The core unit is made from a rubber composition which includes a rubber material, a halogenated organo-sulfur compound, and a phosphorus-containing material. The phosphorus-containing material is selected from the group consisting of metal phosphate, polyphosphate, polyphosphoric ester, phosphonate, phosphate-modified polyester, and combinations thereof. The cover unit is made from a thermoplastic polyurethane composition. ## Claims ### Claim 1 A golf ball, comprising: a core unit made from a rubber composition which includes a rubber material, a halogenated organo-sulfur compound, and a first phosphorus-containing material selected from the group consisting of metal phosphate, polyphosphate, polyphosphoric ester, phosphonate, phosphate-modified polyester, and combinations thereof; and a cover unit enclosing said core unit and made from a thermoplastic polyurethane composition, wherein in said rubber composition, said first phosphorus-containing material is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said rubber material. ### Claim 2 (depends on 1) The golf ball according to claim 1, wherein in said rubber composition, said halogenated organo-sulfur compound is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said rubber material. ### Claim 3 (depends on 1) The golf ball according to claim 1, wherein in said rubber composition, said halogenated organo-sulfur compound is selected from the group consisting of 2-chlorothiophenol, 3-chlorothiophenol, 4-chlorothiophenol, pentachlorothiophenol, a salt of pentachlorothiophenol, and combinations thereof. ### Claim 4 (depends on 1) The golf ball according to claim 1, further comprising an intermediate layer unit which is disposed between said core unit and said cover unit and which encloses said core unit, said intermediate layer unit being made from an ionomer composition which includes an ionomer. ### Claim 5 (depends on 4) The golf ball according to claim 4, wherein said ionomer composition further includes a second phosphorus-containing material selected from the group consisting of metal phosphate, polyphosphate, polyphosphoric ester, phosphonate, phosphate-modified polyester, and combinations thereof. ### Claim 6 (depends on 5) The golf ball according to claim 5, wherein in said ionomer composition, said second phosphorus-containing material is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said ionomer. ### Claim 7 (depends on 5) The golf ball according to claim 5, wherein said intermediate layer unit has an inner intermediate layer which encloses said core unit, and an outer intermediate layer enclosing said inner intermediate layer, at least one of said inner and outer intermediated layers being made from said ionomer composition. ### Claim 8 (depends on 1) The golf ball according to claim 1, wherein said core unit has a center core and a core layer which encloses said center core, at least one of said center core and said core layer being made from said rubber composition. ### Claim 9 A golf ball, comprising: a core unit made from a rubber composition which includes a rubber material, a halogenated organo-sulfur compound, and a first phosphorus-containing material selected from the group consisting of metal phosphate, polyphosphate, polyphosphoric ester, phosphonate, phosphate-modified polyester, and combinations thereof; a cover unit enclosing said core unit and made from a thermoplastic polyurethane composition; and an intermediate layer unit disposed between said core unit and said cover unit and encloses said core unit, said intermediate layer unit being made from an ionomer composition which includes an ionomer, wherein said ionomer composition further includes a second phosphorus-containing material selected from the group consisting of metal phosphate, polyphosphate, polyphosphoric ester, phosphonate, phosphate-modified polyester, and combinations thereof. ### Claim 10 (depends on 9) The golf ball according to claim 9, wherein in said rubber composition, said first phosphorus-containing material is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said rubber material. ### Claim 11 (depends on 9) The golf ball according to claim 9, wherein in said rubber composition, said halogenated organo-sulfur compound is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said rubber material. ### Claim 12 (depends on 9) The golf ball according to claim 9, wherein in said rubber composition, said halogenated organo-sulfur compound is selected from the group consisting of 2-chlorothiophenol, 3-chlorothiophenol, 4-chlorothiophenol, pentachlorothiophenol, a salt of pentachlorothiophenol, and combinations thereof. ### Claim 13 (depends on 9) The golf ball according to claim 9, wherein in said ionomer composition, said second phosphorus-containing material is present in an amount of at least 0.3 part by weight based on 100 parts by weight of said ionomer. ### Claim 14 (depends on 9) The golf ball according to claim 9, wherein said intermediate layer unit has an inner intermediate layer which encloses said core unit, and an outer intermediate layer enclosing said inner intermediate layer, at least one of said inner and outer intermediated layers being made from said ionomer composition. ### Claim 15 (depends on 9) The golf ball according to claim 9, wherein said core unit has a center core and a core layer which encloses said center core, at least one of said center core and said core layer being made from said rubber composition.
