Golf balls having a low surface coverage dimple pattern arranged in a tetrahedral layout are disclosed. The dimple pattern has four substantially identical dimple sections. The dimples in each of the four dimple sections have at least three different dimple diameters, including a minimum dimple diameter, a maximum dimple diameter, and an additional (third) dimple diameter, where the additional dimple diameter substantially contributes to the overall surface coverage of the dimple pattern. The resulting dimple pattern has a low dimple surface coverage and high diameter disparities among the dimples, which helps to reduce the flight of the golf ball while providing improved aerodynamic consistency.

An object of the present disclosure is to provide a golf ball having improved flight distance on driver shots and excellent spin performance on approach shots (particularly under the condition that there is grass between the golf ball and the club face) and on middle iron shots. The present disclosure provides a golf ball comprising a spherical core and a cover disposed outside the spherical core, wherein when a center hardness of the spherical core (Shore C hardness), hardnesses at 2.5 mm, 5 mm, 7.5 mm, 10 mm, 12.5 mm and 15 mm points from a center of the spherical core toward a surface of the spherical core (Shore C hardness), and a surface hardness of the spherical core (Shore C hardness) are represented by H0, H2.5, H5, H7.5, H10, H12.5, H15 and Hs respectively, the following relation is satisfied:(H2.5−H10)>(H12.5−H10)>(Hs−H15).

An object of the present disclosure is to provide a golf ball having a small difference in the flight distance on a driver shot when hit at a high head speed and when hit at a low head speed. The present disclosure provides a golf ball comprising a spherical core, an intermediate layer and an outermost cover, wherein when a center hardness Ho (Shore C hardness) of the spherical core, a surface hardness Hs (Shore C hardness) of the spherical core, a hardness difference S=Hs-Ho, a material hardness Hm (Shore D hardness) of the intermediate layer, a material hardness Hc (Shore D hardness) of the outermost cover, a thickness Tc (mm) of the outermost cover, and a total lower volume Vi (mm3) of a plurality of dimples satisfy Vi>365 and (Hc / Tc)×(S×Hm / Vi)≤130.

The sub-functions that define the piecewise function can include, for example, a catenary function and a Gabriel's horn function. A transition between the sub-functions defining the piecewise function is smooth. At least one of the sub-functions can have a non-constant radius of curvature. The golf ball dimple half profile is rotated about the dimple's centroid to create the full dimple profile.

Rubber compositions including sulfonamides, and golf ball cores made from such compositions are disclosed. The type and concentration of components in the composition affect the properties of cores made therefrom, including, for example, coefficient of restitution and compression, and, thus, can be used to produce golf balls having desirable performance characteristics.

The projected pattern can comprise at least one first crest and at least one first trough. The projected pattern can have a periodic function selected from: a sine wave, a sawtooth wave, a triangle wave, or a square wave.

A golf ball includes an assist mark 10 and a guide mark. The assist mark is straight in plan. The guide mark is distorted in plan. The guide mark is in the shape of an arrow as a whole. The guide mark looks straight to a player swinging a golf club. The player moves the head of the golf club along the direction of the guide mark.

To provide a golf ball which achieves a satisfactory carry in time of a full shot not only with a driver (W#1) but also with an iron, is superior in a short game, and also has a good feel at impact and excellent scuff resistance.SOLUTION: A multi-piece solid golf ball has a core, an envelope layer, an intermediate layer and a cover. The core consists of a single layer or plural layers, formed primarily of a base rubber. The core has a diameter of at least 30 mm.The envelope layer consists of two layers of an inner layer and an outer layer. The intermediate layer and the cover each consist of a single layer, formed of a resin material. The surface hardness of the core and respective layer-encased spheres satisfies the formula: core surface hardness<surface hardness of inner envelope layer-encased sphere<surface hardness of outer envelope layer-encased sphere<surface hardness of intermediate layer-encased sphere>ball surface hardness. The Shore C hardness value obtained by subtracting the center hardness from the core surface hardness is 16 or more. The respective layers have thicknesses which satisfy the following relations: cover thickness<intermediate layer thickness; and outer envelope layer thickness<inner envelope layer thickness.SELECTED DRAWING: Figure 1
