Method of enhancing the visibility of diffraction pattern surface embossment |
摘要 |
Methods for enhancing the visibility of and imparting a metallic luster to holographic and diffraction pattern surface embossments on transparent media such as plastic films (12) are disclosed. Enhancement is achieved by (1), metallic effect dyes or (2), metal flake inks containing minimal quantities of resinous binders (3), inks containing crystalline pigments that have metallic visual effects, or (4), inks containing pigments formed of optical stacks. The solvent used during application of the dye or ink must not be a solvent for the embossed surface.
