Summary: | PROBLEM TO BE SOLVED: To provide a pigment which can be used for security applications.SOLUTION: There is used a pigment which has a flake-form transparent or semitransparent conductive core and at least one coloring dielectric layer surrounding the core in security applications for shielding or attenuating high-frequency electromagnetic radiation. The pigment is preferably used as a mixture with an organic colorant and/or an inorganic colorant and/or a conductive material. The conductive core has a transparent or semitransparent flake-form substrate and coating layers arranged on all or both sides of the flake-form substrate and it is preferable that the coating layers have a single-layered or multilayered structure and at least the outer layer of the coating layer is a conductive layer.SELECTED DRAWING: None
【課題】セキュリティ用途に使用可能な顔料を提供する。【解決手段】高周波電磁放射線の遮蔽または減衰のためのセキュリティ用途における、フレーク状の透明または半透明の導電性コアと、前記コアを取り囲む少なくとも1つの着色用誘電体層とを有する顔料の使用。前記顔料が、有機着色剤および/または無機着色剤および/または導電材料との混合物として使用されることが好ましい。前記導電性コアが、透明または半透明のフレーク状基体と、該フレーク状基体のすべての面または両面に配置されたコーティング層とを有し、該コーティング層が単層または多層の構造を有し、少なくとも該コーティング層の外層が導電層であることが好ましい。【選択図】なし |
