Title: METHOD FOR PREPARING IRIDESCENT PIGMENT FOR SECURITY AND SAFETY, COATED WITH ORGANIC AND INORGANIC COMPOSITE PHOSPHOR
Abstract:
The present invention relates to a preparation method for a security pigment, and more particularly, to a preparation method that can provide a security pigment having both aesthetic effects and security properties, wherein the method comprises the steps of: (a) preparing an organic binder solution including organic phosphor particles and inorganic phosphor particles; (b) preparing a substrate suspension by mixing and then stirring and dispersing a flake substrate and a solvent; and (c) mixing the substrate suspension and the organic binder solution to coat the surface of the flake substrate with the organic phosphor and inorganic phosphor particles.
