The concept of an asymptotic dispersion relation associated with multi-Regge asymptotic behavior is introduced. A particular example for the six-particle amplitude is derived in detail. In this example there are 44 distinct spectral contributions, each of which is expressed as a triple integral over physical-region invariant variables. The integrands are just the corresponding invariant dispersion denominators together with three-fold discontinuities which are expressed as integrals of physical scattering functions and their conjugates.
