First Claim
Patent Images
1. A method of producing an identification card having visually detectable information, comprising:
- applying a plurality of color layers over each other on a synthetic carrier; and
forming the information by contacting the color layers with a controlled laser beam and selecting the energy of the laser beam and the color layer characteristics in such a way that a new color is formed restricted to a certain area, said new color being formed by an interaction between the color layers produced by at least partially melting the color layers with the laser beam.

Abstract
An identification card having information applied in the form of patterns, letters, numbers and/or images, formed by interruptions, in the homogeneity of different colored layer areas arranged superjacently on the identification card. The colored information can be produced by selectively removing the color layers by means of a controlled laser beam or by blurring or other chemical reactions induced by said beam. Thus identification cards can be produced having a high standard of security in spite of the simplicity of their production.
