Abstract (en)
[origin: EP0395496A2] The invention concerns a sheet intended for prolonged exposure to light. It carries one at least light-resistant imprint having a first colour in natural light with a wavelength between 400 and 700 nanometres and a second colour, different from the first, in an artificial light with a wavelength of less than 400 nanometres and greater than 700 nanometres. The imprint is produced by photogravure printing with liquid ink containing at least one luminescent pigment capable of withstanding temperatures above 100 DEG C for at least 10 minutes. Use especially as a decorative sheet for laminates.
