청구항

[ What is claimed is:] [16.]16. A method of coating a conductive substrate, comprising the steps of:(a) providing an aqueous electrocoat coating composition comprising an ionic resin having functionality reactive with isocyanate and a compound comprising a plurality of allophanate groups;(b) immersing a conductive substrate in said electrocoat coating composition;(c) applying a potential of electric current between an electrode and the conductive substrate to deposit a coating layer onto the conductive substrate; and(d) curing the deposited coating layer...
