The vertex corrections of the dynamical spin susceptibility are calculated for a Hubbard model with intermediate coupling strength (U/t --7) and a Fermi surface approximating that of YBa2Cu307. The resulting q-dispersion of the coupling J(q) yields below T¢ for d~2\_y2-wave pairing a resonant-like p
