    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)

    摘要: The present invention provides a solid golf ball having excellent flying performances, stability upon iron shot and good hit feeling.A solid core 1 comprising an center 1a and an outer shell 1b is coated with a cover 2 to give a three-piece solid golf ball. The center 1a has a diameter of 30.7 to 39.5 mm, a stiffness of 300 to 2,500 kgf/cm.sup.2 and a shore D hardness of 30 to 55. The outer layer core 1b has a thickness of 1.0 to 4.0 mm, a stiffness of 2,500 to 6,000 kgf/cm.sup.2 and a shore D hardness of 55 to 75. The composition of both cores is a butadiene rubber. The cover 2 has a thickness of 0.6 to 2.0 mm, a stiffness of 1,000 to 2,500 kgf/cm.sup.2 and a shore D hardness of 40 to 55. The composition of the cover is an ionomer resin or a mixture of the ionomer resin and a flexible resin.
