Coating powder and/or waste coating powder (I) with a particle size distribution of 0.5-100 microns in which 40-60 wt% of all particles have a particle size of less than 10 microns and up to 20 wt% have a particle size of less than 5 microns is used as an additive in anodically deposited electrophoretic paint. Independent claims are also included for (a) anodically deposited electrophoretic paint containing binder(s), water, optional crosslink(s), pigment(s), filler(s) and/or other conventional additives, plus coating powder (I) as above; (b) a process for the production of such paint by mixing an aqueous binder dispersion with (I) and optional components as above; (c) a method for improving wrap-around in anodic electrophoretic coating by using a coating bath containing (I); (d) a method for anodic electrophoretic coating using paint as described in (a); (e) a substrate coated by this method.
