The impulsive synchronization is investigated for a class of coupled dynamical networks with mixed delays and multiple disturbances. The model is more general due to the mixed delays and stochastic noise， which make the result more applicable. The ultimately bounded synchronization is proposed to replace the complete synchronization in previous literature in order to characterize the influence from exogenous disturbances. An improved difference inequality is established to overcome some difficulties caused from mixed delays. The derived results improve and extend some related works in previous literature.
