Claim:
A water-base adhesive mix for producing tyres, comprising, by weight, 5 to 80% water, 10 to 60% of a cross-linkable unsaturated-chain polymer base, 0.2 to 1% sulphur, 0.01 to 30% of a reinforcing filler, 0.1 to 3% zinc oxide, 0.1 to 1% of accelerating agents, and 0.1 to 15% of emulsifiers; said adhesive mix being characterized in that the reinforcing filler comprises a carbon black having —ArA y functional surface groups, where: Ar is an aromatic radical selected from the group consisting of phenyl, naphthyl, anthracenyl, phenanthrenyl, biphenyl and pyridinyl; A is a COO − or SO 3 − functional group; y is a whole number from 1 to 5 when Ar is phenyl, from 1 to 7 when Ar is naphthyl, from 1 to 9 when Ar is anthracenyl, phenanthrenyl or biphenyl, and from 1 to 4 when Ar is pyridinyl.
