  We construct candidates for observables in wedge-shaped regions for a class
of 1+1-dimensional integrable quantum field theories with bound states whose
S-matrix is diagonal, by extending our previous methods for scalar S-matrices.
Examples include the Z(N)-Ising models, the A_N-affine Toda field theories and
some S-matrices with CDD factors.
  We show that these candidate operators which are associated with elementary
particles commute weakly on a dense domain. For the models with two species of
particles, we can take a larger domain of weak commutativity and give an
argument for the Reeh-Schlieder property.
