The method of factorizing the double-logarithmic contributions of soft virtual particles is used to obtain equations for the gluon bremsstrahlung amplitudes in quark--antiquark backward scattering at high energies. It is shown that for multi-Regge kinematics of the gluons these amplitudes are diagonal in color in the crossed channels. Explicit expressions for the amplitudes in special cases are given.
