N2 - The pole Regge form of QCD amplitudes with gluon quantum numbers in cross-channels and negative signature, which underlies the BFKL approach to the theoretical description of semi-hard processes, is violated in the next-to-next-to-leading logarithmic approximation by contributions of three-Reggeon cuts. The presence of a colour quantum number and gluon Reggeization makes structure of Regge cuts in QCD different from the structure of the cuts in the old (before QCD) theory of complex angular momenta. In this talk the colour structure of three-Reggeon cuts is analysed.
