Abstract
PURPOSE: To provide a billiard ball producing no crack and keeping good surface luster during long time use.
CONSTITUTION: In order to provide a billiard ball producing no crack and keeping good surface luster during long time use, unsaturated polyestel resin consisting of unsaturated polyester and bridging agent of hypoallylphthalate, hypoallylinsophthalate or the like, hardening agent of t-butylperbenzoate, zigmilperoxide or the like, and inorganic filling agent of melamine-treated pulp and calmium carbonate, clay, silica, kaolin or the like, are combined. An original rough ball is formed by extrusion molding and machined into the billiard ball. Average diameter of particles of the inorganic filling agent should be less than 1 mμ preferably.
