OG exemplary drawing
 
1. A deep drawn article, comprising:
a cured polymeric film having a first reaction product of a cationic photoinitiator and (3,4-epoxycyclohexylmethyl) adipate, a second reaction product of a free-radical photoinitiator and a vinyl ether selected from 4-hydroxybutyl vinyl ether and triethyleneglycol divinyl ether, and a third reaction product of a hydroxyl functional monomer and a thermal curing agent; and
a metal substrate, wherein the cured polymeric film coats the metal substrate, and wherein the metal substrate and the cured polymeric film have been deep drawn,
wherein the bis (3,4-epoxycyclohexylmethyl) adipate is incorporated into the first reaction product in an amount from 30% to 60% by weight based on the total weight of the polymeric film and the vinyl ether is incorporated into the second reaction product in an amount from 5 percent to 30 percent by weight based on the total weight of the polymeric film.
