Multi-piece solid golf ball

Abstract

The present invention provides a multi-piece solid golf ball, which is superior in flight distance, shot feel and controllability. The present invention relates to a multi-piece solid golf ball comprising a core consisting of a center and an intermediate layer formed on the center, and a cover covering the core, wherein the center has a deformation amount when applying from an initial load of 98 N to a final load of 1275 N of 2.7 to 4.5 mm, the intermediate layer has a thickness of 0.5 to 2.0 mm and a hardness in Shore D hardness of 65 to 85, and the cover has a thickness of 0.3 to 1.5 mm and a hardness in Shore D hardness of 30 to 55.

What is claimed is:  
     
         1 . A multi-piece solid golf ball comprising a core consisting of a center and an intermediate layer formed on the center, and a cover covering the core, wherein 
 the center has a deformation amount when applying from an initial load of 98 N to a final load of 1275 N of 2.7 to 4.5 mm,    the intermediate layer has a thickness of 0.5 to 2.0 mm and a hardness in Shore D hardness of 65 to 85, and    the cover has a thickness of 0.3 to 1.5 mm and a hardness in Shore D hardness of 30 to 55.    
     
     
         2 . The multi-piece solid golf ball according to  claim 1 , wherein the intermediate layer is formed from thermoplastic resin other than ionomer resin as a main component.  
     
     
         3 . The multi-piece solid golf ball according to  claim 1 , wherein the cover is formed from polyurethane-based thermoplastic elastomer as a main component.  
     
     
         4 . The multi-piece solid golf ball according to  claim 1 , wherein the polyurethane-based thermoplastic elastomer is formed by using cycloaliphatic diisocyanate.
