Abstract
Official abstract text for this publication.
A golf ball that enhances flight performance is provided. A golf ball according to the present invention includes a spherical core, at least one cover member that covers the core, and a coating layer that covers the cover member configuring the outermost layer. A plurality of dimples are formed in the cover member configuring the outermost layer. The thickness of the coating layer is 5.0 μm or more. Roughness is formed on the surface of the coating layer after coating the cover member configuring the outermost layer. The maximum height Rz and the arithmetic average roughness Ra of the surface of the coating layer satisfy the relationship Rz≧Ra×6.0.
First claim
Opening claim text (preview).
1 . A golf ball comprising: a spherical core; at least one cover member that covers the core; and a coating layer that covers the cover member configuring an outermost layer, wherein a plurality of dimples are formed in the cover member configuring the outermost layer, the thickness of the coating layer is 5.0 μm or more, roughness is formed on a surface of the coating layer after coating the cover member configuring the outermost layer, and an arithmetic average roughness Ra of the surface of the coating layer is 0.5 μm or more. 2 . The golf ball according to claim 1 , wherein the maximum height Rz is 4.0 μm or more. 3 . The golf ball according to claim 1 , wherein the roughness of the coating layer is formed by spraying particles. 4 . The golf ball according to claim 3 , wherein an average particle diameter of the particles is 50 μm or more. 5 . The golf ball according to claim 1 , wherein the roughness of the coating layer is formed by a metal mold in which roughness is formed on an inner wall surface of a cavity being pressed onto the coating layer obtained by coating the cover member. 6 . A method for producing a golf ball comprising: forming a spherical core; covering the spherical core with at least one cover member and forming a plurality of dimples in the cover member configuring an outermost layer; covering the cover member configuring the outermost layer with a coating layer; and forming roughness on the coating layer, wherein an arithmetic average roughness Ra is 0.5 μm or more. 7 . The method for producing golf ball according to claim 6 , wherein the maximum height Rz is 4.0 μm or more. 8 . The method for producing golf ball according to claim 6 , wherein the roughness of the coating layer is formed by spraying particles. 9 . The method for producing golf ball according to claim 8 , wherein an average particle diameter of the particles is 50 μm or more. 10 . The method for producing golf ball according to claim 6 , wherein the roughness of the coating layer is formed by a metal mold in which roughness is formed on an inner wall surface of a cavity being pressed onto the coating layer obtained by coating the cover member.
