A new source of dileptons emitted from a mixed quark-hadron phase, quark-hadron bremsstrahlung, is proposed. An estimate for the $ππ\toσ\to γγ$ process in nuclear collisions is given.6 pages, presented at XIII international conference Selected Problems of Modern Theoretical PhysicsNuclear Theorytext
