Golf ball comprising core; casing layer; cover layer; and plurality of outer coating layers. Casing layer comprises an ionomer blend of at least one ionomer and a color concentrate resin that is included in an amount of 3-10 wt. % of the ionomer blend. Cover layer is transparent and comprises thermoplastic/thermoset urethane composition. First outer coating layer is adjacent to cover layer and comprises clear water-borne or solvent-borne primer; and second outer coating layer is adjacent to first outer coating layer and comprises gold pearl primer, white sparkle primer, or combination thereof; third outer coating layer is adjacent to second outer coating layer and comprises a clear topcoat. Alternatively, second outer coating layer comprises matte topcoat, clear glossy topcoat, or combination thereof. In all embodiments, first outer coating layer and/or second outer coating layer may be colorless.

A golf ball of the present disclosure includes an inner ball and a cover layer that covers the outer surface of the inner ball and includes an outer surface with dimples. The inner ball includes an inner layer, which includes an outer surface with a recess, and an inner film that covers only the surface of the recess on the outer surface of the inner layer. The inner layer and the inner film are different colors from each other, and the cover layer is transparent or semi-transparent. Peeling of the film can be suppressed in the golf ball.

An object of the present invention is to provide a golf ball having excellent color development stability. The present invention provides a golf ball comprising a core and a cover covering the core, wherein the cover is formed from a resin composition containing a first base resin and a fluorescent pigment, and the fluorescent pigment has a number-based cumulative median size of 2.5 μm or more.

Golf ball comprising one or more layers and/or indicia formed from a fluorescent composition comprising: a base polymer; and a colorant; wherein the colorant is a small-molecule ionic isolation lattice formed from one or more fluorescent dye and one or more cyanostar macrocycles. The one or more fluorescent dyes may include at least one dye selected from xanthenes, oxazines, styryls, cyanines, trianguleniums, or mixtures thereof. The colorant may be a dispersion of the small-molecule ionic isolation lattice in a carrier medium or a powder. In particular embodiments, at least one of the one or more layers is a cover layer and/or a coating layer.

Golf balls having multi-layered covers, wherein at least one of the cover layers is substantially transparent, are provided. The cover includes an inner cover layer made of an ionomer composition; an intermediate cover layer made of an aromatic polyurethane composition; and outer cover layer made of an aliphatic polyurethane composition, wherein the total thickness of the multi-layered cover is no greater than 0.110 inches. In one version, the outer cover layer is substantially transparent and the underlying intermediate cover layer is colored. In another version, both the outer and intermediate cover layers are substantially transparent. Light-reflective fillers such as pearlescent pigments, glitter, and metallics may be added to the cover layers. The resulting ball has pleasing decorative effects.

A golf ball of the present disclosure includes an inner ball and a cover layer that covers the outer surface of the inner ball and includes an outer surface with dimples. The inner ball includes an inner layer, which includes an outer surface with a recess, and an inner film that covers only the surface of the recess on the outer surface of the inner layer. The inner layer and the inner film are different colors from each other, and the cover layer is transparent or semi-transparent. Peeling of the film can be suppressed in the golf ball.

In a golf ball having a core, a cover, at least one intermediate layer therebetween, and a coating layer on the cover, the cover is formed of a transparent or translucent resin composition and the intermediate layer is formed of a resin composition. The sphere consisting of the core encased by the intermediate layer has specific lightness and chroma values in the Lab color space. The coating layer is composed of one or more layer, at least one of which contains an effect pigment having polarizing properties. Markings are provided inside of the coating layer and have a specific L value. During use, the ball retains a visual to familiarity close to that of a white ball. Up close, it is clearly discernible from a white ball; from a distance, it appears white and is highly visible.

Golf ball comprising core; casing layer; cover layer; and plurality of outer coating layers. Casing layer comprises an ionomer blend of at least one ionomer and a color concentrate resin that is included in an amount of 3-10 wt.% of the ionomer blend. Cover layer is transparent and comprises thermoplastic/thermoset urethane composition. First outer coating layer is adj acent to cover layer and comprises clear water-borne or solvent-borne primer; and second outer coating layer is adjacent to first outer coating layer and comprises gold pearl primer, white sparkle primer, or combination thereof; third outer coating layer is adjacent to second outer coating layer and comprises a clear topcoat. Alternatively, second outer coating layer comprises matte topcoat, clear glossy topcoat, or combination thereof. In all embodiments, first outer coating layer and/or second outer coating layer may be colorless.

In a golf ball comprising a core, a cover layer, an intermediate layer between the core and the cover layer, the cover layer is formed of a resin material composed primarily of polyurethane or polyurea, a sphere obtained by encasing the core with the intermediate layer (intermediate layer-encased sphere) has a lightness (Li value) in the L*a*b* color space of at least 25 on its surface, and the cover layer has a visible light transmittance of at least 0.6%. The golf ball has a surface with a distinctive aesthetic appearance and retains both a good spin performance and a good scuff resistance, making it useful as a ball for professional and skilled amateur golfers.
