A SPORTS BALL

摘要

A phosphorescent sports ball, particularly a golf ball and a tennis ball, is disclosed in which a phosphorescent pigment is added to a plastics component of the ball. The adding can be by way of incorporation within the plastics material or the dyeing of plastics in fibrous form. Prior art phosphorescent balls were painted and thus subject to scuffing. The preferred pigment is ZnS:Cu.
