Abstract: Disclosed herein is an aqueous coating composition containing an aqueous epoxy resin dispersion, an aqueous amine-functional resin dispersion and an aromatic carboxylic acid. The aqueous dispersion contains at least one specific di- and/or polyfunctional monomeric amine and at least one resin component including at least one specific polyfunctional organic amine. Further disclosed herein is a kit-of-parts including a base varnish containing the aqueous epoxy resin dispersion and a curing component containing the aqueous amine-functional resin dispersion as well as the aromatic carboxylic acid. Additionally disclosed herein is a process for producing a coating on the substrate as well as coated substrates resulting from said process. Cured coating layers formed from said compositions exhibit a good adhesion to the substrate as well as a high intercoat adhesion and blistering stability under humidity conditions without negatively influencing the excellent sandability and the good stone chipping properties.

Abstract: Disclosed herein are an aqueous dispersion including cationic polyvinyl alcohol modified polymer particles, an aqueous electrocoating material containing the dispersion and a process to produce an at least partially coated substrate using the aqueous electrocoating material. The aqueous dispersion can be prepared by reacting an intermediate including at least one polyvinyl alcohol polymer chain with a compound including at least one epoxide group and a least two blocked primary amino groups. Aqueous coating compositions including the aqueous dispersion result in improved leveling properties during film formation as well as an improved edge protection of the substrate without negatively influencing the surface roughness and adhesion as well as the deposition properties.
