Description

  The present invention relates to a golf ball.

  Golf is a widespread national sport, regardless of age or gender. A golf ball used in a competition has a surface layer formed, for example, by injection molding a resin around the outer periphery of a ball core formed by a winding method. The surface layer is usually white and has a large number of dimples.

  In recent years, instead of the above-mentioned uniform design (white) golf balls, there has been a demand for a golf ball with better design and a design that can easily confirm the falling position of the launched golf ball. Yes. Therefore, it is conceivable that the surface layer is colored instead of white, but simply coloring is not sufficient in terms of visibility from a distance.

  This invention is made | formed in view of the said situation, The subject is providing the golf ball excellent in visibility and design property.

  In order to solve the above problems, a golf ball according to the present invention includes a spherical core, a light reflecting layer formed on the surface of the core so as to cover the core, and a dimple formed on the surface of the light reflecting layer. And a transparent resin layer on which is formed.

  According to the golf ball having such a configuration, the light reflecting layer is formed so as to cover the core, and the transparent resin layer is further formed on the outer peripheral surface thereof. Therefore, the light incident through the transparent resin layer is reflected by the light reflection layer, and can give a sparkle. Therefore, it is easy to find a golf ball even from a distance, and the design can be improved.

  The transparent resin layer according to the present invention is preferably colored to such an extent that light can be transmitted. By coloring, the design can be further enhanced, and the glittering feeling can be further improved. Coloring can be performed by blending a dye or a pigment with the resin.

  The light reflecting layer according to the present invention is preferably a metallic colored layer, and the transparent resin layer is preferably a colorless transparent resin layer. Since the colored layer is inside the colorless transparent resin layer, it is expected that, for example, fading due to bleed-out can be suppressed as compared with a configuration in which a dye or pigment is added to the transparent resin layer.

Sectional view showing internal structure of golf ball

  A preferred embodiment of a golf ball according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing the internal structure of a golf ball.

<First Embodiment>
In FIG. 1, the golf ball includes a spherical core 1, a light reflecting layer 2 covering the core 1, and a transparent resin layer 3 formed outside the light reflecting layer 2. A large number of dimples 3 a are formed on the surface of the transparent resin layer 3.

  As the core 1, a solid core or a thread wound core for a normal golf ball is used. For the colorless transparent resin layer 3, an ionomer resin (for example, trade name “Surlin” manufactured by DuPont) is preferably used. The ionomer resin is excellent in transparency, toughness, wear resistance, and the like, and is suitable as a material for golf balls.

  The light reflecting layer 2 can be a metallic layer having a metallic color tone. The metallic layer can be formed, for example, by a coating layer containing an aluminum pigment, a film formed by vapor deposition of aluminum, or printing having a metallic color tone. Thereby, it can be set as a silvery reflection layer.

  Since the transparent resin layer 3 is formed on the outer peripheral surface of the light reflecting layer 2, the light passes through the transparent resin layer 3 and is reflected by the surface of the light reflecting layer 2. By using a metallic layer, when light is reflected, it is possible to obtain a brilliant visibility. Thereby, the position of the golf ball can be recognized from a distance, and the design can be improved.

  The transparent resin layer 3 may be colorless and transparent, but by adding an appropriate amount of a dye or pigment, in addition to the glittering visibility, the design can be further improved by coloring. As a color in the case of coloring, the color which has saturation, such as pink, orange, green, yellow, purple, is illustrated.

<Second Embodiment>
Next, the second embodiment will be described. The structure is similar to that of the first embodiment, and will be described with reference to FIG. In FIG. 1, a golf ball includes a spherical core 1, a metallic colored layer 2 (corresponding to a light reflecting layer) covering the core 1, and a colorless transparent resin layer 3 formed outside the metallic colored layer 2. Composed. A large number of dimples 3 a are formed on the surface of the colorless and transparent resin layer 3. About the core 1 and the colorless and transparent resin layer 3, it can be made into the same material as 1st Embodiment.

  Since the metallic colored layer 2 is formed inside the colorless and transparent resin layer 3, the metallic colored layer 2 is visually recognized through the colorless and transparent resin layer 3. Specific examples of the configuration of the metallic colored layer 2 include the following various configuration examples. Examples of coloring include colors having a saturation such as pink, orange, green, yellow, and purple. Since it is a metallic layer, it functions as a light reflection layer and can give a brilliant visibility.

  The first is a method of forming a metallic coating film on the surface of the core 1. For example, it can be formed by combining a coating layer containing an aluminum pigment and a coating layer containing an interference mica pigment. As a result, it is possible to add color to the glittering metallic.

  The second is a metallic gloss film. For example, a film formed by vapor-depositing aluminum or the like on one side of a transparent film previously colored in a predetermined color can be used. Alternatively, it is possible to use a transparent film having a colored layer laminated on one side of a transparent film with a light-transmitting metallic luster layer interposed therebetween. Or the multilayer sheet which laminated | stacked the transparent layer which mixed the metal powder in the dispersed state in the transparent resin, and the colored resin sheet layer can be used.

  The third is a method of forming by printing. For example, an ink-jet ink using metal colloid-derived metal fine particles as a colorant can be used.

  Three examples of the metallic coloring layer 2 have been illustrated, but the present invention is not limited to this, and various modifications can be considered. In any case, according to the above configuration, the colorless and transparent resin layer 3 as the outermost layer is not colored, and the metallic colored layer 2 inside thereof is colored. Therefore, a phenomenon such as bleed out, which has been a problem in the past, can be suppressed, and the same color can be maintained for a long time.
