<p><P>PROBLEM TO BE SOLVED: To provide a golf ball provided with both of soft feeling and a flying distance. <P>SOLUTION: A composite for golf ball formation comprises: polyurethane gel composite particles and at least one kind of base material selected from a group of synthetic resin and an elastomer. In the polyurethane gel composite particles, the surface of three-dimensionally cross-linked polyurethane gel particles consisting of a polyisocyanate compound and a compound having active hydrogen having no polyethelene oxide group, at least either of which has three organic functions, is covered with poly urea colloid particles precipitated from a poly urea colloid nonaqueous solvent. At least one layer of this multi-piece golf ball is formed using the composite. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
