    Abstract: PROBLEM TO BE SOLVED: To suppress changes with time of the rubber when a rubber-steel cord composite to be used as the reinforcing material of a pneumatic tire or the like is stored in an unvulcanized state, and thereby to suppress reduction in adhesiveness of the composite after vulcanization and to improve adhesiveness of the vulcanized rubber-steel cord composite after wet-heat aging. SOLUTION: A rubber composition for coating a steel cord is provided, which is produced by compounding N-t-butyl-2-benzothiazole sulfenimide and a metal alkane dithiol expressed by general formula (1):M 2+ [S-(CH 2 ) m -S] 2- into a diene rubber component. In the formula, M represents Zn, Cu, Fe or Mn, and m represents 4 to 8. COPYRIGHT: (C)2011,JPO&INPIT
