Abstract
Official abstract text for this publication.
A golf ball according to the present invention includes a spherical core, a cover member including at least one layer that covers the core, and at least one coating layer that covers the cover member constituting an outermost layer. A plurality of dimples are formed in the cover member constituting the outermost layer. Roughness is formed on the surface of the coating layer. A maximum height Rz and an arithmetic average roughness Ra of the surface of the coating layer satisfy a relationship Rz≥Ra×6.0. The coating layer contains a lustrous material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A golf ball comprising: a spherical core; a cover member including at least one layer that covers the core; and two or more coating layers that cover the cover member constituting an outermost layer, wherein a plurality of dimples are formed in the cover member outermost layer, the coating layers surface has a roughness formed thereon, a maximum height Rz and an arithmetic average roughness Ra of the surface of the coating layers satisfy a relationship Rz≥Ra×6.0, and each of the coating layers contains the same type of lustrous material or a different type of lustrous material. 2. The golf ball according to claim 1 , wherein the lustrous material has a particle diameter of 1 μm or more and 125 μm or less. 3. The golf ball according to claim 1 , wherein the lustrous material has a particle size distribution width of 115 μm or less. 4. The golf ball according to claim 1 , wherein the arithmetic average roughness Ra is 0.5 μm or more. 5. The golf ball according to claim 1 , wherein the maximum height Rz is 4.0 μm or more.
