Disclosed is a photoluminescent golf ball with a one- or multi-piece
structure, which comprises an encapsulated photoluminescent composition.
The golf ball is clearly visualized at night and under overcast
conditions, so that it can be easily found where it lands after tee shots
or fairway shots. Additionally, the golf ball has excellent mechanical
properties including surface smoothness, driver distance and strength,
and offers improved luminescent properties including brightness and decay
luminance. Additionally, the photoluminescent pigment has better physical
and chemical compatibility with constituent materials of a golf ball,
providing a more durable ball than is achieved with conventional
photoluminescent pigments.
