We study polarization properties of the macroscopic analogues of two-photonBell states. The effect of hidden polarization, i.e., polarization in thesecond (and higher) orders in the intensity is observed for the triplet stateswhile the singlet one is demonstrated to be nearly unpolarized at least up tothe fourth order. The arbitrary-order degree of polarization is introduced andapplied to the macroscopic Bell states.
