    摘要: A center of a golf ball is formed from a composition having a flexural modulus from 150-450 MPa, a maximum loss factor (tan δ) between −20 and 0° C. of 0.08 or less, a rebound resilience of 55% or more, and a slab hardness ranging from 40-60 in Shore D hardness. The center composition includes, as a resin component, 30 to 70 mass % of (A) a modified polyester elastomer having a Shore A hardness of 95 or less; 70-30 mass % of (B) a binary ionomer resin having a Shore D hardness of 65 or more, a flexural modulus of 300 MPa or more, and a melt flow rate (190° C., 2.16 kg) of 1.0 g/10 min or more; and 0-50 mass % of (C) a thermoplastic resin other than (A) and (B) components (provided that a total content of (A), (B), and (C) components is 100 mass %).

    摘要: An object of the present invention is to provide a golf ball resin composition containing an ionomer resin with an excellent resilience and fluidity. Another object of the present invention is to provide a golf ball using an ionomer resin for an intermediate layer, with an excellent shot feeling, durability and resilience. The present invention provides a golf ball resin composition comprising (A) an ionomer resin consisting of a metal ion-neutralized product of a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester; (B) a binary copolymer composed of an olefin and an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and/or a ternary copolymer composed of an olefin, an α,β-unsaturated carboxylic acid having 3 to 8 carbon atoms and an α,β-unsaturated carboxylic acid ester, and (C) a zinc compound, wherein a content ratio ((A)/(B)) of (A) component to (B) component ranges from 50/50 to 80/20 in a mass ratio and a content of (C) component ranges from 0.1 part to 20 parts with respect to 100 parts by mass of a sum of (A) component and (B) component, and the golf ball resin composition has a melt flow rate (190° C., 2.16 kg) of 5 g/10 min or more.

    摘要: In a golf ball composed of a core, a cover of at least one layer that encloses the core, and a plurality of dimples on an outermost layer of the cover, at least one constituent element contains from 0.5 to 30 parts by weight of one or more rare-earth oxide composed of a single rare-earth element, or a rare-earth mixed oxide composed of a plurality of rare-earth elements mixed in a desired ratio, per 100 parts by weight of a base material. Unlike ordinary golf balls, the golf ball of the invention has a visibility which differs under display or indoor light as opposed to outdoors, and is also very fashionable.
