<p><P>PROBLEM TO BE SOLVED: To provide a golf ball, whose carry is fine adjusted without sacrificing elasticity, durability, spin and feeling. <P>SOLUTION: Disclosed herein is a golf ball comprising a core, a cover and a velocity reduced layer disposed there between, wherein the velocity reduced layer reduces the coefficient of restitution of the ball by at least 0.005 and a loss tangent in the frequency under 100 Hz of the velocity reduced layer ranges from 0.01 to 100. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
