We discuss the loss of entanglement under dissipation for a class of entangled coherent states of two modes of the electromagnetic field. The dynamics may be conveniently studied in a finite dimensional time dependent orthogonal basis for the case of superposing coherent states of real amplitudes on the line. Both asymptotic decays and finite disentanglement occur depending of the initial conditions.
