    Abstract: An object of the present invention is to provide a golf ball striking a good balance between a flight distance on driver shots and a spin rate on approach shots, and excellent in stain resistance and a shot feeling. The present invention provides a golf ball comprising an intermediate layer, a cover, and a paint film, wherein a base resin of the paint film is a polyurethane obtained by a reaction between a polyisocyanate composition and a polyol composition containing a urethane polyol including a polyether diol with a number average molecular weight ranging from 800 to 3000 as a constituent component, and the golf ball satisfies the following requirements; Mp≦200×X−75 Mp≦100 Mm−Mc>100 Tm>Tc>Tp (Tm×Mm)/(Tc×Mc)>7.5 (Tc×Mc)/(Tp×Mp)>2.4. [Mp, Mm and Mc represent 10% modulus (kgf/cm2) of the paint film, intermediate layer and cover, respectively; Tp, Tm and Tc represent thicknesses (mm) of the paint film, intermediate layer and cover, respectively; and X represents a molar ratio (NCO/OH) of a NCO group in the polyisocyanate composition to a OH group in the polyol composition.]

    Abstract: A golf ball includes a spherical core and a cover. The core includes an inner core, a mid core, and an outer core. A hardness H(C) is equal to or greater than a hardness H(B). A hardness H(E) is equal to or greater than a hardness H(D). An angle α is calculated by (Formula 1) from a thickness Y (mm) of the mid core, the hardness H(C), and the hardness H(D). An angle β is calculated by (Formula 2) from a thickness Z (mm) of the outer core, the hardness H(E), and the hardness H(F). Each of the angle α and a difference (α−β) between the angles α and β is equal to or greater than 0°. The golf ball has excellent flight performance upon a shot with a driver. α=(180/n)*a tan [{H(D)−H(C)}/Y]  (Formula 1) β=(180/n)*a tan [{H(F)−H(E)}/Z]  (Formula 2)
