In this paper, we study the dynamical entanglements in the interaction between an effective two-level atom with a two-mode field in the superposition of photon-added pair coherent states. The effect of adding photons on the entanglement degree is investigated. By using the master equation method and the linear entropy criterion in the Jaynes-Cummings model, we find that the degree of entanglement is enhanced. Besides, the dynamical behaviors of this model are found to be different compared to that of the corresponding of pair coherent state.
