Abstract
An improved process for applying an ultraviolet curable coating to tin free steel is disclosed in this invention, whereby prior to applying the main ultraviolet curable composition, a thin pre-coating of a monomer containing at least one ultraviolet polymerizable site of alpha beta ethylenic unsaturation and at least two carbonyl groups is first applied to the surface to be coated, to a thickness of at least about 10.sup..sup.-3 microns, and heated at temperatures ranging from 50.degree. to 125.degree. C. for 5-25 minutes. Following this step, an ultraviolet curable coating composition is applied and cured.
