Summary:  We show that on the unit disk, the localization operators associated to admissible wavelets and separable symbols are paracommutators. We have obtained conditions on the symbol of the localization operator such that it can be expressed in terms of a paraproduct and also under certain other condition on the symbol it is a Fourier multiplier.
