An aromatic polyphenol derivative which comprises at least one aromatic ring bearing at least two —O—Z groups in the meta position relative to one another, the two positions ortho to at least one of the —O—Z groups being unsubstituted, is used for the manufacture of a phenol-aldehyde resin for reinforcing a rubber composition. Each —O—Z group represents an —O—((C═O)(R1)) group with R1 representing a hydrocarbon-based radical or a substituted hydrocarbon-based radical.
