A coating process for electrical steel sheets using a varnish composition includes: a) applying a varnish composition coating layer onto the surface of an electrical steel sheet. The varnish composition comprises (A) about 1 to about 95 wt % of a resin comprising nucleophilic groups chosen from OH, NHR, SH, carboxylate and CH-acidic groups, and electrophilic groups which can react with the nucleophilic groups, wherein the resin is capable of transacylation in its main chain and/or side chain(s), (B) about 5 to about 75 wt % of an organic solvent and/or water, (C) 0 to about 40 wt % of a resin different from (A), (D) 0 to about 10 wt % of a customary additive, (E) 0 to about 40 wt % of a pigment, filler and/or nano-scaled particle and/or monomeric and/or polymeric element-organic compound, wherein the wt % is based on the total weight of the varnish composition; b) curing the applied coating layer.

A coating composition for a food or beverage can that includes an emulsion polymerized latex polymer formed by combining an ethylenically unsaturated monomer component with an aqueous dispersion of a water-dispersible polymer.
