Abstract
A process for multi-layer coating by application of a base coat layer of a water-borne base coat to a substrate and subsequent application of a clear coat layer of a powder clear coat, followed by joint baking of both coating layers, wherein said water-borne base coat contains an effective amount, preferably 0.5 to 10 wt. %, of one or more water-insoluble cellulose esters, largely avoids the formation of blisters in the powder clear coat layer.
