First Claim
Patent Images
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.

Abstract
An article having a radiation cured coating is formed by:
(a) applying to a substrate a first layer of pigmented or unpigmented radiation curable material containing glitter particles such as metallic particles or synthetic glitter particles;
(b) applying a second layer of unpigmented radiation curable material over the first layer, and
(c) curing the first and second layers with ionizing irradiation or ultraviolet light, either in two steps or in a single curing step after both layers have been applied.
