Chromotropic security fibers are fibers which have one color in daylight and are therefore visible in the paper and which have another fluorescence color under Ultra-Violet.

These fibers are common in security documents and provide a third, more sophisticated level of protection than visible, fluorescent fibers of the same color.

Examples of these fibers are:

  • visible in daylight blue and fluorescent green or red,
  • visible in daylight green and fluorescent yellow or red,
  • visible in daylight yellow and fluorescent blue or green or red,
  • visible in daylight orange and fluorescent green or red,
  • visible in daylight red and fluorescent blue or green,
  • visible in daylight purple and fluorescent blue or red.

Created in 1985, PETREL is the French leader in the supply of security products for securing documents. Located in France, near Paris, PETREL manufactures and develops 3 main product lines: Security inks, security fibers and security sewing threads.
