Abstract: Golf ball comprising a core having a hardness gradient and an outer cover layer having a microhardness gradient and being formed from a thermoset polyurethane material throughout, and having: i) a treated region that is contacted with a thermoset polyurethane microhardness-increasing solution consisting of an isocyanate portion and at least one non-aqueous solvent; and ii) an untreated region that is not contacted with the thermoset polyurethane microhardness-increasing solution. The treated region comprises the isocyanate portion, whereas the untreated region does not comprise the isocyanate portion. Treated region has a microhardness M1 that is greater than microhardness M2 of untreated region to define the outer cover layer positive microhardness gradient ΔM=M1−M2. The treated region may have a depth Dtr that extends inward from the cover outer surface and in some embodiments is less than a thickness of the untreated region. Treated region may alternatively extend from the inner surface toward outer surface.

Abstract: In a multi-piece solid golf ball having a core, a cover and an intermediate layer therebetween, the core, an intermediate layer-encased sphere and the ball have surface hardnesses which satisfy a specific relationship, and the intermediate layer and the cover have thicknesses which satisfy a specific relationship. Also, the core has a hardness profile in which the hardnesses at the core surface, core center, a position 5 mm from the core center, and a position midway between the surface and center of the core satisfy specific relationships. This golf ball, when used by mid- and high-level amateurs, enables the golfer to maintain an adequate distance on shots with a driver and achieve a good distance on iron shots, has a good spin performance on approach shots and has a good feel on impact. In addition, the ball has an excellent scuff resistance when struck with a grooved wedge.

Abstract: A golf ball includes a core having an outer surface, a geometric center, and a soft transition region adjacent to the outer surface. The soft transition region has a thickness of about 4 mm or less and includes about 10 to 45 percent of a trans-polybutadiene isomer. An outer cover layer has a hardness of about 50 Shore M or greater. The core outer surface hardness is greater than the hardness at the geometric center to define a positive hardness gradient of about 12 to 68 Shore C. The core has a secondary gradient quotient, GQ′, of 4 to 13, GQ′ being defined by the equation: G ′ + T 10 × COR where G′ is the positive hardness gradient in Shore C, T is the percent trans-polybutadiene isomer at the core outer surface, and COR is the coefficient of restitution of the core measured at an incoming velocity of 125 ft/.

Abstract: In a multi-piece solid golf ball having a core, an envelope layer, an intermediate layer, and a cover with a plurality of dimples formed thereon, the core is formed primarily of a base rubber, the envelope layer and the intermediate layer are formed primarily of synthetic resin materials, and the cover layer is formed primarily of a urethane material. The relationships between, respectively, the surface hardnesses of the envelope layer-encased sphere and the ball, the thicknesses of the intermediate layer and the cover layer, the deflections of the core and the ball, and the initial velocities of the core and various layer-encased spheres of the ball each satisfy specific conditions. This golf ball makes it possible for amateur golfers, while maintaining a good distance on shots with a driver (W#1), to obtain a good ball controllability on approach shots and moreover experience a soft feel at impact.
