At least a metallic part of a metal or metallized reinforcer, at least the surface of which is at least partially metallic, is coated with a polybenzoxazine, the repeat units of which comprise at least one unit corresponding to the formulae (I) or (II):in which Z1 represents an at least divalent, aliphatic, cycloaliphatic or aromatic bonding group comprising at least one carbon atom and optionally at least one heteroatom selected from O, S, N and P; X1 and X2, which are identical or different, represent O or S; Ar1 and Ar2, which are identical or different, represent a substituted or unsubstituted phenylene group; and Z2 represents O or (S)n, the symbol “n” representing an integer equal to 1 or greater than 1. Such a reinforcement can be used for the reinforcement of a rubber article, in particular a motor vehicle tyre.
