Abstract Entangled states based on two coherent states 3π/2 out of phase with each other, i.e. |α> and
e^iФ|-iα>, as well as on a special state with a relative phase Ф=|α|², are constructed. By analysing the amount of entanglement it is evident that entangled states based on this special state can be used as an excellent resource for quantum teleportation. It is also revealed that these entangled states possess some nonclassical features.
