Abstract: In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)null100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.

Abstract translation: 在包括弹性实心芯和树脂盖的固体高尔夫球中，该盖具有50-85的JIS-C硬度，并且规定球接收干燥状态下的旋转速率S1（rpm），旋转速度S2 当用具有8铁或更高的杆的短铁敲击时，处于湿润状态（rpm），旋转保留百分数：（S2 / S1）×100为至少47％。 用短铁击球时的旋转敏感性在干燥状态或晴朗的天气下不会降低，即使在湿润状态或雨天也不会明显降低。 球具有如此高的性能，使得球按预期行进一段距离，立即停在绿色上，易于控制，因此适合专业和业余的低障碍高尔夫球手。
