Abstract
A rubber composition for manufacturing tyres is based on one or more diene elastomers, one or more reinforcing fillers, and a vulcanization system. The vulcanization system includes one or more 1,2,4-triazine compounds chosen from compounds of formula I and compounds of formula II: Certain specific 1,2,4-triazine derivatives are described.
