The present invention provides a coated golf ball which suppresses sagging of the paint at the dimple edge after coating, maintains original flying characteristics which the dimple shape possesses, and provides excellent coating appearance. The coated golf ball of the present invention comprises a golf ball body and a paint layer formed thereon, wherein said paint layer is formed from a paint which comprises internally-crosslinked polymer gel fine particles dispersed therein.
摘要:
Polymers of one or more radical polymerisable monomers which polymer has pendant groups bearing a centre of permanent positive charge and other pendant groups capable of stably binding the polymer to a surface are useful in the treatment of surfaces to render them biocompatible. The polymers may contain pendant groups which bind the polymer to a surface by physisorption, covalent bonding or ionic interactions. Additionally reactive groups in the polymer may serve as points for attachment of ligands to the polymer when coated on a surface.
