Abstract
Abstract Sensible coatings comprised of a colored sensible material in a binder of aminotriazine resin and a polymeric material are disclosed. The coatings can be placed on a transfer base such as polyethylene terephthalate and transferred to enpaneled plastic card bases. These machine sensible cards are resistant to scratching and other surface damage. The sensible coating is easily transferred in one step and permanently heat sealed in a second step.
