Colored golf ball
View Patent ↗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.
1. 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 at least one intermediate layer contains a fluorescent dye and/or a fluorescent pigment in an amount ranging from 0.5 part to 10 parts with respect to 100 parts by mass of the resin component, contains a low opaque mass adjusting agent consisting of barium sulfate in an amount ranging from 5 parts to 30 parts with respect to 100 parts by mass of a resin component, and has a density of 1.00 g/cm 3 or more and less than 1.20 g/cm 3 ;
the cover contains titanium oxide in an amount of more than 0.03 parts and a fluorescent dye and/or a fluorescent in an amount ranging from 0.5 parts to 10 parts with respect to 100 parts by mass of a resin component.
2. The colored golf ball according to claim 1 , wherein the golf ball has a color which satisfies the following equations in CIELAB color coordinate system in terms of L*, a*, and b* values
L*<85,a*<−20 or a*>30,b*>10.
3. The colored golf ball according to claim 1 , further comprising at least one paint layer.
4. The colored golf ball according to claim 3 , wherein the at least one paint layer further comprises a luster material.
5. The colored golf ball according to claim 1 , further comprising a first paint layer comprising a luster material and formed on the cover, and a second paint layer formed on the first paint layer, wherein a mark is formed between the first paint layer and the second paint layer.
6. The colored golf ball according to claim 1 , wherein the fluorescent dye and/or the fluorescent pigment has a melting point of 180° C. or less.
7. The colored golf ball according to claim 1 , wherein the cover contains titanium oxide in an amount of 0.05 parts or more.
8. 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,
a cover disposed around the core, and
at least one paint layer formed on the cover,
wherein at least one intermediate layer contains a fluorescent dye and/or a fluorescent pigment in an amount ranging from 0.5 parts to 10 parts with respect to 100 parts by mass of the resin component, contains a low opaque mass adjusting agent consisting of barium sulfate in an amount ranging from 5 parts to 30 parts with respect to 100 parts by mass of a resin component, and has a density of 1.00 g/cm 3 or more and less than 1.20 g/cm 3 ;
the cover contains titanium oxide in an amount of 0.03 parts or more and a fluorescent dye and/or a fluorescent pigment in an amount ranging from 0.5 parts to 10 parts with respect to 100 parts by mass of a resin component; and
the golf ball has a color which satisfies the following equations in CIELAB color coordinate system in terms of L*, a*, and b* values
L*<85,a*<−20 or a*>30,b*>10.
9. The colored golf ball according to claim 8 , wherein the at least one paint layer further comprises a luster material.
10. The colored golf ball according to claim 8 , further comprising a first paint layer comprising a luster material and formed on the cover, and a second paint layer formed on the first paint layer, wherein a mark is formed between the first paint layer and the second paint layer.
11. 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,
a cover disposed around the core, and
at least one paint layer formed on the cover,
wherein at least one intermediate layer contains a fluorescent dye and/or a fluorescent pigment, contains a low opaque mass adjusting agent consisting of barium sulfate in an amount ranging from 5 parts to 30 parts with respect to 100 parts by mass of a resin component, and has a density of 1.00 g/cm 3 or more and less than 1.20 g/cm 3 ;
the cover contains titanium oxide in an amount of 0.03 parts or more and a fluorescent dye and/or a fluorescent pigment in an amount ranging from 0.5 parts to 10 parts with respect to 100 parts by mass of resin component; and
a color difference (ΔE*) between the intermediate layer and the cover is 12 or less in the CIELAB color coordinate system.
12. The colored golf ball according to claim 11 , wherein the intermediate layer and the paint layer have a color difference (ΔE*) of 12 or less in CIELAB color coordinate system.
13. The colored golf ball according to claim 11 , wherein a color difference (ΔE*) between the cover and the paint layer is 12 or less in CIELAB color coordinate system.
