An authentication article encapsulated in a curable coating on a substrate

摘要

A method of encapsulating an article within a coating of a substrate comprises: providing a substrate; applying a first receiving layer of a curable coating on the substrate; introducing one or more articles to be encapsulated; applying a second layer of a curable coating to the substrate over the receiving layer; and curing the coating, so that the article is encapsulated within the coating. The coating may be cured using ultra violet radiation. The article may be an authentication means comprising a RFID providing biometrics information to provide a tamper proof passport or identity card with laser printed text. Barcodes and magnetic information strips may be included. The substrate may also be a vehicle registration plate. Also, a method of forming a durable image comprises: providing a substrate which may be polyethylene terephthalate; depositing an image by ink jet printing on the substrate; spraying a curable water soluble lacquer coating over the image; and curing the coating. Printed organic light emitting polymers or diodes and other flat screen display devices may be disposed between layers of curable lacquer.
