A golf ball includes a composition producing a unique visible effect to enhance a performance parameter of the golf ball. The golf ball includes a color-shifting cover surrounding a core. The color-shifting cover includes a cover material mixed with a colorant. The cover material includes at least one of a thermoset polyurethane, cast urethane, or ionomer material. The colorant includes one or more of a flake, pigment, or dye. The color-shifting cover includes a visible shift in color based on a change in at least one of incidence of light, temperature, or pressure.

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.

A first stamp and a second stamp are printed on the surface of a golf ball such that a transition printed area of the first stamp overlaps a transition printed area of the second stamp to create an overlap printed area between a main printed area of the first stamp and a main printed area of the second stamp. An ink density of the main printed area of the first stamp, an ink density of the main printed area of the second stamp, and an ink density of the overlap printed area are approximately the same after both the first stamp and the second stamp are printed on the surface of the golf ball.

Provided are a golf ball which has a surface that sparkles when exposed to ultraviolet rays even if a naturally derived substance is used as a fluorescent material, and it is environmentally and human friendly, and a resin composition for a cover or a topcoat therefor. A resin composition for a cover or a topcoat of a golf ball of the present invention includes: a resin for a cover or a topcoat; and a plant-derived or alga-derived extract which emits light using an absorbed light as an energy source, as a fluorescent material. In the golf ball of the present invention, the cover or the topcoat is formed by using such a resin composition.

A golf ball includes a core, a cover and a coating layer disposed entirely about an outer surface of the cover. The coating layer is opaque about an entirety of the outer surface of the cover and consists of three regions: a first color region, a second color region, and a transition color region disposed between the first color region and the second color region about an entire circumference of the golf ball. The first color region consists of a spray-painted first color. The second color region consists of a spray-painted second color that is different than the spray-painted first color. The transition color region consists of a combination of the spray-painted first color and the spray-painted second color, wherein said combination produces a transitional color that is a spectrophotometer-measurable different color than both the first and the second colors.

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.

A colored golf ball has improved luxurious appearance without impairing its visibility. The colored golf ball of the present invention includes a core; a cover placed around the core having dimples formed on its surface; and a coating layer placed on top of the cover, in which the coating layer includes a polymer matrix having a bright material dispersed therein, and an L.sub.0 value, which represents an L value in the Lab color system of the colored golf ball before being covered with the coating layer, is 25 or less, and the difference L between the L.sub.0 value and an L.sub.1 value, which represents an L value in the Lab color system of the colored golf ball after being covered with the coating layer, is 5 or more.

Provided is a golf ball having a matte surface with improved visibility. Since the golf ball has a matte surface in comparison with a golf ball having a glossy surface of the related art, the golf ball has an advantage of preventing the golfer from being dazzled caused by reflection of a dimple surface. Since the golf ball has a relatively high luminance value in comparison with a golf ball having a matte surface of the related art, the golf ball has an advantage of being seen to be larger. Since the amount of light remaining in a dimple cover is increased, fluorescent characteristics of a fluorescent material is improved, so that beautiful colors and improved visibility can be achieved. Therefore, it is possible to improve golfers' performance.

An object of the present invention is to provide a golf ball having a high performance as well as the visibility and the fashionable appearance. The present invention provides a colored golf ball having a color other than white and comprising: a core having a center and at least one intermediate layer disposed around the center, and a cover disposed around the core, wherein the cover and at least one of the intermediate layer preferably contain a fluorescent dye and/or a fluorescent pigment.
