CA 2623654
A document includes paper having an average surface roughness of at least about 0.5 microns and including one or more optical brighteners, and includes at least one image thereon wherein the at least one image includes clear binder and light absorbing material that absorbs light only at wavelengths below 350 nm. The image is substantially not detectable to a naked human eye through differential gloss or exposure to light having wavelengths of 365 nm or more, but may be revealed to the naked human eye by exposing the document to light having a wavelength at which the light absorbing material absorbs light.
La présente concerne un document ayant une rugosité de surface moyenne d'au moins environ 0,5 micron et incluant un ou plusieurs azurants, et comprend au moins une image dans celui-ci sur laquelle ladite image comprend au moins un liant transparent et un matériau absorbant la lumière aux longueurs d'onde inférieures à 350 nm. L'image est sensiblement indétectable à l'oeil nu humain par l'intermédiaire d'une brillance différentielle ou d'une exposition à la lumière de longueur d'onde de 365 nm ou plus, mais peut être révélée à l'oil nu en exposant le document à la lumière d'une longueur d'onde à laquelle la lumière est absorbée par ledit matériau absorbant.
