Disclosed is an aqueous dispersion of a transparent powder coating consisting of a solid powder component and an aqueous component. The solid powder component includes at least one epoxy group-containing binder, at least one crosslinking agent, and optionally catalysts, adjuvants, or additives typical for transparent powder coatings. The binder contains 30-45% glycidyl-containing monomers and optionally vinylaromatic compounds such as styrene. The crosslinking agent is preferably a straight-chain aliphatic dicarboxylic acid and/or a carboxy-functional polyester. The aqueous component includes at least one nonionic thickener and optional materials such as catalysts, adjuvants, and/or other such materials. The nonionic thickener is preferably a nonionic associative thickener. The invention also provides a process for preparing the aqueous dispersion of the invention and a process for coating a vehicle body with the aqueous dispersion of the invention.
