Solitons due to the interaction of polarized waves in optically nonlinear media have been analysed using the Riemann-Hilbert transform. We consider the propagation and interaction of differently polarized two-frequency ultrashort optical pulses in a resonant medium consisting of three-level particles. The exact form of the solitons is obtained explicitly.
