Abstract

A golf ball comprising layers that have from 0.05% to 70% by weight of a radio-opaque filler, and wherein the concentration of the radio-opaque filler is measurably different in each layer is disclosed herein. The radio-opaque filler is preferably a compound based on barium, bismuth, tungsten, iodine, or reduced iron.

Claims (15)

1. A golf ball comprising:

a center core comprising a first polybutadiene, a second polybutadiene, a zinc diacrylate, a zinc oxide, a zinc stearate, a peroxide, an organic sulfur, and 0.05% to 70% by weight of radio-opaque filler, wherein the core has a density ranging from 1.1 to 3.5;

an inner mantle layer composed of an ionomer blend and 0.5% to 70% by weight of radio-opaque filler;

an outer mantle layer composed of an ionomer blend and 0.5% to 70% by weight of radio-opaque filler; and

a cover layer disposed over the outer mantle layer, the cover layer is preferably composed of a thermoplastic polyurethane material and 0.5% to 70% by weight of radio-opaque filler, wherein the cover layer has a density ranging from 1.0 to 3.5;

wherein the center core has a concentration of the radio-opaque filler that is measurably different than a concentration of radio-opaque filler in the cover layer;

wherein the radio-opaque filler is an iodine-based compound;

wherein the golf ball has a COR of at least 0.75.

2. A golf ball comprising:

a center core comprising a first polybutadiene, a second polybutadiene, a zinc diacrylate, a zinc oxide, a zinc stearate, a peroxide, an organic sulfur, and 0.05% to 70% by weight of radio-opaque filler, wherein the core has a density ranging from 1.1 to 3.5;

a mantle layer composed of 30 to 50 weight percent of a first ionomer, 30 to 50 weight percent of a second ionomer, 1 to 20 weight percent of an impact modifier, 5 to 25 weight percent of BaSO4, and 0.1 to 1.0 weight percent of a masterbatch, wherein the mantle layer has a density ranging from 0.9 to 1.0; and

a cover layer disposed over the mantle layer, the cover layer is preferably composed of a thermoplastic polyurethane material and 0.5% to 70% by weight of radio-opaque filler, wherein the cover layer has a density ranging from 1.0 to 3.5;

wherein the center core has a concentration of the radio-opaque filler that is measurably different than a concentration of radio-opaque filler in the cover layer;

wherein the radio-opaque filler is an iodine-based compound;

wherein the golf ball has a COR of at least 0.75.
