<p>A technique is described that eliminates silvering on personalized plastic cards protected by a topcoat. A layer of polymeric material is applied to the card substrate and the printed personalization, such that the polymeric layer is disposed between the topcoat and the card substrate. The polymeric layer provides a number of benefits, including eliminating silvering by improving topcoat adhesion, improving abrasion resistance of the topcoat, enhancing plasticizer resistance, and permitting a lowering of topcoat lamination temperatures while maintaining durability.</p> |
