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.

An object of the present invention is to provide a golf ball having high visibility and excellent orientation at shot. The present invention provides a golf ball comprising a core and a cover disposed outside of the core, wherein a surface of the golf ball has a first region with a first color and a second region with a second color, the first color has hue H1 represented by H value in HSL color space, the second color has hue H2 represented by H value in HSL color space, and the H1 and the H2 satisfy the following mathematical formula (1):

60<|H1H2|<300 (1).

An object of the present invention is to provide a golf ball having high visibility and little uncomfortableness at shot. The present invention provides a golf ball comprising a core and a cover disposed outside of the core, wherein a surface of the golf ball has a first region with a first color and a second region with a second color, the first color has hue H1 represented by H value in HSL color space, the second color has hue H2 represented by H value in HSL color space, and the H1 and the H2 satisfy a specific mathematical formula.

A golf ball core composition is disclosed herein that includes a base rubber, as well as a filler that is comprised of a plant-based, organic material. In one example, the plant-based organic material can include hulls, such as soybean hulls.

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 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 coating free, finished golf ball and a method of forming a coating free, finished golf ball are disclosed herein. The golf ball has an outermost surface defined exclusively via the cover. The cover disclosed herein can be formed from a polyurethane, polyurea, or hybrid of polyurethane-polyurea, in some examples.

A color coating solution is produced by dispersing a nano-color pigment and a metallic gloss pigment into a polymer resin, and the solution is coated and molded on a cover layer having a color similar to that of the color coating solution. Since the pigment composition is different between the cover layer and the color coating layer, internal shieldability is improved. As a result, a dark color or uneven surface of the core, mantle, or cover is not exposed, so that a surface defect rate can be reduced. Since both the nano-color pigment and the metallic gloss pigment are used in the color coating layer, the metallic gloss and the color are exhibited in a single layer. Therefore, it is possible to provide natural metallic gloss without a strange texture feeling.

A golf ball printing system has a support mechanism configured to hold a golf ball. The golf ball printing system also has a motion device configured to rotate the golf ball about an axis of rotation and a rotation control device configured to vary the axis of rotation. The golf ball printing system additionally has a printing device having a marking tool configured to remain stationary while applying marking material to the golf ball while the golf ball is held in the support mechanism. The motion device is configured to rotate the golf ball while the marking tool applies marking material to the golf ball to produce a marking pattern on the golf ball.

A golf ball includes a core, a cover layer, and a chromogenic polymer incorporated into at least one of the cover layer or a coating layer applied to the cover layer. The chromogenic polymer causes the golf ball to exhibit a color-shift effect upon application of an external stimulus. The color-shift effect can be measured as a deltaE of greater than 2 when the external stimulus is within a target range. The external stimulus may be different depending on the type of chromogenic polymer, and, as a result, the target range depends on the type of external stimulus.
