摘要: A golf ball has a core, and a cover for covering the core. The cover contains 0.5 to 10 parts by mass of a titanium oxide relative to 100 parts by mass of a base resin composing the cover, and the titanium oxide is surface-treated with an oxide including at least one element selected from the group consisting of aluminum, silicon, zinc, zirconium, tin, and cerium, and/or a hydrate thereof The golf ball has less or no discoloration or degradation with time, and has superior weatherability.

摘要: The present invention provides a golf ball which does not cause poor impact resilience but provides long distance carry as well as good hit feeling, and keeps controllability nearly similar to balata covered thread wound golf balls. The present invention provides a golf ball which comprises a core and a cover for covering the core, wherein the cover comprises, as base component, a mixture of a sulfonate-type ionomer of which a polymer chain contains an elastomeric portion having rubber resilience and has a sulfonic group neutralized by a metallic ion, and a carboxylate type ionomer which is a copolymer of at least .alpha.-olefin and .alpha.,.beta.-unsaturated carboxylic acid of which a carboxyl group is neutralized by a metallic ion.

摘要: The objective of the present invention is to bring hit feeling of two-piece balls closer to that of thread-wound golf balls. The two-piece golf ball of the present invention comprises a core formed from a rubber composition comprising a base rubber, a co-crosslinking agent and an organic peroxide, and a cover covering the core, wherein said core has the following hardness distribution when measured by a JIS-C hardness meter;(1) hardness at a center: 58-73(2) hardness at 5-10 mm from the center: 68-78(3) hardness at 15 mm from the center: 76-88(4) surface hardness: 78-88(in the hardness distribution, hardness (2) is substantially constant being within the above range, of which tolerance is within .+-.3 and the other values satisfy the relation of (1)
