摘要： A golf ball includes at least a core, an inner cover, and an outer cover. The inner and outer covers are of different colors. A portion of the inner cover penetrates the outer cover and is exposed to the outside on the surface of the golf ball. The exposed portion constitutes a mark portion on the surface of the golf ball. Further, an auxiliary layer is provided in contact with the inner cover. The auxiliary layer has a color different from those of the inner and outer covers and has an end surface which is exposed to the outside on the surface of the golf ball within the mark portion. Either the inner cover or the auxiliary layer completely covers the core.

摘要： A method of manufacturing a golf ball is disclosed. A cover is molded through use of either a thermoplastic resin having a group capable of reacting with an isocyanate group or a thermoplastic resin containing a compound having two or more groups capable of reacting with an isocyanate group. Subsequently, a polyisocyanate compound is caused to permeate into the surface layer of the cover to thereby cause the reaction between the polyisocyanate compound and the group(s) capable of reacting with the isocyanate group. As a result, a modified layer having excellent properties is formed at the surface of the cover formed from thermoplastic resin. In this case, a non-yellowing polyurethane resin is preferably used as the thermoplastic resin having a group capable of reacting with an isocyanate group, and 4,4-diphenylmethane diisocyanate (MDI) is preferably used as the polyisocyanate compound.

摘要： A golf ball is molded in a mold comprising a pair of removably joined mold sections. The golf ball has a plurality of dimples, the dimples being arranged in a polyhedral arrangement. The golf ball is free of a great circle which does not intersect with the dimples. The dimples (D2) lying across the parting line (P) between the mold sections, except for the dimples (D1) whose center lies on the parting line, are shifted upward or downward from the parting line or reduced in diameter so that these dimples are located outside the parting line (P). The dimple surface coverage is at least 71%. A golf ball having high symmetry and excellent flight performance can be prepared using a simple mold.

摘要： A golf ball has a coating layer formed by dispersion coating at the surface portion thereof. For example, a two-piece golf ball is produced by enclosing a solid core with a cover material; forming, by dispersion coating, a white coating layer made of a thermoplastic resin on the surface of the cover material; conducting mark stamping on the coating layer; forming, by dispersion coating, a transparent coating layer made of a thermosetting resin as an outermost layer; and then conducting dimple processing. The coatings have thicknesses in the range of 15-250 .mu.m. Even when the coating layer at a surface portion is formed relatively thick, the coating layer allows the dimples to be precisely shaped and sharp edged and can be given sufficient durability and functions to improve travel properties, spin properties, and feel on impact. The coating layer is formed by dispersion coating using a water system emulsion which is prepared by dispersing a resin powder in water and wherein the resin powder has a gram size 1-3 .mu.m.

摘要： In a golf ball, dimples are arranged in its spherical surface such that a great circle which does not intersect with the dimples is not drawable on the ball surface, thereby preventing any drop of symmetry caused by the presence of a seam line. The dimples are further arranged such that a percent dimple volume VR given as (B/A).times.100% is in the range: 0.6%
