1. Method of forming a radiation cured coating on a substrate comprising:

  • (a) applying by roll coating to the substrate a first layer between about 0.01 and about 0.1 mm thick of radiation curable material containing glitter particles in an amount of from about 4 to 33.3% by weight of said first layer;

    (b) applying by curtain coating to the surface of the first layer an unpigmented second layer between about 0.01 and about 0.15 mm thick of the same or a different radiation curable material in a wet-on-wet process; and

    (c) subjecting the first and second layers to ionizing irradiation or ultraviolet light in an inert atmosphere containing less than about 1,000 ppm oxygen in a one stage curing process after both layers have been applied to the substrate, to thereby cure the coating.
