(57) [Summary]nAn electrodeposition primer composition comprising an aqueous dispersion containing an ionic epoxy-based resin, a hindered amine light stabilizer, and an antioxidant mixture comprising a phenolic antioxidant and a sulfur-containing antioxidant. This primer composition is particularly suitable for use under a UV radiation transparent topcoat. This UV radiation causes delamination of the topcoat from the primer coat in the absence of the hindered amine and antioxidant mixture. |
