Abstract
An intermediate clear barrier coat is composed of at least one polymer or oligomer or combination in an aqueous or organic solvent carrier. This layer is placed between a basecoat layer containing pigment and a low VOC clearcoat layer and inhibits the components of the low VOC clear topcoat from inducing a shift of color in the basecoat.
