Abstract: The presently claimed invention relates to a composition comprising polyurethane polymer and diluents, which is used as an additive in coating formulations, in particular water-borne paint and coating formulations, for reducing the effect of the viscosity loss caused by the addition of colorants/pigment pastes thereby improving the viscosity stability in tinted coating formulations as well as the method for preparing the composition.
