    Abstract: The present invention is directed to golf balls having a resilient inner core and outer core made of a material substantially free of fillers. The invention also encompasses golf balls wherein the inner and outer cores are not made of a thermoplastic material. The invention encompasses golf balls having an inner core, an outer core, an inner cover, and an outer cover wherein the inner core is encased by an outer core wherein the inner core has a volume greater than the outer core, inner cover, or outer cover and the inner core is made of a material substantially free of fillers. The volume relationship of the inner core (V12), outer core (V14), inner cover (V16), and outer cover (V18) is represented by the mathematical relationship: V12>2.5(V14+V16+V18), wherein V14≧V18≧V16. Also, the inner core has a specific gravity &rgr;12, the outer core has a specific gravity &rgr;14, the inner cover has a specific gravity &rgr;16, and the outer cover has a specific gravity &rgr;18, wherein the relationship between the specific gravities is expressed by the mathematical expression: &rgr;16≧&rgr;18≧&rgr;14≧&rgr;12.

    Abstract: A multi-piece golf ball includes a rubbery elastic core, a cover having a plurality of dimples on the surface thereof, and at least one intermediate layer between the core and the cover. The intermediate layer is composed of a resin material which is harder than the cover. The elastic core has a hardness which gradually increases radially outward from the center to the surface thereof. The center and surface of the elastic core have a hardness difference of at least 18 JIS-C hardness units. This construction and combination of features improve the distance of the ball when struck with a driver, provide the ball with excellent spin characteristics and thus good controllability on approach shots, and gives the ball a good feel on impact, enabling the ball to meet the high expectations of skilled golfers.

    Abstract: The invention provides a multi-piece solid golf ball having improved flight performance, controllability and good shot feel at the time of hitting. The multi-piece solid gold ball has a core having at least one layer, an intermediate layer formed on the core, and a cover covering the intermediate layer. When thickness of the intermediate layer is represented as X (mm) and JIS-C hardness of the intermediate layer is represented as Y, then X is 0.3 to 1.5 mm, X and Y have a correlation represented 10X+55≦Y≦10X+75, and the JIS-C hardness of the cover is 70 to 93.
