The method includes: forming a highly impermeable protective layer by depositing an aqueous emulsion on a part of the tyre to be coloured; and depositing a coloured layer on the protective layer. The aqueous emulsion has at least a cross-linkable polymer base, and a surfactant of molecular formula (I): (R1CONR2CHR3COO-)nXn+ where R1 is an aliphatic group C6-C23, R2 is H or an aliphatic group C1-C8, R3 is H or an aliphatic or aromatic group C1-C8, X is a metal cation, preferably an alkaline cation, and n is an integer of 1 to 3. |
