Golf balls having unique effect pigments in one or more layers
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.
1. A golf ball, comprising:
a color-shifting cover surrounding a core,
wherein the color-shifting cover comprises a cover material mixed with a colorant,
wherein the cover material comprises at least one of a thermoset polyurethane, cast urethane, or ionomer material,
wherein the colorant comprises one or more of a flake, pigment, or dye that shift between at least three colors,
wherein the color-shifting cover changes color based on a change in at least one of incidence of light, temperature, or pressure; and
wherein the colorant comprises a chemical composition including:
a. PLA;
b. cyanidin chloride;
c. dodecyl gallate; and
d. hexadecanoic acid.
2. The golf ball of claim 1 , wherein the cover material is transparent.
3. The golf ball of claim 1 , wherein the cover material is white.
4. The golf ball of claim 1 , wherein the cover material is non-white.
5. The golf ball of claim 1 , wherein the colorant comprises a plurality of flakes mixed with the cover material, wherein the plurality of flakes exhibit a reversible color change property.
6. The golf ball of claim 5 , wherein the flakes are thermochromic.
7. The golf ball of claim 6 , wherein the color-shifting cover produces a linear color shift such that a first temperature change results in a first delta E color change effect, and a second temperature change that is twice the first temperature change results in a second delta E color change effect that is twice the first delta E color change effect.
8. The golf ball of claim 7 , wherein the color-shifting cover produces a color shift including a change color resulting in a delta E of at least 2 when comparing values measured before and after a 2° C. temperature change, at least 5 when comparing values measured before and after a 5° C. temperature change, and at least 10 when comparing values measured before and after a 10° C. temperature change.
9. The golf ball of claim 5 , wherein the flakes are photochromic.
10. The golf ball of claim 9 , wherein the color-shifting cover produces a color shift including a change color resulting in a delta E of at least 1 when comparing values measured before and after exposure to a threshold amount of light in the 400-700 nm range.
11. The golf ball of claim 5 , wherein the flakes are at least one of fluorescent, holographic, iridescent, or pearlescent.
12. The golf ball of claim 8 , wherein the at least three colors include at least three of blue, green, gold, red, purple, orange, violet, yellow, and white.
13. A golf ball, comprising:
a color-shifting cover surrounding a core,
wherein the color-shifting cover comprises a cover material mixed with a colorant,
wherein the cover material comprises at least one of a thermoset polyurethane, cast urethane, or ionomer material,
wherein the colorant comprises one or more of a flake, pigment, or dye,
wherein 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, and
wherein the colorant comprises a chemical composition including:
a. PLA;
b. cyanidin chloride;
c. dodecyl gallate; and
d. hexadecanoic acid.
