), and the intermediate layer has a higher material hardness than the cover,\n wherein the multi-piece solid golf ball satisfies the conditions:\n C 5\u2212 Cc\u2264Cs\u2212C 15 \n C 10\u2212 C 5\u2264 Cs\u2212C 15 \n C 5\u2212 Cc\u2264C 15\u2212 C 10, and \n 1.5\u2264( Cs\u2212C 10)/( C 10\u2212 Cc )\u22644, \n where Cc is the JIS-C hardness at a center of the core, C5 is the JIS-C hardness at a position 5 mm from the core center, C10 is the JIS-C hardness at a position 10 mm from the core center, C15 is the JIS-C hardness at a position 15 mm from the core center, and Cs is the JIS-C hardness at a surface of the core.
