| description | The invention relates to a process for the preparation of a multi-layer coating film on an electrically conductive substrate, comprising the steps of electrodepositing on an electrically conductive substrate, a first coating composition to form an uncured electrodeposition coating film, applying an aqueous primer-surfacer coating composition to form an uncured intermediate coating film, and then simultaneously heating the substrate coated with the said coating films and curing both the uncured electrodeposition coating film and the uncured intermediate coating film to form a cured film, wherein the curing agent B is a capped isocyanate where the capping agents are selected from the group consisting of aliphatic linear or branched diols, hydroxyalkyl(meth)acrylates and >NH functional heterocyclic aliphatic or aromatic compounds, to coating films made by this process, and to substrates covered with such coating films. |
