Explicit expressions for the specific heat discontinuity of a two-band superconductor containing Anderson impurities are derived by means of diagrammatic techniques. Both interband and intraband contributions are treated. The results contain the already known limiting cases: the BCS, pure two-band, and dirty one-band behavior. It is found that the law of corresponding states still holds in a generalized sense.
